GeForce GTX 1660 vs Radeon RX 580: In-Depth Breakdown

Performance: GeForce GTX 1660 vs Radeon RX 580

The GeForce GTX 1660 is significantly faster, around 22% 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 GeForce GTX 1660 starts at $59 GBP against $137 GBP for the Radeon RX 580. Because it's both faster and competitively priced, the GeForce GTX 1660 wins on performance-per-dollar by about 184%. The GeForce GTX 1660 is trading below its $219 GBP MSRP β€” a genuine deal. The Radeon RX 580 is trading below its $229 GBP MSRP β€” a genuine deal.

Power & Efficiency

The GeForce GTX 1660 draws just 120W versus 185W for the Radeon RX 580, and it also delivers more performance per watt β€” 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's 6GB can fall short.

Generation & Longevity

The GeForce GTX 1660 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 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 or Radeon RX 580?

The GeForce GTX 1660 is the all-round winner here β€” 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.
