Core i7-11700K + RTX 4070 Ti: bottleneck check

13%

CPU-limited at 1440p. Mild CPU bottleneck.

The Core i7-11700K cannot feed the RTX 4070 Ti fast enough at 1440p, so the card sits partly idle in CPU-heavy games.

This is the classic pattern: at 1080p the Core i7-11700K is the limit (20%), while at 4K the RTX 4070 Ti takes over (10% GPU-limited). If you play at 1080p on a high-refresh monitor, a faster CPU is the upgrade that matters; at 1440p or 4K this pair is already well matched.

Power supply

The RTX 4070 Ti measured 273 W average while gaming (326 W highest 20 ms spike, TechPowerUp). With the Core i7-11700K at its TDP of 125 W and about 75 W for the rest of the system, the sustained load is about 473 W. A 750 W unit is the safe choice; a good-quality 650 W unit also covers the measured draw. Details on the RTX 4070 Ti PSU page or try other pairs in the PSU calculator.
