GeForce GTX 1660 vs Radeon RX 580: In-Depth Breakdown
Performance: GeForce GTX 1660 vs Radeon RX 580
The GeForce GTX 1660 is dramatically faster, around 67% 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 $188 SGD against $613 SGD for the GeForce GTX 1660. Despite being slower, the Radeon RX 580 offers the better performance-per-dollar (~95% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 580 is trading below its $229 SGD MSRP — a genuine deal. The GeForce GTX 1660 still sits about $394 SGD above its $219 SGD MSRP.
Power & Efficiency
The GeForce GTX 1660 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) gives it more room for 4K textures and memory-hungry creative or AI workloads.
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?
Choose the GeForce GTX 1660 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 580 stretches your money further for only slightly lower performance.
