Ceiling with a Ryzen 7 9800X3D and 32 GB

Will not run

This rig does not clear the minimum requirement.

Headroom: 22% short on GPU
Bottleneck: GPU
Confidence: estimated

Tier ladder

minimum blocked by GPU
recommended blocked by GPU
high blocked by GPU + VRAM
ultra blocked by GPU + VRAM

The weakest link is graphics card: this rig brings 7 against the 9 that Starfield asks for at the minimum tier. Everything else in the rig is already past that line.

That readout is the best this card can do in Starfield: it assumes nothing else in the machine holds it back. Your own processor and memory can only lower it, never raise it.

The same card with three different processors

In Starfield all three processors land the Radeon RX 580 8GB on the same tier - this pairing is decided by the card, not by what sits next to it. Each row assumes 16 GB of system memory.
