Will the Core i3-12100F bottleneck the RTX 4070 Ti Super?

Yes, at 1440p the Core i3-12100F is estimated to limit the RTX 4070 Ti Super by about 21%. The effect is larger at 1080p and smaller at 4K. This is a model estimate from performance indexes, not a measured FPS loss.

What power supply do I need for a Core i3-12100F and RTX 4070 Ti Super?

Sustained gaming load is about 458 W using the RTX 4070 Ti Super's measured draw. A 750 W unit is the safe choice; a good-quality 650 W unit also covers it.

Is this pair better at 1080p or 4K?

1080p: CPU-limited 27% (moderate CPU bottleneck). 1440p: CPU-limited 21% (mild CPU bottleneck). 4K: GPU-limited 0% (balanced).

Core i3-12100F + RTX 4070 Ti Super: bottleneck check

21%

CPU-limited at 1440p. Mild CPU bottleneck.

CPU GPU

The Core i3-12100F cannot feed the RTX 4070 Ti Super fast enough at 1440p, so the card sits partly idle in CPU-heavy games.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	CPU	27%	moderate CPU bottleneck
1440p	CPU	21%	mild CPU bottleneck
4K	GPU	0%	balanced

This is the classic pattern: at 1080p the Core i3-12100F is the limit (27%), while at 4K the RTX 4070 Ti Super takes over (0% 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 Super measured 294 W average while gaming (320 W highest 20 ms spike, TechPowerUp). With the Core i3-12100F at its maximum turbo power of 89 W and about 75 W for the rest of the system, the sustained load is about 458 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 Super PSU page or try other pairs in the PSU calculator.
