GeForce GTX 1660 Ti vs Radeon RX 580: In-Depth Breakdown
Performance: GeForce GTX 1660 Ti vs Radeon RX 580
The GeForce GTX 1660 Ti 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 $714 AED against $799 AED for the GeForce GTX 1660 Ti. Because it's both faster and competitively priced, the GeForce GTX 1660 Ti wins on performance-per-dollar by about 64%. The Radeon RX 580 still sits about $485 AED above its $229 AED MSRP. The GeForce GTX 1660 Ti still sits about $520 AED above its $279 AED MSRP.
Power & Efficiency
The GeForce GTX 1660 Ti sips power at 120W next to the Radeon RX 580's 185W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern Turing architecture on a TSMC 12nm process is part of why it does more with each watt.
VRAM & Future-Proofing
The Radeon RX 580's 8GB (vs 6GB on the GeForce GTX 1660 Ti) gives it more room for 4K textures and memory-hungry creative or AI workloads.
Generation & Longevity
The GeForce GTX 1660 Ti 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 Ti 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 Ti or Radeon RX 580?
The GeForce GTX 1660 Ti 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.
