Best CPU for the RTX 4080 Super
The NVIDIA GeForce RTX 4080 Super has a 1440p performance index of 64/100. To keep it busy a processor needs a gaming index of roughly 78 at 1440p and 85 at 1080p; anything above that is headroom, anything far above is money better spent on the graphics card. Below: the processors that hit the sweet spot, then the cheapest safe pick on each socket.
Sweet-spot processors (1440p)
| # | CPU | Socket | 1080p | 1440p | 4K |
|---|---|---|---|---|---|
| 1 | Core i9-12900K | LGA1700 | CPU 8% | CPU 1% | GPU 21% |
| 2 | Core i5-13600K | LGA1700 | CPU 8% | CPU 1% | GPU 21% |
| 3 | Ryzen 7 5800X3D | AM4 | CPU 8% | CPU 1% | GPU 21% |
| 4 | Ryzen 7 7700 | AM5 | CPU 8% | CPU 1% | GPU 21% |
| 5 | Core i5-14600K | LGA1700 | CPU 6% | GPU 2% | GPU 22% |
| 6 | Core Ultra 7 265K | LGA1851 | CPU 6% | GPU 2% | GPU 22% |
| 7 | Ryzen 7 7700X | AM5 | CPU 6% | GPU 2% | GPU 22% |
| 8 | Ryzen 5 9600X | AM5 | CPU 6% | GPU 2% | GPU 22% |
| 9 | Ryzen 5 7600X | AM5 | CPU 9% | CPU 2% | GPU 19% |
| 10 | Ryzen 9 7900X | AM5 | CPU 4% | GPU 3% | GPU 23% |
Cheapest processor that avoids a bottleneck, per socket
- LGA1700: Core i5-12600K (gaming index 72, 10 cores)
- AM4: Ryzen 7 5700X3D (gaming index 74, 8 cores)
- AM5: Ryzen 5 7600 (gaming index 75, 6 cores)
- LGA1851: Core Ultra 5 245K (gaming index 76, 14 cores)
If you already own a motherboard, start from its socket. AM4 and LGA1700 are end-of-line but cheap; AM5 and LGA1851 leave an upgrade path for the next GPU.
