The RTX 4070 Ti is powerful enough that at 1080p, most CPUs will create some bottleneck. At 1440p, the GPU does more work and bottlenecks are less common.

Resolution Considerations

Your target resolution should heavily influence your CPU choice:

1. 1080p Gaming: You need a powerful CPU. The 9800X3D, 7800X3D, or 14700K are ideal. Budget options like the 13600K will create some bottlenecks in CPU-intensive games.
2. 1440p Gaming: The sweet spot for RTX 4070 Ti. Most CPUs on this list perform well here. Even budget options like the 12700KF deliver great performance.
3. 4K Gaming: The GPU does almost all the work. Even budget CPUs won’t bottleneck significantly, though faster CPUs still provide better 1% lows.

Platform Costs Matter

Don’t forget that the CPU is just part of the equation:

• Intel Platforms: LGA1700 supports both DDR4 (cheaper) and DDR5 (more expensive). Motherboards are generally less expensive than AM5.
• AMD Platforms: AM5 requires DDR5 memory and typically more expensive motherboards, but offers upgrade paths until 2027.
• Total Cost: An AM5 build might cost $200-300 more total due to platform requirements.
