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 $108 EUR against $313 EUR for the GeForce GTX 1660 SUPER. Despite being slower, the Radeon RX 580 offers the better performance-per-dollar (~58% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 580 is trading below its $229 EUR MSRP — a genuine deal. The GeForce GTX 1660 SUPER still sits about $84 EUR above its $229 EUR MSRP.

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?

Choose the GeForce GTX 1660 SUPER 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.

Frequently Asked Questions

Is the GeForce GTX 1660 SUPER better than the Radeon RX 580?

The GeForce GTX 1660 SUPER is dramatically faster, roughly 83% ahead. The Radeon RX 580 is still worth it if value matters more than top-end frames.

Which is better for 4K gaming, the Radeon RX 580 or the GeForce GTX 1660 SUPER?

Neither is a dedicated 4K card; both are best at entry-level 1080p. For 4K you'd want a faster GPU, or lean on upscaling.

Is the GeForce GTX 1660 SUPER worth the extra $205 EUR over the Radeon RX 580?

Only if you need the extra performance or features; on pure value the Radeon RX 580 comes out ahead.

Does the Radeon RX 580 have enough VRAM advantage to matter?

Its 8GB (vs 6GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
