Core i3-13100F + RTX 5070: bottleneck check

14%

CPU-limited at 1440p. Mild CPU bottleneck.

The Core i3-13100F cannot feed the RTX 5070 fast enough at 1440p, so the card sits partly idle in CPU-heavy games.

This is the classic pattern: at 1080p the Core i3-13100F is the limit (21%), while at 4K the RTX 5070 takes over (8% 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 5070 measured 229 W average while gaming (299 W highest 20 ms spike, TechPowerUp). With the Core i3-13100F at its maximum turbo power of 110 W and about 75 W for the rest of the system, the sustained load is about 414 W. A 650 W unit is the safe choice; a good-quality 550 W unit also covers the measured draw. Details on the RTX 5070 PSU page or try other pairs in the PSU calculator.
