Radeon RX 570 vs Radeon R9 390: In-Depth Breakdown
Performance: Radeon RX 570 vs Radeon R9 390
The Radeon RX 570 is significantly faster, around 20% ahead of the Radeon R9 390. Both cards sit in the same broad class, well suited to entry-level 1080p.
Price & Value
Right now the Radeon RX 570 starts at $48,773 JPY against $98,846 JPY for the Radeon R9 390. Because it's both faster and competitively priced, the Radeon RX 570 wins on performance-per-dollar by about 143%. The Radeon RX 570 still sits about $48,604 JPY above its $169 JPY MSRP. The Radeon R9 390 still sits about $98,517 JPY above its $329 JPY MSRP.
Power & Efficiency
The Radeon RX 570 draws just 150W versus 275W for the Radeon R9 390, 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 390 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 390'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 390 (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 390 or Radeon RX 570?
The Radeon RX 570 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon R9 390 if you find it at a steep discount.
