Radeon RX Vega 64 vs GeForce GTX 1660 Ti: In-Depth Breakdown
Performance: Radeon RX Vega 64 vs GeForce GTX 1660 Ti
The Radeon RX Vega 64 is significantly faster, around 27% ahead of the GeForce GTX 1660 Ti. That gap is enough to move it up a tier: the Radeon RX Vega 64 is comfortable at 1080p, while the GeForce GTX 1660 Ti is better matched to entry-level 1080p.
Price & Value
The GeForce GTX 1660 Ti currently lists from $780 AED, $2,430 AED less than the Radeon RX Vega 64 at $3,210 AED. Despite being slower, the GeForce GTX 1660 Ti offers the better performance-per-dollar (~223% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 Ti still sits about $501 AED above its $279 AED MSRP. The Radeon RX Vega 64 still sits about $2,711 AED above its $499 AED MSRP.
Power & Efficiency
At 120W against 295W, the GeForce GTX 1660 Ti 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
The Radeon RX Vega 64 carries 8GB versus 6GB on the GeForce GTX 1660 Ti. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The GeForce GTX 1660 Ti 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 Ti 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 Ti or Radeon RX Vega 64?
Choose the Radeon RX Vega 64 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1660 Ti stretches your money further for only slightly lower performance.
