Performance comparison: which is faster?
AMD Threadripper PRO 5975WX (AMD, 2022) 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: Threadripper PRO 5975WX is about 6.3% faster
The sockets differ (sWRX8 / 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 | Threadripper PRO 5975WX | Threadripper 3990X |
|---|---|---|
| Performance Score | 85,000 | 80,000 |
| Generation | Threadripper | Threadripper |
| Socket | sWRX8 | sTRX4 |
| Release Year | 2022 | 2020 |
| Type | Server | Server |
| Compatible GPU Example | GeForce RTX 5060 | Radeon RX 6700 XT |
| If You Want To... | Recommended |
|---|---|
| Prioritize maximum speed for heavy work or a high-end GPU | Threadripper PRO 5975WX |
| 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) |
Threadripper PRO 5975WX is about 6.3% higher by score (Threadripper PRO 5975WX: 85000 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.
Both are Threadripper-generation CPUs.The sockets differ (sWRX8 / sTRX4), so switching requires a motherboard replacement.
Using our CPU:GPU = 0.9:1 guideline, GeForce RTX 5060 pairs well with Threadripper PRO 5975WX 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.
