AM4 vs AM5 is no longer a nostalgia debate. AMD’s US store lists the Ryzen 7 5800X3D at $349 and the Ryzen 7 9850X3D at $499, according to Windows Forum’s October price check. That is a $150 gap on the chip alone. Reports from October 23 to 25 add a twist: the older processor is reportedly back in production.
The gap sounds small until you add the rest of the bill. The 5800X3D drops into an existing AM4 board and reuses DDR4 memory. The 9850X3D needs an AM5 board and DDR5. Whether the extra money buys you anything depends on what you own today, which graphics card you run, and how long you plan to keep the machine. If you already follow the AM5 lineup, our Ryzen 9800X3D vs 9850X3D breakdown covers the step up inside the platform. This guide covers the step between platforms.
One ground rule before we start. AMD’s pages and the October coverage give us prices, dates and platform facts, but no clean benchmark table that puts these two chips head to head. We will not invent frame-rate percentages. Where a figure comes from a single outlet, the text says so. Where we have no number, we show you how to measure it on your own PC.

AM4 vs AM5 Specs: Ryzen 7 5800X3D and 9850X3D Side by Side
The table below sticks to facts that AMD publishes or that at least two sources confirm. Rows marked as analysis follow directly from those facts, such as which parts you must buy. Anything that rests on one outlet’s relay of an AMD store listing sits in the paragraphs after the table.
| Attribute | Ryzen 7 5800X3D (AM4) | Ryzen 7 9850X3D (AM5) |
|---|---|---|
| Socket | AM4 | AM5 |
| Memory type | DDR4 (AM4 platform) | DDR5 |
| Product family | Ryzen 5000 series | Ryzen 9000 Series |
| AMD US store price, Oct. 24 to 26, 2026 | $349 | $499 |
| CPU price gap | Baseline | +$150 |
| Observed third-party price, October 2026 | Not tracked here | $484 to $499 |
| Special edition | 10th Anniversary Edition, available from June 25, suggested etail price $349 | None |
| AMD platform support pledge | AM4 support continues through 2029 | AM5 support continues through 2029 |
| Motherboard | Reuse a compatible AM4 board (analysis) | New AM5 board required (analysis) |
| Memory kit | Reuse existing DDR4 (analysis) | New DDR5 kit required (analysis) |
| AMD store stock, Oct. 26 | Listing active, check stock | Marked out of stock, one-unit limit |
| Typical buyer | Existing AM4 owner chasing gaming frames | New build or full platform move |
Several specs live outside the table on purpose. Single-source reports say both chips carry eight cores and 16 threads. They also say the 5800X3D boosts to 4.5 GHz, while the 9850X3D runs a 4.7 GHz base clock, a 5.6 GHz boost, 104 MB of total cache and a 120 W default TDP. Treat those numbers as reported until you check AMD’s product pages yourself. They match the general shape of the two chips, but we could not confirm each one against two independent pages.
The rows labelled analysis matter most. A CPU swap on AM4 costs one component. A move to AM5 costs three: processor, board and memory. Every comparison of AM4 vs AM5 comes back to that arithmetic, and it explains why a $150 sticker gap understates the real difference.
Where the Ryzen 7 5800X3D Stands in October 2026
The 5800X3D story has three dates. On May 31, AMD marked ten years of the AM4 socket and said it would keep supporting both AM4 and AM5 through 2029. It also announced the Ryzen 7 5800X3D 10th Anniversary Edition, which AMD said would reach shelves from June 25 at a suggested etail price of $349. Our look at the 5800X3D anniversary edition tracks how street pricing behaved after launch.
The third date is the newest. Between October 23 and 25, several outlets reported that AMD is bringing the chip back. Tom’s Hardware reported that AMD chair and CEO Lisa Su proposed the revival and set the plan in motion before the DDR5 shortages began. The headline frames the chip as a parting gift to loyal owners of the ten-year-old socket. TheFPSReview ran a similar story on October 23. Other coverage says production restarted after manufacturing-process work with TSMC, and that an AMD executive named Travis Kirsch credited Su as one of the proponents.
What is confirmed and what is only reported
AMD’s own store lists the 5800X3D at $349 as of October 24 to 26. That matches the anniversary edition’s launch price. The store also shows the 9850X3D and the older 9800X3D as purchasable products, so nobody can call the 5800X3D retired. Those are the confirmed pieces.
The pieces we could not confirm are the ones buyers care about most. We found no separate AMD press release for the October revival on the newsroom pages we checked. We found no official price for a new production run, and no ship date. If you read a breathless headline promising a flood of cheap 5800X3D stock, hold it at arm’s length. The sensible reading today: AMD still sells the chip at $349, and reporters say more supply is coming.
What the Ryzen 7 9850X3D Brings to AM5
The 9850X3D is the newest Ryzen 7 X3D chip on AM5. AMD’s driver and downloads page files it under the Ryzen 9000 Series, and retail listings identify it as an AM5 chip that uses DDR5. Reports say AMD announced it on January 5, 2026, with retail availability starting in the first quarter, and that AMD’s listing gives a January 29, 2026 launch date.
Its predecessor, the Ryzen 7 9800X3D, still sits in AMD’s store at a reported $479. That is $20 below the 9850X3D. Our 7800X3D vs 9800X3D vs 9850X3D comparison weighs that smaller gap in detail. For this article the 9800X3D matters only as a fallback. If the 9850X3D stays out of stock, the older chip is the logical stand-in on the same socket.
Stock is the practical headache. On October 26 the AMD store marked the 9850X3D out of stock and capped purchases at one unit per customer. Third-party observers saw October street prices between $484 and $499. A product that sells out at its list price usually signals demand that exceeds supply, and that tends to hold prices flat rather than push them down.
AMD also positions AM5 as the longer runway. The company tied its extension of AM5 support through 2029 to the launch of the Ryzen 7 7700X3D, an AM5 X3D chip that AMD said would arrive July 16 at a suggested etail price of $329. For a buyer deciding on a platform rather than a single chip, that date matters as much as any frame rate.
Pricing: The $150 CPU Gap Is Only the Start
Every price below comes from AMD’s announcements, AMD’s store listings as relayed by Windows Forum, or retailer observations. We left out the cost of AM5 motherboards and DDR5 kits because our sources did not give a verified figure for either. Price them yourself at a retailer you trust before you commit.
| Item | Price | Basis |
|---|---|---|
| Ryzen 7 5800X3D, AMD US store | $349 | Store listing, Oct. 24 to 26, 2026 |
| Ryzen 7 5800X3D 10th Anniversary Edition | $349 | AMD suggested etail launch price, available from June 25 |
| Ryzen 7 7700X3D (AM5) | $329 | AMD suggested etail launch price, available from July 16 |
| Ryzen 7 9850X3D, AMD US store | $499 | Store listing, Oct. 26, marked out of stock |
| Ryzen 7 9850X3D, third-party observations | $484 to $499 | Retailer and media observations, October 2026 |
| CPU gap, 9850X3D minus 5800X3D | $150 | Arithmetic on AMD store prices |
Read the table as a floor, not a total. An AM4 upgrade stops at $349 if your board already supports the chip. An AM5 move starts at $499 and grows with every part you replace. Our AM4 build costs against AM5 coverage runs the full-system math with component prices, and it points the same direction: the older platform wins on total spend.
Cost per year of useful life
Suppose you keep a PC for four years. The AM4 path spends $349 and gets a drop-in boost now. The AM5 path spends at least $499 plus the board and memory, but it leaves you with a socket AMD promises to support through 2029 and a chip near the top of the stack. If you upgrade the CPU again in year three or four, AM5 lets you do it without a new board. AM4 offers no such comfort beyond the chips that already exist.
Resale shifts the math a little. Your old Ryzen 5000 or 3000 processor, your DDR4 kit and your old board all carry some resale value, and an AM5 move frees all three for sale while an AM4 swap frees only the processor. That offsets part of the AM5 bill, though it also costs you time and the usual marketplace haggling. Price your used parts before you decide, and count only what you will really sell.
Benchmarks: Three Kinds of Evidence and What Each Tells You
A fair AM4 vs AM5 comparison needs frame-rate data, so here is where that data comes from and how far to trust it. We pulled three evidence streams. None gives us a number we can publish without a caveat, and we would rather say so than dress up guesses as measurements.
Source one: AMD’s own generational claim
AMD’s page for the first AM5 generation says Ryzen 7000 processors can deliver up to 49% more performance at the same power level compared with the last generation. That is a vendor claim about a different pair of chips, and it describes power efficiency, not gaming frames. It tells you AMD built AM5 for efficiency gains. It does not tell you what a 5800X3D owner gains in a specific game.
Source two: third-party roundups
Windows Forum published two comparisons that matter here. One sets the 9850X3D against Intel’s Core Ultra 7 270K Plus across gaming, productivity, power and value. The other lines up the 7700X3D, 7800X3D, 9800X3D and 9850X3D in gaming benchmarks. NeoTeo relayed a PC-Centric report that the 9850X3D leads in Fortnite and CS2. All three agree on the direction: the newest AM5 X3D chip sits at or near the front of gaming charts. None includes the 5800X3D in a head-to-head that we could verify, so the direct AM4 vs AM5 delta stays unpublished here.
The Intel comparison deserves a sentence of context. It shows that AMD’s X3D chips face a live rival on a third platform. If you are building new, that rival belongs on your shortlist. If you own an AM4 board, it does not, because choosing Intel means replacing the board and memory just like the AM5 move does.
Source three: your own test
The most reliable benchmark is the one on your PC. Pick the two or three games you play most. Run a repeatable scene at your real resolution and settings, and log average frames plus the slowest one percent of frames. Do it once on your current CPU and write the numbers down. Then compare them with a reviewer who uses the same game and a similar graphics card. If your slowest one percent already sits close to your average, the CPU is not your bottleneck, and neither chip will transform your experience.
A simple protocol keeps the test honest. Close background apps and reboot. Pick one repeatable scene, such as a fixed route through a city or a replay of the same match. Run it three times and keep the median result. Record your graphics card usage while it runs. If the card sits near full load, the processor has headroom to spare, and any 5800X3D vs 9850X3D debate is academic for you. If card usage drops while one CPU core pins at full load, you have found a real processor limit, and an upgrade will help.
That last point deserves more weight than any chart. A processor swap only helps when the processor limits the frame rate. At 4K with a mid-range graphics card, the GPU limits it, and a $150 premium for the 9850X3D buys you nothing visible. At 1080p or 1440p with a fast graphics card and a high-refresh monitor, the CPU limit appears quickly, and the larger cache on the X3D chips pays off.
Gaming Performance by Resolution and Game Type
Without a verified head-to-head, the honest guidance comes from how X3D chips behave. Both processors carry AMD’s 3D V-Cache, which stacks extra cache on the die. That cache helps most in games that hammer the CPU with many small, latency-sensitive requests. Strategy games, simulation titles, large open-world games and competitive shooters sit in that group.
Here is how the choice plays out in practice:
- 1080p, high refresh, fast GPU: The CPU limits most often here, so the 9850X3D’s newer design and higher reported clocks matter most. The 5800X3D still holds up but trails.
- 1440p, high settings: The gap narrows. Many games bind to the GPU at this resolution, so the cheaper chip often delivers most of the experience.
- 4K: The graphics card dominates. Spend on the GPU before the CPU.
- Simulation and strategy: Cache-heavy workloads favor either X3D chip over a non-X3D processor. The newer chip adds headroom for big late-game maps.
- Streaming while gaming: Encoding competes for CPU time. Both chips reportedly have eight cores, so heavy multitasking pushes you toward a higher core count instead.
If your workload leans on productivity more than frames, neither chip is the right pick. Eight cores cap multi-threaded work, and our 9800X3D vs 9950X3D vs Intel 285K test shows where higher core counts start to pay off. A streamer who also edits video should read that before buying either processor here.
Frame pacing deserves a mention too. A faster average does not guarantee smoother play. The slowest one percent of frames decides whether a game feels fluid, and big caches tend to help there. That is the main reason X3D chips earned their reputation, and it explains why an older X3D processor can still beat newer non-X3D chips in many titles. When you compare, look at both numbers.
Platform Differences: DDR4, DDR5, BIOS and Support Dates
The chip is half of the decision. The platform is the other half. AM4 is a DDR4 platform. AM5 uses DDR5, and the two memory types do not fit the same slots. If you own a good DDR4 kit, an AM4 upgrade keeps it. An AM5 move retires it, though you can sell it to offset part of the cost.
AMD’s pages describe AM5 as a platform with PCIe 5.0 and Wi-Fi 6E features for the Ryzen 7000 generation. Whether you benefit depends on your other hardware. A PCIe 5.0 slot only matters if you own a graphics card or SSD that uses it. Most buyers will not notice the difference in daily use today.
Support dates deserve scrutiny. AMD’s May 31 announcement says it will support both sockets through 2029. That is a long promise for a ten-year-old design, and it reads as AMD’s answer to buyers who feared AM4 had no future. The October revival reports fit the same pattern. Still, support is not the same as new processors. AMD has not published a list of future AM4 chips, and we found no official roadmap for them. A reported six-core Ryzen 5 7500 for AM5 hints that AMD keeps filling out the cheaper end of the newer socket too.
BIOS and compatibility
The 5800X3D arrived years after many AM4 boards shipped. If your board is older, check its maker’s CPU support list and update the BIOS before you swap the chip. Skipping that step is the most common way a drop-in upgrade turns into a no-boot afternoon. On AM5 the same rule applies in reverse: a board that sat in a warehouse for a year may need a BIOS flash before it recognizes a newer processor.
Power and cooling
Reports put the 9850X3D at a 120 W default TDP. We could not confirm a matching figure for the 5800X3D, so we will not compare the two on watts. The practical advice holds either way. Match your cooler to your case and your noise tolerance, check the cooler maker’s AM5 mounting notes before you buy, and watch temperatures in your first long gaming session. A chip that throttles in a cramped case loses the very frames you paid for.
Real-World Examples From October 2026
Specs and prices only go so far. Six recent events show how this decision plays out in the market right now.
- AMD’s anniversary edition (May 31, June 25): AMD itself chose to ship a special-edition AM4 chip at $349 ten years after the socket launched. A company that wanted AM4 buyers to move on would not do that.
- The Ryzen 7 7700X3D (July 16): AMD launched this AM5 X3D chip at a suggested $329, $20 below the 5800X3D’s $349. It signals that AMD wants a cheaper doorway into AM5 as well, and AMD extended AM5 support through 2029 alongside it.
- The revival reports (October 23 to 25): Tom’s Hardware, TheFPSReview and others reported that Lisa Su proposed bringing the 5800X3D back. The plan reportedly predates the DDR5 shortage, which weakens the idea that AMD revived the chip only because DDR5 got expensive.
- Sold-out 9850X3D (October 26): AMD’s own store marked the chip out of stock with a one-unit cap. Buyers who wanted a launch-price chip that day had to look elsewhere.
- The wrong-box incident (October): VideoCardz reported a buyer who ordered a 9850X3D on two consecutive days and reportedly received an Intel processor in a sealed box both times. That is an individual retailer-order allegation, not a sign of any problem with AMD’s product.
- Retailer price cuts (October): Club386 reported that Amazon cut prices on AMD X3D chips, from the 5800X3D up to the 9950X3D. Prices move fast, so check the live number before you buy.
The pattern across all six: AMD serves both camps, supply on the newest chip runs tight, and prices swing at retail. That favors patience over panic buying.
Which Chip for Which Buyer: Seven Use Cases
Use the table below as a quick filter, then read the notes that follow for the reasoning behind the main picks.
| Your situation | Better pick | Why |
|---|---|---|
| AM4 board, DDR4, mid-range GPU, 1440p gaming | 5800X3D | One $349 part, no new board or memory |
| Building a new PC from scratch | 9850X3D | Current platform, support promised through 2029 |
| High-refresh 1080p esports with a fast GPU | 9850X3D | CPU limits frames most here |
| 4K gaming on a mid-range GPU | Keep your CPU, buy a GPU | The graphics card sets the frame rate |
| Streaming, editing and gaming on one PC | Neither, look at more cores | Eight cores cap multi-threaded work |
| Tight budget with an older AM4 chip | 5800X3D | Lowest cost for a large gaming gain |
| Want the platform to last through the decade | 9850X3D or a cheaper AM5 X3D | AM5 support runs through 2029 |
The AM4 owner with a mid-range card
This buyer gets the best return from the 5800X3D. An older Ryzen chip often holds back a decent graphics card in CPU-heavy games, and the swap fixes it for $349 with no other purchase. Reselling the old processor recovers part of the cost. Our 9800X3D vs 7800X3D comparison shows the AM5 version of this logic, where the cheaper older chip keeps most of the performance.
The new builder
Starting from nothing, AM4 makes little sense unless you find a bargain on a used board and memory. The 9850X3D, or a cheaper AM5 X3D chip such as the 7700X3D, gives you a platform AMD backs through 2029 and a route to a faster chip later. Pay the premium for the platform, not for the last few frames.
The competitive player
Esports players at 1080p with a high-refresh display chase every frame and every consistent frame time. Here the 9850X3D earns its price, and the NeoTeo report of a Fortnite and CS2 lead supports the instinct. If the chip is out of stock, the 9800X3D is a sensible stand-in.
The patient buyer
Some readers can wait, and for them waiting has real value. The 9850X3D sold out at AMD’s store on October 26, and the 5800X3D revival has no confirmed price or date. Two things could improve within weeks: supply on the newer chip and pricing on the older one. If your current PC still plays your games acceptably, set a price alert on both and revisit in two to four weeks. If you wait, set a ceiling in advance. The 9850X3D costs about 43% more than the 5800X3D at AMD’s store prices, so decide ahead of time what premium you will pay and walk away from anything above it.
A five-question test for the 5800X3D vs 9850X3D choice
Answer these in order and stop at the first answer that settles it.
- Do you own a working AM4 board that supports the 5800X3D? If no, the 5800X3D loses its main advantage, because you would buy a board for a dead-end socket.
- Does your graphics card sit below full load in the games you play? If it does, a faster CPU will help. If not, spend on the GPU instead.
- Do you play at 1080p or 1440p on a high-refresh display? If yes, CPU limits show up sooner, which strengthens the case for either X3D chip.
- Do you plan to keep this PC past 2029? If yes, lean toward AM5, since AMD’s support pledge for that socket runs through 2029.
- Is an extra $150 plus a board and DDR5 kit comfortable for your budget? If not, buy the 5800X3D and move on.
Most AM4 owners stop at question one or two. Most new builders stop at question one and head to AM5. The harder cases sit in the middle: players with an AM4 board and a fast graphics card who want a long-lived system. For them the 5800X3D vs 9850X3D question becomes a bet on how long the current board will survive, and the answer is a personal one.
Migration Guide: Moving From AM4 to AM5 in 10 Steps
If the use-case table points you to AM5, follow this sequence. It keeps downtime short and protects your data. Plan on a free afternoon.
- Back up everything. Copy documents, game saves and browser profiles to an external drive or cloud storage before you touch hardware.
- Record your current parts. Note your board model, memory kit and cooler so you can judge what to sell or reuse.
- Check cooler compatibility. Look up your cooler maker’s AM5 mounting guidance. Some coolers ship with the right bracket, others need an adapter.
- Buy the three core parts together. Pick the AM5 board, the DDR5 kit and the CPU in one order so a stock shortage on one item does not strand the others.
- Check the new board’s BIOS. Read the board maker’s CPU support list and flash an update first if the 9850X3D needs a newer version.
- Remove the old parts carefully. Power down, unplug, discharge static and photograph your cable layout before you pull anything.
- Install the CPU, cooler and memory. Seat the processor without touching the pads, apply thermal paste, and fit the DDR5 sticks in the slots the manual names.
- Enable the memory profile. In the BIOS, switch on the EXPO or XMP profile so the kit runs at its rated speed.
- Reinstall or repair Windows. A new platform often needs a clean install. Windows may boot an old install, but fresh chipset drivers matter either way.
- Test and tune. Run a stress test, watch temperatures, then try mild tuning. Our guide to undervolting your Ryzen CPU in Ryzen Master walks through that step.
Before you buy anything, confirm what you have today. This PowerShell snippet lists your processor, motherboard and memory in one pass:
Get-CimInstance Win32_Processor | Select-Object Name, SocketDesignation
Get-CimInstance Win32_BaseBoard | Select-Object Manufacturer, Product
Get-CimInstance Win32_PhysicalMemory | Select-Object Manufacturer, Speed, ConfiguredClockSpeedThe first line reports the socket. If it says AM4, the 5800X3D path is open to you after a BIOS check. The second line gives the board model you need for that check. The third shows whether your memory runs at its rated speed, which tells you if an AM5 move should include a better kit.
Common mistakes during an AM5 move
Four errors cause most of the grief. Buyers pair a DDR5 board with DDR4 memory they already own, which does not fit. They forget the cooler bracket and wait days for an adapter. They skip the BIOS check and stare at a black screen. And they leave the memory profile off, so a DDR5 kit runs far below its rated speed and drags the whole system down. Each one takes minutes to avoid and hours to fix after the fact.
A fifth mistake costs money rather than time. Some buyers pick the 9850X3D when a cheaper AM5 chip would do the job at their resolution. If your games run at 4K, the extra spend on the top X3D part rarely shows up on screen. Match the processor to the bottleneck you measured, not to the headline.
Staying on AM4: The Drop-In Upgrade Checklist
The cheaper path has its own steps, and they take about thirty minutes if nothing goes wrong. Start with the board. Find the exact model name, then open the maker’s CPU support page and look for the 5800X3D with the minimum BIOS version listed beside it. If your current BIOS sits below that version, flash it before you swap the chip. Do this while the old processor still sits in the socket.
Next, check cooling. Reapply thermal paste, confirm the mount is tight, and watch temperatures during your first long gaming session. A new chip can load the cooler differently than the old one, and a cooler that handled your previous processor with ease still deserves a look. Our CPU undervolting guide explains how to trim heat once the new chip runs.
Then check memory. Your existing DDR4 kit keeps working, but speed and latency still affect X3D chips, so confirm that your memory profile is on. Finally, test with the games you play. If your slowest one percent of frames improves, the upgrade worked. If it barely moves, your graphics card was the limit, and you saved the cost of a platform change.
Pros and Cons of Each Path
Ryzen 7 5800X3D on AM4
- Pro: $349 on AMD’s store, the lowest cost of entry in this comparison.
- Pro: Reuses your AM4 board and DDR4 memory, so no extra parts.
- Pro: AMD says AM4 support continues through 2029.
- Con: No confirmed future AM4 chips, so this is the end of the road for CPU upgrades.
- Con: Supply and pricing of any revived production run remain unconfirmed.
- Con: Needs a BIOS check on older boards.
Ryzen 7 9850X3D on AM5
- Pro: The newest Ryzen 7 X3D on a socket AMD promises to support through 2029.
- Pro: Leads gaming in the third-party roundups we found.
- Pro: DDR5 and newer platform features give you room to grow.
- Con: $499 list, $150 above the 5800X3D before any other part.
- Con: Needs a new board and DDR5 memory.
- Con: Out of stock at AMD’s store on October 26 with a one-unit cap.
Buying Risks: Stock, Scams and Price Swings
Hot processors attract trouble. Three risks stand out this month. First, stock. A chip that sells out at list price invites resellers, and resellers charge more than AMD. Check AMD’s own store first, then major retailers you already trust.
Second, fulfillment errors and scams. The sealed-box incident reported in October involved a buyer who got the wrong processor. Inspect the packaging on arrival, record an unboxing video, and read the CPU markings before you install. If the box looks tampered with, refuse it or start a return the same day. Keep the receipt either way.
Third, price swings. Retailers cut X3D prices in October, and a revival of 5800X3D supply could push that chip lower. If you can wait two weeks, you lose little. If your current PC runs poorly today, buy now and stop worrying about a $20 difference.
Verdict: When $349 Wins and When $499 Wins
In the 5800X3D vs 9850X3D matchup, the data points one way for most readers. If you already own an AM4 board and DDR4 memory, buy the Ryzen 7 5800X3D at $349 and keep the $150 or more you would otherwise spend on the platform. You get a large gaming gain in CPU-limited titles, you skip two extra purchases, and AMD still promises AM4 support through 2029. That makes AM4 the winner on value for existing owners.
If you build from scratch, or you plan to keep the machine into the next decade, buy the Ryzen 7 9850X3D at $499 or one of its cheaper AM5 siblings. You pay a $150 chip premium plus the board and memory, but you get the newer chip, DDR5 and a socket with a published support date. AM5 wins on longevity.
Two caveats limit how far this verdict stretches. We found no verified head-to-head benchmark between these two chips, so we cannot rank them by frames. We also could not confirm AMD’s October revival with a primary source, so treat any promise of new 5800X3D stock as a rumor until AMD publishes one.

FAQ: AM4 vs AM5 in 2026
Is AM4 dead in 2026?
No. AMD said on May 31 that it will support AM4 and AM5 through 2029, it announced a 5800X3D anniversary edition for June 25, and its store still lists the 5800X3D at $349.
Is the 5800X3D worth buying now?
It is worth it if you already own a compatible AM4 board and DDR4 memory and your games run into a CPU limit. It makes less sense for a new build, where AM5 offers a longer runway.
How much more does the 9850X3D cost than the 5800X3D?
The CPU alone costs $150 more on AMD’s store, at $499 against $349. You also need an AM5 motherboard and DDR5 memory, which add to the total.
Can I use my DDR4 memory on AM5?
No. AM5 uses DDR5, and the 9850X3D is an AM5 chip that uses DDR5. Your DDR4 kit stays with an AM4 system.
Did AMD officially relaunch the 5800X3D?
Several outlets reported a revival between October 23 and 25, and AMD’s store lists the chip at $349. We found no separate AMD press release, no new price and no ship date for a new production run.
Is the 9850X3D in stock?
