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
On price, expect to pay $161 EUR for the Radeon RX 580 versus $249 EUR 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 19%. The Radeon RX 580 is trading below its $229 EUR 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 GeForce GTX 1660 SUPER brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 580 offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce GTX 1660 SUPER or Radeon RX 580?
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.
