Will the Ryzen 5 3600 bottleneck the RX 9070 XT?

Yes, at 1440p the Ryzen 5 3600 is estimated to limit the RX 9070 XT by about 37%. The effect is larger at 1080p and smaller at 4K. This is a model estimate from performance indexes, not a measured FPS loss.

What power supply do I need for a Ryzen 5 3600 and RX 9070 XT?

Sustained gaming load is about 454 W using the RX 9070 XT's measured draw. A 750 W unit is the safe choice.

Is this pair better at 1080p or 4K?

1080p: CPU-limited 42% (severe CPU bottleneck). 1440p: CPU-limited 37% (moderate CPU bottleneck). 4K: CPU-limited 20% (mild CPU bottleneck).

Ryzen 5 3600 + RX 9070 XT: bottleneck check

37%

CPU-limited at 1440p. Moderate CPU bottleneck.

CPU GPU

The Ryzen 5 3600 cannot feed the RX 9070 XT fast enough at 1440p, so the card sits partly idle in CPU-heavy games.

By resolution

Resolution	Limiting part	Severity	Verdict
1080p	CPU	42%	severe CPU bottleneck
1440p	CPU	37%	moderate CPU bottleneck
4K	CPU	20%	mild CPU bottleneck

The Ryzen 5 3600 is the limiting part at every resolution, even at 4K (20%). The RX 9070 XT is a much stronger card than this processor can drive — plan a CPU upgrade before spending more on graphics.

Power supply

The RX 9070 XT measured 314 W average while gaming (390 W highest 20 ms spike, TechPowerUp). With the Ryzen 5 3600 at a power figure of 65 W and about 75 W for the rest of the system, the sustained load is about 454 W. A 750 W unit is the safe choice.
