Radeon RX 590 vs Radeon R9 390X: In-Depth Breakdown
Performance: Radeon RX 590 vs Radeon R9 390X
The Radeon RX 590 is dramatically faster, around 40% ahead of the Radeon R9 390X. Both cards sit in the same broad class, well suited to entry-level 1080p.
Power & Efficiency
The Radeon RX 590 draws just 225W 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 12nm process is part of why it does more with each watt.
Memory & Bandwidth
The Radeon R9 390X's memory is faster — 384 GB/s versus 256 GB/s (512-bit vs 256-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Generation & Longevity
The Radeon RX 590 is roughly 3 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 R9 390X or Radeon RX 590?
The Radeon RX 590 is the faster card by about 40%. 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.
