Radeon RX Vega 56 vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: Radeon RX Vega 56 vs GeForce GTX 1660 Ti
The Radeon RX Vega 56 is noticeably faster, around 9% ahead of the GeForce GTX 1660 Ti. Both cards sit in the same broad class, well suited to entry-level 1080p.
Price & Value
Right now the Radeon RX Vega 56 starts at $27 EUR against $465 EUR for the GeForce GTX 1660 Ti. Because it's both faster and competitively priced, the Radeon RX Vega 56 wins on performance-per-dollar by about 1762%. The Radeon RX Vega 56 is trading below its $399 EUR MSRP — a genuine deal. The GeForce GTX 1660 Ti still sits about $186 EUR above its $279 EUR MSRP.
Power & Efficiency
The GeForce GTX 1660 Ti 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 Ti's 6GB can fall short.
Generation & Longevity
The GeForce GTX 1660 Ti 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 Ti 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 Ti 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 Ti if you find it at a steep discount.
