Quick Answer
No, the i5-14600K does not bottleneck the RTX 4070 Super. This 14-core CPU (6P+8E) with 5.3 GHz boost is essentially a slightly faster i5-13600K and handles any current gaming GPU without issues. You will see GPU-limited performance at all resolutions.
The i5-14600K and RTX 4070 Super is one of the most popular high-performance gaming combinations in 2026. This pairing delivers excellent 1440p performance with room for future GPU upgrades.
1440p Results (the sweet spot):
At 1440p, the i5-14600K typically runs at 30-50% utilization while gaming. The RTX 4070 Super hits 95-100%. This confirms the GPU is the limiting factor, not the CPU. You could upgrade to an RTX 4080 or even a next-gen GPU without needing a new CPU.
The 14600K is essentially a refined 13600K with slightly higher clocks. In gaming, the difference is 1-3%. If you can find the 13600K cheaper, it is equally good for the RTX 4070 Super.
Pair with a Z790 motherboard if you want to overclock, or B760 to save money. Use 32GB DDR5-5600 RAM for optimal performance. A 750W PSU handles this combo with headroom.
Our Verdict
The i5-14600K and RTX 4070 Super is a near-perfect gaming pairing. Zero bottleneck with significant CPU headroom for GPU upgrades. This is the build to recommend for anyone wanting great 1440p performance without overspending.
