Ryzen 7 3700X + RTX 3070 Ti: bottleneck check

16%

CPU-limited at 1440p. Mild CPU bottleneck.

The Ryzen 7 3700X cannot feed the RTX 3070 Ti fast enough at 1440p, so the card sits partly idle in CPU-heavy games.

This is the classic pattern: at 1080p the Ryzen 7 3700X is the limit (23%), while at 4K the RTX 3070 Ti 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 3070 Ti measured 298 W average while gaming (350 W highest 20 ms spike, TechPowerUp). With the Ryzen 7 3700X at a power figure of 65 W and about 75 W for the rest of the system, the sustained load is about 438 W. A 750 W unit is the safe choice; a good-quality 650 W unit also covers the measured draw. Details on the RTX 3070 Ti PSU page or try other pairs in the PSU calculator.
