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 27% ahead of the GeForce GTX 1660. That gap is enough to move it up a tier: the Radeon RX Vega 56 is comfortable at 1080p, while the GeForce GTX 1660 is better matched to entry-level 1080p.
Price & Value
Right now the GeForce GTX 1660 starts at $59 GBP against $486 GBP for the Radeon RX Vega 56. Despite being slower, the GeForce GTX 1660 offers the better performance-per-dollar (~548% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 is trading below its $219 GBP MSRP — a genuine deal. The Radeon RX Vega 56 still sits about $87 GBP above its $399 GBP 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.
