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 Radeon RX 580 starts at $180 against $395 for the GeForce GTX 1660. Despite being slower, the Radeon RX 580 offers the better performance-per-dollar (~80% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 580 is trading below its $229 MSRP — a genuine deal. The GeForce GTX 1660 still sits about $176 above its $219 MSRP.

Power & Efficiency

The GeForce GTX 1660 draws just 120W 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.

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, 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.

Frequently Asked Questions

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

The GeForce GTX 1660 is significantly faster, roughly 22% ahead. The Radeon RX 580 is still worth it if value matters more than top-end frames.

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

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 worth the extra $215 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.
