Performance comparison: which is faster?
Xeon W9-3545 (Intel, 2023) and Xeon Gold 6354 (Intel, 2021) 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: Xeon W9-3545 is about 66.7% faster
The sockets differ (FCLGA4677 / LGA4189), 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 | Xeon W9-3545 | Xeon Gold 6354 |
|---|---|---|
| Performance Score | 70,000 | 42,000 |
| Generation | Xeon | Xeon |
| Socket | FCLGA4677 | LGA4189 |
| Release Year | 2023 | 2021 |
| Type | Server | Server |
| Compatible GPU Example | GeForce RTX 4070 | GeForce RTX 2080 SUPER |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Xeon W9-3545 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | Xeon Gold 6354 (the lower model is often sufficient) |
Xeon W9-3545 is about 66.7% higher by score (Xeon W9-3545: 70000 points / Xeon Gold 6354: 42000 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 Xeon-generation CPUs.The sockets differ (FCLGA4677 / LGA4189), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 4070 pairs well with Xeon W9-3545 and GeForce RTX 2080 SUPER pairs well with Xeon Gold 6354. If either GPU is too strong or too weak, one part holds the other back.
