Core i7-10700K + RX 6800 XT: bottleneck check

11%

CPU-limited at 1440p. Mild CPU bottleneck.

The Core i7-10700K cannot feed the RX 6800 XT fast enough at 1440p, so the card sits partly idle in CPU-heavy games.

This is the classic pattern: at 1080p the Core i7-10700K is the limit (18%), while at 4K the RX 6800 XT takes over (12% 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 6800 XT measured 298 W average while gaming (579 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 498 W. A 850 W unit is the safe choice.
