Core i7-10700K + RTX 4070 Super: bottleneck check

16%

CPU-limited at 1440p. Mild CPU bottleneck.

The Core i7-10700K cannot feed the RTX 4070 Super fast enough at 1440p, so the card sits partly idle in CPU-heavy games.

This is the classic pattern: at 1080p the Core i7-10700K is the limit (23%), while at 4K the RTX 4070 Super takes over (6% 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 Super measured 218 W average while gaming (239 W highest 20 ms spike, TechPowerUp). With the Core i7-10700K at its TDP of 125 W and about 75 W for the rest of the system, the sustained load is about 418 W. A 650 W unit is the safe choice.
