Radeon RX Vega 56 vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: Radeon RX Vega 56 vs GeForce GTX 1660 SUPER
The Radeon RX Vega 56 is noticeably faster, around 9% ahead of the GeForce GTX 1660 SUPER. Both cards sit in the same broad class, well suited to entry-level 1080p.
Price & Value
On price, expect to pay $150 USD for the Radeon RX Vega 56 versus $155 USD for the GeForce GTX 1660 SUPER. Because it's both faster and competitively priced, the Radeon RX Vega 56 wins on performance-per-dollar by about 13%. The Radeon RX Vega 56 is trading below its $399 USD MSRP — a genuine deal. The GeForce GTX 1660 SUPER is trading below its $229 USD MSRP — a genuine deal.
Power & Efficiency
The GeForce GTX 1660 SUPER draws just 125W 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 SUPER's 6GB can fall short.
Generation & Longevity
The GeForce GTX 1660 SUPER 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 SUPER 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 SUPER or Radeon RX Vega 56?
The Radeon RX Vega 56 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce GTX 1660 SUPER if you find it at a steep discount.
