Radeon RX Vega 64 vs GeForce GTX 1660 SUPER: In-Depth Breakdown
Performance: Radeon RX Vega 64 vs GeForce GTX 1660 SUPER
The Radeon RX Vega 64 is significantly faster, around 27% ahead of the GeForce GTX 1660 SUPER. That gap is enough to move it up a tier: the Radeon RX Vega 64 is comfortable at 1080p, while the GeForce GTX 1660 SUPER is better matched to entry-level 1080p.
Price & Value
The Radeon RX Vega 64 currently lists from $150 USD, $5 USD less than the GeForce GTX 1660 SUPER at $155 USD. Because it's both faster and competitively priced, the Radeon RX Vega 64 wins on performance-per-dollar by about 32%. The Radeon RX Vega 64 is trading below its $499 USD MSRP — a genuine deal. The GeForce GTX 1660 SUPER is trading below its $229 USD MSRP — a genuine deal.
Power & Efficiency
At 125W against 295W, the GeForce GTX 1660 SUPER is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Turing architecture on a TSMC 12nm process is part of why it does more with each watt.
VRAM & Future-Proofing
VRAM favors the Radeon RX Vega 64 at 8GB versus 6GB on the GeForce GTX 1660 SUPER — that extra 2GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work.
Generation & Longevity
The GeForce GTX 1660 SUPER is roughly 2 years newer than the Radeon RX Vega 64 (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 64 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 64?
The Radeon RX Vega 64 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.
