Will the Ryzen 7 5700X3D bottleneck the RX 6700 XT?

No. At 1440p the RX 6700 XT is the limiting part, which is the normal state for a gaming PC. The Ryzen 7 5700X3D has headroom to spare. This is a model estimate from performance indexes, not a measured FPS loss.

What power supply do I need for a Ryzen 7 5700X3D and RX 6700 XT?

Sustained gaming load is about 401 W using the RX 6700 XT's measured draw. A 650 W unit is the safe choice; a good-quality 550 W unit also covers it.

Is this pair better at 1080p or 4K?

1080p: GPU-limited 13% (balanced). 1440p: GPU-limited 21% (GPU-bound (normal)). 4K: GPU-limited 39% (GPU-bound (normal)).

Ryzen 7 5700X3D + RX 6700 XT: bottleneck check

21%

GPU-limited at 1440p. GPU-bound (normal).

CPU GPU

The RX 6700 XT is the part working hardest at 1440p, which is what you want. The Ryzen 7 5700X3D keeps about 21% in reserve.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	GPU	13%	balanced
1440p	GPU	21%	GPU-bound (normal)
4K	GPU	39%	GPU-bound (normal)

The RX 6700 XT is the limiting part at every resolution, which is the healthy direction, and the gap is small enough that neither part is wasted. Upgrade the GPU first when you want more frames.

Power supply

The RX 6700 XT measured 221 W average while gaming (321 W highest 20 ms spike, TechPowerUp). With the Ryzen 7 5700X3D at a power figure of 105 W and about 75 W for the rest of the system, the sustained load is about 401 W. A 650 W unit is the safe choice; a good-quality 550 W unit also covers the measured draw. Details on the RX 6700 XT PSU page or try other pairs in the PSU calculator.
