Radeon RX Vega 56 vs GeForce GTX 1660: In-Depth Breakdown

Performance: Radeon RX Vega 56 vs GeForce GTX 1660

The Radeon RX Vega 56 is significantly faster, around 20% ahead of the GeForce GTX 1660. Both cards sit in the same broad class, well suited to entry-level 1080p.

Price & Value

Right now the GeForce GTX 1660 starts at $230 EUR against $790 EUR for the Radeon RX Vega 56. Despite being slower, the GeForce GTX 1660 offers the better performance-per-dollar (~186% better value), so budget-focused buyers should weigh it carefully. The Radeon RX Vega 56 still sits about $391 EUR above its $399 EUR MSRP.

Power & Efficiency

The GeForce GTX 1660 draws just 120W versus 210W for the Radeon RX Vega 56, 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 Vega 56 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 Vega 56 (Turing vs GCN 5.0 (Vega)), 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 Vega 56 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 Vega 56?

Choose the Radeon RX Vega 56 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1660 stretches your money further for only slightly lower performance.

Frequently Asked Questions

Is the Radeon RX Vega 56 better than the GeForce GTX 1660?

The Radeon RX Vega 56 is significantly faster, roughly 20% ahead. The GeForce GTX 1660 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 Vega 56?

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 Radeon RX Vega 56 worth the extra $560 EUR over the GeForce GTX 1660?

Only if you need the extra performance or features; on pure value the GeForce GTX 1660 comes out ahead.

Does the Radeon RX Vega 56 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.
