Core i5-14400F + RX 6950 XT: bottleneck check

5%

Balanced at 1440p.

Well matched at 1440p. The RX 6950 XT is the slightly busier part, by about 5%.

This is the classic pattern: at 1080p the Core i5-14400F is the limit (3%), while at 4K the RX 6950 XT takes over (26% 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 RX 6950 XT measured 341 W average while gaming (445 W highest 20 ms spike, TechPowerUp). With the Core i5-14400F at its maximum turbo power of 148 W and about 75 W for the rest of the system, the sustained load is about 564 W. A 1000 W unit is the safe choice.
