Radeon RX 580 vs Radeon R9 380X: In-Depth Breakdown
Performance: Radeon RX 580 vs Radeon R9 380X
The Radeon RX 580 is dramatically faster, around 50% ahead of the Radeon R9 380X. Both cards sit in the same broad class, well suited to entry-level 1080p. The Radeon RX 580 packs 2,304 stream processors versus 2,048 on the Radeon R9 380X.
VRAM & Future-Proofing
With 8GB against 4GB, the Radeon RX 580 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon R9 380X's 4GB can fall short. The Radeon RX 580's memory is also faster — 256 GB/s versus 182 GB/s — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 580 is roughly 2 years newer than the Radeon R9 380X (GCN 4.0 (Polaris) vs GCN 3.0), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 580 or Radeon R9 380X?
The Radeon RX 580 is the faster card by about 50%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
