EPYC 9655 vs EPYC 9654
The EPYC 9655 and the EPYC 9654 are both server processors we supply tested from Hong Kong, and the figures below are the same ones published on each product page. They share 2 listed specification rows and separate on socket, tdp, memory, so the decision is less about "which is better" and more about which of those differences your platform or workload can actually use.
Nothing on this page is a price: component pricing moved too fast in 2026 for a printed figure to stay honest, so both are quoted on request against confirmed stock with the date the quote holds until. If you are replacing a part, send the platform and we will confirm the population before you commit.

Rows that differ are highlighted. Figures are the same ones published on each product page; where a figure is community-sourced rather than vendor-published it is stated on that page. Confirm every part against your build sheet when ordering.
Where they differ
- ·Socket — EPYC 9655: SP5 (LGA6096); EPYC 9654: SP5 (LGA 6096).
- ·EPYC 9654 is the better figure for power draw (400W vs 360W (configurable)).
- ·Memory — EPYC 9655: 12-channel DDR5-6000, ECC, up to 6TB per socket; EPYC 9654: 12-channel DDR5-4800.
- ·PCIe — EPYC 9655: PCIe 5.0, 128 lanes (160 in 2-socket); EPYC 9654: PCIe Gen5, 128 lanes.
- ·EPYC 9655 lists the higher base clock (2.5GHz base / up to 4.5GHz max vs 2.4GHz base / 3.7GHz max boost).
What they share
Cores / Threads: 96 cores / 192 threads; Cache: 384MB L3.
Decision
Which one to buy
For processors the useful split is throughput versus frequency. More cores per socket wins on virtualisation density, parallel batch work and multi-tenant hosting, where the scheduler can keep every core busy; higher base and boost clocks win where the workload is latency-sensitive or licensed per core, and the extra cores would sit idle. Check the socket and the platform's memory generation before anything else: a CPU is only useful in a board that takes it, and the two models above are interchangeable only when the socket matches. TDP also sets the cooling and power budget per node.
Choose the EPYC 9655 if
- ·Socket: SP5 (LGA6096)
- ·Memory: 12-channel DDR5-6000, ECC, up to 6TB per socket
- ·PCIe: PCIe 5.0, 128 lanes (160 in 2-socket)
Choose the EPYC 9654 if
- ·Socket: SP5 (LGA 6096)
- ·You need lower power draw — the EPYC 9654 lists 360W (configurable) against 400W on the EPYC 9655.
- ·Memory: 12-channel DDR5-4800

Frequently asked questions
How much do the EPYC 9655 and the EPYC 9654 cost?
We do not publish prices for either: DRAM and CPU pricing moved too fast in 2026 for a printed figure to stay honest. Send the quantity, the platform and the condition you want and we quote both against confirmed stock, with the date the figure holds until.
What is the main difference between the EPYC 9655 and the EPYC 9654?
Socket (EPYC 9655: SP5 (LGA6096); EPYC 9654: SP5 (LGA 6096)); TDP (EPYC 9655: 400W; EPYC 9654: 360W (configurable)); Memory (EPYC 9655: 12-channel DDR5-6000, ECC, up to 6TB per socket; EPYC 9654: 12-channel DDR5-4800).
Can I use the EPYC 9655 and the EPYC 9654 in the same system?
Both are SP5 (LGA6096) parts, so one server can take either model — but you would not mix two different CPU models in a single two-socket machine; order one model per server.
Which one should I buy?
Buy the one whose strong points match the job: see the "Choose" section above. If you are replacing an existing part, send the platform or the old part number and we will confirm compatibility before you order.
What condition are they in, and do you ship worldwide?
Both are supplied tested with a 1-year written warranty. Condition is stated line by line before you order — new, decommissioned pull or OEM tray — and we ship worldwide from the Hong Kong warehouse with full export documentation, typically 3–7 days by air.
