Best CPU for the RX 6800
The AMD Radeon RX 6800 has a 1440p performance index of 37/100. To keep it busy a processor needs a gaming index of roughly 62 at 1440p and 68 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)

| 2 | Ryzen 7 5700X | AM4 | CPU 9% | CPU 0% | GPU 22% |
| 3 | Ryzen 5 5600X | AM4 | CPU 10% | CPU 2% | GPU 20% |
| 4 | Ryzen 5 8600G | AM5 | CPU 6% | GPU 3% | GPU 24% |
| 5 | Ryzen 7 5800X | AM4 | CPU 4% | GPU 4% | GPU 25% |
| 6 | Core i3-13100F | LGA1700 | CPU 12% | CPU 4% | GPU 19% |
| 7 | Ryzen 5 5600 | AM4 | CPU 12% | CPU 4% | GPU 19% |
| 8 | Core i5-12400F | LGA1700 | CPU 3% | GPU 6% | GPU 27% |
| 9 | Ryzen 9 5900X | AM4 | CPU 1% | GPU 7% | GPU 28% |
| 10 | Core i3-12100F | LGA1700 | CPU 15% | CPU 7% | GPU 16% |
Cheapest processor that avoids a bottleneck, per socket
- LGA1200: Core i5-11400F (gaming index 56, 6 cores)
- LGA1700: Core i3-12100F (gaming index 58, 4 cores)
- AM4: Ryzen 5 5600 (gaming index 60, 6 cores)
- AM5: Ryzen 5 8600G (gaming index 64, 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.
