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 $775 AED against $1,714 AED for the Radeon RX Vega 56. Despite being slower, the GeForce GTX 1660 offers the better performance-per-dollar (~84% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 still sits about $556 AED above its $219 AED MSRP. The Radeon RX Vega 56 still sits about $1,315 AED above its $399 AED MSRP.
Power & Efficiency
The GeForce GTX 1660 sips power at 120W next to the Radeon RX Vega 56's 210W, 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 Vega 56'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 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.
