GeForce GTX 1660 SUPER vs Radeon RX 580: In-Depth Breakdown
Performance: GeForce GTX 1660 SUPER vs Radeon RX 580
The GeForce GTX 1660 SUPER is dramatically faster, around 83% ahead of the Radeon RX 580. Both cards sit in the same broad class, well suited to entry-level 1080p.
Price & Value
Right now the Radeon RX 580 starts at $127 GBP against $173 GBP for the GeForce GTX 1660 SUPER. Because it's both faster and competitively priced, the GeForce GTX 1660 SUPER wins on performance-per-dollar by about 34%. The Radeon RX 580 is trading below its $229 GBP MSRP — a genuine deal. The GeForce GTX 1660 SUPER is trading below its $229 GBP MSRP — a genuine deal.
Power & Efficiency
The GeForce GTX 1660 SUPER draws just 125W versus 185W for the Radeon RX 580, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Turing architecture on a TSMC 12nm process is part of why it does more with each watt.
VRAM & Future-Proofing
With 8GB against 6GB, the Radeon RX 580 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1660 SUPER's 6GB can fall short.
Generation & Longevity
The GeForce GTX 1660 SUPER is roughly 2 years newer than the Radeon RX 580 (Turing vs GCN 4.0 (Polaris)), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Radeon RX 580 brings AMD FSR upscaling and strong rasterization value, while the GeForce GTX 1660 SUPER offers NVIDIA DLSS upscaling/frame generation and stronger ray tracing. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: Radeon RX 580 or GeForce GTX 1660 SUPER?
The GeForce GTX 1660 SUPER 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 RX 580 if you find it at a steep discount.
