Radeon RX Vega 64 vs GeForce GTX 1660: In-Depth Breakdown
Performance: Radeon RX Vega 64 vs GeForce GTX 1660
The Radeon RX Vega 64 is dramatically faster, around 40% ahead of the GeForce GTX 1660. That gap is enough to move it up a tier: the Radeon RX Vega 64 is comfortable at 1080p, while the GeForce GTX 1660 is better matched to entry-level 1080p.
Price & Value
The GeForce GTX 1660 currently lists from $11,389 JPY, $129,053 JPY less than the Radeon RX Vega 64 at $140,442 JPY. Despite being slower, the GeForce GTX 1660 offers the better performance-per-dollar (~781% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX 1660 still sits about $11,170 JPY above its $219 JPY MSRP. The Radeon RX Vega 64 still sits about $139,943 JPY above its $499 JPY MSRP.
Power & Efficiency
At 120W against 295W, the GeForce GTX 1660 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. 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 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 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 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 stretches your money further for only slightly lower performance.
