Will the Core i7-10700K bottleneck the RX 6800?

Only slightly: at 1440p the model puts the Core i7-10700K about 7% short of keeping the RX 6800 fully fed, which is within the balanced band. The gap grows at 1080p and closes at 4K. This is a model estimate from performance indexes, not a measured FPS loss.

What power supply do I need for a Core i7-10700K and RX 6800?

Sustained gaming load is about 435 W using the RX 6800's measured draw. A 650 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: CPU-limited 15% (mild CPU bottleneck). 1440p: CPU-limited 7% (balanced). 4K: GPU-limited 16% (balanced).

Core i7-10700K + RX 6800: bottleneck check

Balanced at 1440p.

CPU GPU

Well matched at 1440p. The Core i7-10700K is the slightly busier part, by about 7%.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	CPU	15%	mild CPU bottleneck
1440p	CPU	7%	balanced
4K	GPU	16%	balanced

This is the classic pattern: at 1080p the Core i7-10700K is the limit (15%), while at 4K the RX 6800 takes over (16% 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 measured 235 W average while gaming (344 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 435 W. A 650 W unit is the safe choice.
