Performance comparison: which is faster?
AMD EPYC 9654 (AMD, 2023) and AMD EPYC 9554 (AMD, 2023) are compared here. Compare not only scores, but also whether the motherboard can be reused and which GPU class is balanced with each CPU.
Overall performance: EPYC 9654 is about 19.2% faster
Both use the same SP5 socket, so they can be installed on the same motherboard. For games, performance balance with the GPU (guideline CPU:GPU = 0.9:1) matters more than CPU speed alone.
Relative performance score (higher is faster). Actual speed varies by workload, cooling, and memory configuration.
| Item | EPYC 9654 | EPYC 9554 |
|---|---|---|
| Performance Score | 155,000 | 130,000 |
| Generation | EPYC | EPYC |
| Socket | SP5 | SP5 |
| Release Year | 2023 | 2023 |
| Type | Server | Server |
| Compatible GPU Example | Radeon RX 6700 XT | Radeon RX 6700 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | EPYC 9654 |
| Upgrade while reusing the current motherboard | Either works (same SP5 socket) |
| Prioritize value and adequate performance | EPYC 9554 (the lower model is often sufficient) |
EPYC 9654 is about 19.2% higher by score (EPYC 9654: 155000 points / EPYC 9554: 130000 points). For gaming, the GPU tier usually matters more than a few percent of CPU difference. For CPU-heavy work such as video editing and streaming, choose the faster CPU.
Both are EPYC-generation CPUs.Both use the same SP5 socket, so they can be installed on the same motherboard.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 6700 XT pairs well with EPYC 9654 and Radeon RX 6700 XT pairs well with EPYC 9554. If either GPU is too strong or too weak, one part holds the other back.
