How Long AM5 Socket Support Lasts, and Where LGA1851 Stops

How long AM5 support lasts, and where LGA1851 ends
AMD extends support for Socket AM5 through 2029. It announced this at Computex on May 31, 2026. On Intel’s side, LGA1851 has no announced CPUs beyond the Core Ultra 200S Plus refresh, and Intel’s own engineering listing ties its next desktop platform to a new socket.
Start where your situation fits:
- Planning a new build: the socket runway matrix compares both platforms side by side.
- Own an AM5 board: the three-point board check shows whether a future Ryzen will actually run on it.
- Own a Z890, B860, or H810 board: the LGA1851 section covers your last confirmed drop-in upgrade.
Socket runway is one factor, so still check full motherboard compatibility before you order.
ℹ️ Risk Note: Moving to a newer CPU usually means updating your motherboard’s BIOS, and an interrupted or wrong update can leave a board unable to boot. Back up your settings, use only your board manufacturer’s file and method, and contact their support if anything is unclear.
What AMD’s “through 2029” promise actually covers
AMD’s promise is a platform commitment, not a guarantee for every motherboard.
From 2025+ to 2027+ to 2029
When Ryzen 7000 (Zen 4) launched on AM5 in 2022, AMD promised support through “2025+.” It moved that to “2027+” with Zen 5 in 2024. AMD’s Computex 2026 announcement now extends the window through 2029.
Which CPUs already run on AM5
The socket has carried Ryzen 7000, Ryzen 8000G APUs, Ryzen 9000, and Ryzen 9000X3D. The newest is the Ryzen 7 7700X3D, released July 16 at a $329 suggested launch price (as of July 2026).
Where Zen 6 stands
AMD’s documentation lists the Ryzen 10000 “Olympic Ridge” desktop CPUs as AM5-compatible, according to TechPowerUp’s report on the documentation update. AMD has not announced model numbers, pricing, or a launch date. Benchlife reports desktop Zen 6 won’t launch before 2027, which is a report rather than an AMD statement.
🔍 Why It Works: A socket commitment means AMD keeps designing new desktop CPUs to fit AM5 boards. Whether your board runs one depends on its maker shipping a BIOS update that adds support for that CPU.
Is LGA1851 a dead end after Arrow Lake Refresh?
LGA1851 has carried two waves of Arrow Lake CPUs, and Intel has announced nothing after them.
What’s confirmed: Core Ultra 200S and 200S Plus
Arrow Lake’s Core Ultra 200S chips launched October 24, 2024, on LGA1851 with new 800-series chipsets. The refresh, called Core Ultra 200S Plus, drops into existing 800-series boards after a BIOS update. It also raises official memory support to DDR5-7200.
In July 2026, Intel raised its recommended prices. The Core Ultra 7 270K Plus is now $339–$349, and the Core Ultra 5 250K Plus is $219–$229 (as of July 2026).
What’s reported: Nova Lake on LGA1954
Intel’s Design-In Tools store lists an ILM kit for “LGA1954 NVL-S,” as VideoCardz reported from the Intel listing. It’s validation hardware, not a product announcement. A leaked Intel slide covered by Tom’s Hardware points to 900-series chipsets and first chips in Q1 2027. Intel has not confirmed a launch date or issued a formal end-of-life notice for LGA1851.
🧩 Compatibility Check: Before buying a 200S Plus chip for an existing 800-series board, open that board’s CPU support list and confirm the minimum BIOS version it needs.
AM5 vs LGA1851: which socket gives you more upgrades
If you want a CPU upgrade later without replacing the board, only AM5 has an official support window.
| Socket | CPUs so far | Vendor’s stated window | Next CPUs (status) | Key Detail |
|---|---|---|---|---|
| AM5 | Ryzen 7000, 8000G, 9000, 9000X3D, 7700X3D | Through 2029 (AMD, May 31, 2026) | Ryzen 10000 “Olympic Ridge”: listed in AMD docs; no launch date | Best for planned CPU swaps later |
| LGA1851 | Core Ultra 200S (Oct 2024), 200S Plus (2026) | None published | None announced | Best if you won’t change CPU on this board |
| LGA1954 | None yet | None published | Nova Lake-S: in an Intel validation listing; Q1 2027 per leak | New board required |

The table can’t tell you which AM5 board to buy. Chipset tier affects PCIe lanes and overclocking, so compare how A620, B650, B850, and X870 boards differ before choosing.
Will your AM5 board actually get Zen 6? Check 3 things
AMD’s 2029 commitment covers the socket, but your motherboard maker decides which CPUs each board supports.
Your board’s CPU support list
Each board maker publishes a CPU support list for every model. A CPU that isn’t on that list isn’t supported, even if it fits the socket.
BIOS version and flash-chip size
New CPU support arrives through BIOS updates, so check which BIOS version your board needs for a new CPU. TweakTown notes that boards with smaller 32MB BIOS chips have already hit space limits when supporting older CPUs.
Chipset tier
AMD hasn’t said which AM5 chipsets will support Zen 6. Don’t assume support from the chipset name alone.
✅ Do This: Before ordering any new AM5 processor, open your motherboard’s support page, find the CPU support list, and note the BIOS version listed for that CPU.
Buy now or wait for Zen 6 and Nova Lake?
The right choice depends on when you need the machine.
If you’re building now
- If you want a CPU upgrade later on the same board, AM5 is the platform with a published window.
- If you’ll keep your first CPU for the board’s life, LGA1851 still carries current chips; its upgrade path simply ends at 200S Plus.
If you already own a board
- AM5 owners: watch your board’s CPU support list for Zen 6 entries.
- LGA1851 owners: moving to Nova Lake means a new board. TechPowerUp reports LGA1954 is expected to keep cooler compatibility with LGA1851 and LGA1700, but confirm your exact cooler with its maker.
Common misreadings of socket support claims
Each of these headline shortcuts can lead to a wrong purchase.
“Supported through 2029” doesn’t mean a new CPU in 2029
AMD hasn’t named products or launch years, only the support window.
Socket support isn’t board support
Your board’s support list and BIOS decide what runs, as the three-point check shows.
Same cooler mount doesn’t mean same platform
A cooler that fits LGA1954 won’t make an LGA1851 board accept Nova Lake.
Frequently asked questions
1. How long is AM5 socket support?
AMD says AM5 socket support runs through 2029, a window it announced at Computex on May 31, 2026.
2. Will Zen 6 work on AM5?
AMD’s documentation lists Zen 6 Ryzen 10000 “Olympic Ridge” desktop CPUs as AM5-compatible, but no launch date or models are announced.
3. Will Zen 6 run on my B650 or A620 board?
That depends on your board maker releasing a supporting BIOS. Check the CPU support list on your exact model’s support page.
4. Is LGA1851 end of life?
Intel has issued no formal notice, but no CPUs beyond Core Ultra 200S Plus are announced, and Nova Lake-S is linked to LGA1954.
5. What socket will Nova Lake use?
Intel’s own Design-In Tools listing pairs Nova Lake-S with LGA1954, so Nova Lake will need a new motherboard.
6. Is AM5 or LGA1851 better for CPU upgrades?
AM5 has an official support window through 2029, while LGA1851 has no announced CPUs after the Core Ultra 200S Plus refresh.
7. Does “through 2029” mean new AM5 CPUs in 2029?
Not necessarily. AMD’s AM5 support window doesn’t name specific products or promise a launch in any particular year.
8. Do I need a BIOS update for a new AM5 CPU?
Usually yes. A newer AM5 CPU needs the BIOS version shown on your board’s CPU support list. Use only your board maker’s file and method, and contact their support if unsure.
9. Will my LGA1851 cooler fit LGA1954?
LGA1954 is reportedly expected to keep LGA1851 cooler compatibility. Confirm on your cooler maker’s compatibility page before reusing it.
10. Should I wait for Zen 6 or Nova Lake?
Wait only if you don’t need the PC before 2027. Neither Zen 6 desktop chips nor Nova Lake-S has an announced launch date.
Pick the platform that matches your upgrade plan
AM5 has an official window through 2029, while LGA1851’s announced path ends with Arrow Lake Refresh. Your next step is to open your board’s CPU support list before you buy any processor. For the full picture, review why socket match alone isn’t enough. If you’re choosing an Intel board, compare Z890, B860, and H810.
