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 R9 390 starts at $2,076 AED against $3,148 AED for the Radeon RX 570. Despite being slower, the Radeon R9 390 offers the better performance-per-dollar (~26% better value), so budget-focused buyers should weigh it carefully. The Radeon R9 390 still sits about $1,747 AED above its $329 AED MSRP. The Radeon RX 570 still sits about $2,979 AED above its $169 AED MSRP.
Power & Efficiency
The Radeon RX 570 sips power at 150W next to the Radeon R9 390's 275W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. 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
The Radeon R9 390's 8GB (vs 4GB on the Radeon RX 570) gives it more room for 4K textures and memory-hungry creative or AI workloads. 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?
Choose the Radeon RX 570 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon R9 390 stretches your money further for only slightly lower performance.
