Core i7-10700K + RX 5700 XT: bottleneck check

7%

Balanced at 1440p.

Well matched at 1440p. The RX 5700 XT is the slightly busier part, by about 7%.

This is the classic pattern: at 1080p the Core i7-10700K is the limit (2%), while at 4K the RX 5700 XT takes over (28% 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 5700 XT measured 215 W average while gaming (266 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 415 W. A 650 W unit is the safe choice.
