Performance comparison: which is faster?
AMD EPYC 7763 (AMD, 2021) and AMD Threadripper 3990X (AMD, 2020) 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 7763 is about 12.5% faster
The sockets differ (SP3 / sTRX4), 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 7763 | Threadripper 3990X |
|---|---|---|
| Performance Score | 90,000 | 80,000 |
| Generation | EPYC | Threadripper |
| Socket | SP3 | sTRX4 |
| Release Year | 2021 | 2020 |
| Type | Server | Server |
| Compatible GPU Example | Radeon RX 6650 XT | Radeon RX 6700 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | EPYC 7763 |
| Upgrade while reusing the current motherboard | Choose the CPU matching your motherboard socket |
| Prioritize value and adequate performance | Threadripper 3990X (the lower model is often sufficient) |
EPYC 7763 is about 12.5% higher by score (EPYC 7763: 90000 points / Threadripper 3990X: 80000 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.
EPYC 7763 is EPYC, while Threadripper 3990X is Threadripper.The sockets differ (SP3 / sTRX4), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, Radeon RX 6650 XT pairs well with EPYC 7763 and Radeon RX 6700 XT pairs well with Threadripper 3990X. If either GPU is too strong or too weak, one part holds the other back.
