Radeon R9 390X vs Radeon RX 570: In-Depth Breakdown
Performance: Radeon R9 390X vs Radeon RX 570
The Radeon R9 390X is noticeably faster, around 13% ahead of the Radeon RX 570. Both cards sit in the same broad class, well suited to entry-level 1080p. The Radeon R9 390X packs 2,816 stream processors versus 2,048 on the Radeon RX 570.
Power & Efficiency
The Radeon RX 570 draws just 150W versus 275W for the Radeon R9 390X, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern GCN 4.0 (Polaris) architecture on a GloFo 14nm process is part of why it does more with each watt.
VRAM & Future-Proofing
With 8GB against 4GB, the Radeon R9 390X has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 570's 4GB can fall short. The Radeon R9 390X's memory is also faster — 384 GB/s versus 224 GB/s (512-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 570 is roughly 2 years newer than the Radeon R9 390X (GCN 4.0 (Polaris) vs GCN 2.0), so it generally benefits from a more modern architecture and longer driver-support runway.
Which should you buy: Radeon RX 570 or Radeon R9 390X?
The Radeon R9 390X is the faster card by about 13%. 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.
