The short answer

If you own an AM5 board and want a faster processor

Four things, in the order they matter. One: AM5 accepts the Ryzen 7000, 8000 and 9000 desktop series, so on this socket the newest desktop Ryzen parts are in range of a board you may already own. Two: if your board is older than the processor you are buying, it needs a firmware update before it will start that processor — and that update has to happen while a processor the board already supports is installed, or through a no-processor flashing feature if your board has one. Three: unlike AM4, this socket is not finished. AMD has committed to supporting AM5 through 2029, announced at Computex 2026. Four: because of all that, you may not need to buy a new board at all. On a live socket the usual right answer is a processor and a firmware update, not a rebuild.

The rest of this page is the detail behind those four lines, including the two things the socket's long support horizon does not promise you.

What an AM5 board takes

Confirmed. AM5 is a land grid array socket with 1718 contacts, and it carries AMD desktop processors from the Zen 4 generation onwards. In Ryzen terms the desktop series it accepts are the 7000 series (Raphael), the 8000 series (Phoenix) and the 9000 series (Granite Ridge). AMD also ships Epyc 4004 and 4005 parts on the same socket for entry-level servers, which is not what most people reading this are shopping for, but it is the same physical socket.

That is the socket-level rule, and here is its limit, stated plainly: a processor fitting the socket is not the same as your board starting it. Whether a specific board runs a specific chip depends on the chipset, on the board maker, and on which firmware that maker chose to release for that model. Two boards with the same chipset from two vendors can differ. Two revisions of the same model can differ.

So we do not publish a list of which processors work in which boards, and we would not trust one that we did publish. Such a list is only correct until the next firmware release, across four vendors and hundreds of models, and being wrong about it costs you a build that will not start. The authority is your own board's CPU support list, published by the company that made it:

Find your exact model, open its CPU support page, and check two columns: whether the processor is listed at all, and which firmware version first supported it. If the processor is not on that list, it is not supported on that board, whatever the socket says.

Why your chipset tier still matters

An AM5 board is not one thing. An A620 board and a B650 board are both AM5, they both take the same processors, and they are not the same upgrade target. The socket tells you what fits. The chipset tells you what you can do with it once it is in.

Confirmed. The entry-level tier is where the difference bites. Compared with A620, the B650 chipset adds the features that make processor overclocking possible, chipset PCIe 4.0 support, and higher-speed USB 3.2. So an A620 board will run an unlocked Ryzen processor perfectly well — it just will not let you overclock it, and it gives you less connectivity to hang the rest of the system off.

Same socket, different ceiling

This is the part that gets flattened everywhere else. “AM5 supports Ryzen 9000” is true of an A620 board and of an X870E board, and those two boards are not the same purchase and not the same upgrade. If what you want out of the upgrade is overclocking headroom, faster storage lanes or more USB, that is a chipset question, not a socket question — and it is the question worth asking before you decide the board is the thing holding you back.

The 800-series lineup repeats the same shape at the bottom, and this is the one that catches people out: the entry-level B840 chipset drops processor overclocking too. A higher number does not mean a higher ceiling, and a B840 board is the A620 tier wearing an 800-series badge. Our chipset comparison has the tier-by-tier detail, and as always the specification that governs your board is on your board's own product page.

One thing chipset tier does not change: which processors physically fit. A620, B650, B850, X670E and X870E are all AM5 and all take AM5 processors. What varies underneath the chipset label is power delivery, and a high core-count part asks more of a board than the processor it replaces. That is a board-by-board question we cannot answer generically, and it belongs in the same place as everything else here: the manufacturer's page for your model, and our review of it if we have one.

The BIOS update comes first

This is the step that ruins weekends, and on AM5 it catches a specific group of people: anyone whose board is older than the processor they just bought. A 600-series board built around the launch of the Ryzen 7000 series shipped before the 9000 series existed, and a board that shipped before a processor existed does not know how to start it. A firmware update is more likely to be needed the earlier your board was manufactured.

The update that teaches it has to be installed before the new processor goes in — which normally means installing it while a processor the board already supports is still in the socket.

If you have already swapped the chip and the board will not start, there is a second route on some boards: flashing firmware from a USB stick with no processor installed at all. The feature has different names. ASUS calls it USB BIOS FlashBack, MSI calls it the Flash BIOS Button, GIGABYTE calls it Q-Flash Plus, and ASRock calls it BIOS Flashback.

We are not going to tell you whether your board has it. The feature varies by model and by board revision within a model, and we have not verified it per board. Look for a marked USB port and a small button on the rear panel, and confirm it on your board's own product page. Our review of your board, if we have one, records what the manufacturer publishes for it.

Two related non-claims, for the same reason. We do not print a minimum firmware version for any processor, because published minimums disagree between vendor product pages and vendor release notes and we have verified none of them per board. And we do not tell you a firmware release is safe; the release notes for your model do.

The mechanics of doing it — the USB stick format, the filename rule, what happens if you interrupt it, and what gets reset afterwards — are in our BIOS update guide, and the no-processor route in particular is covered there. One AM5-specific thing to expect afterwards: the first boot on new memory settings can take a long time while the board trains the memory, which is normal and is explained in our AM5 slow-boot guide.

Where AM5 ends

Confirmed. AM5 is the one live desktop socket here with a stated future. AMD has committed to supporting AM5 through 2029, a horizon it announced at Computex 2026, having previously extended it through 2027 at Computex 2024. A board bought on this socket today still has processor upgrades ahead of it without a new motherboard. We are stating that plainly for the same reason we state AM4's dead end plainly: it is what the reader needs in order to decide, and hedging it would be hedging in our own favour.

That said, the horizon is a commitment about the socket, and it is worth being precise about the two things it does not promise you.

It does not promise your board. AMD committing to the socket is not your board maker committing to your model. Whether a future processor runs in the board you own still depends on that vendor publishing firmware for that model, which is the same per-board question as the rest of this page and has the same answer: your board's CPU support list.

It does not move the memory. AM5 is DDR5 only. There is no DDR4 option on this socket at any tier, so a DDR4 kit from an older build does not come with you, and no firmware update changes that. In the other direction, the boundary is just as hard: an AM5 board will never accept an AM4 processor, and an AM4 board will never accept an AM5 one. No adapter, firmware update or chipset changes it. If that is the move you are weighing, the AM4 upgrade path page is the other half of the decision.

Stay on your board, or move up a tier?

Stay on the board you have if it takes the processor you want and the firmware exists for it. That is one processor, one firmware update, no new memory, no reinstall, no case work. For a large number of people reading this, that is the whole answer — a live socket is precisely the situation in which the cheapest real gain does not involve a new motherboard.

Move up a tier only if the thing limiting you is a chipset feature rather than the processor: overclocking headroom on an entry-level board, PCIe or M.2 lanes you have run out of, or connectivity you actually use. “My board is old” is not by itself a reason on a socket with years of committed support left, and a new board on the same socket does not make your existing processor faster.

If you do decide to move, these are AM5 boards we have written up across the tiers, so you can see what a step up actually buys: ASUS Prime A620M-A at the entry level, MSI MAG B650 Tomahawk WiFi in the mainstream, and ASUS ROG Strix B850-E Gaming WiFi on the 800-series side.

The compatibility and chipset claims on this page are socket-level statements, sourced as follows. Per-board claims are not made here at all — that is what the vendor support links above are for.

  • Confirmed — the 1718-contact socket, the Ryzen 7000, 8000 and 9000 desktop series, the Epyc 4004 and 4005 parts, DDR5-only memory, and the A620 to B650 feature difference including processor overclocking: Wikipedia: Socket AM5, read 24 August 2026.
  • Confirmed — the support horizon through 2029 announced at Computex 2026, and the earlier extension through 2027: Wikipedia: Socket AM5 and Tom's Hardware, both read 24 August 2026. This is the same citation carried by CPU Sockets Explained.
  • Authority for anything per-board — the manufacturer CPU support pages linked above, checked 24 August 2026. Three of the four block automated reading, which is one more reason we send you to them rather than copy them.

How we update this page

The same two tiers we use on other platform pages:

  • Confirmed — stated by the vendor on its own materials, or by an executive on the record. We may write it in our own voice.
  • Reported — carried by named outlets that identify their source. We attribute it every time, and it never goes in a specification table.

The claim on this page with an expiry date is “AMD has committed to supporting AM5 through 2029”. A support horizon is the kind of claim that gets extended rather than broken, and it has already moved once, so we re-check it every 6 months and immediately if AMD makes a platform announcement. The owner accountable for that re-check is @DtotheK. As above, a re-check that finds nothing new changes no date on this page.

One thing we deliberately do not do: publish per-board CPU support tables or minimum firmware versions. Those would need re-checking against four vendors' releases forever, and a stale one is worse than none.
