Performance comparison: which is faster?
AMD EPYC 9554 (AMD, 2023) and AMD EPYC 7773X (AMD, 2022) 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 9554 is about 30% faster
The sockets differ (SP5 / SP3), so switching requires a motherboard replacement. 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 9554 | EPYC 7773X |
|---|---|---|
| Performance Score | 130,000 | 100,000 |
| Generation | EPYC | EPYC |
| Socket | SP5 | SP3 |
| Release Year | 2023 | 2022 |
| Type | Server | Server |
| Compatible GPU Example | Radeon RX 6700 XT | GeForce RTX 2080 SUPER |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | EPYC 9554 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | EPYC 7773X (the lower model is often sufficient) |
EPYC 9554 is about 30% higher by score (EPYC 9554: 130000 points / EPYC 7773X: 100000 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.The sockets differ (SP5 / SP3), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 6700 XT pairs well with EPYC 9554 and GeForce RTX 2080 SUPER pairs well with EPYC 7773X. If either GPU is too strong or too weak, one part holds the other back.
