GeForce GTX 1660 vs Radeon R9 390X: In-Depth Breakdown
Performance: GeForce GTX 1660 vs Radeon R9 390X
The GeForce GTX 1660 is significantly faster, around 22% ahead of the Radeon R9 390X. Both cards sit in the same broad class, well suited to entry-level 1080p.
Price & Value
Right now the GeForce GTX 1660 starts at $70 EUR against $103 EUR for the Radeon R9 390X. Because it's both faster and competitively priced, the GeForce GTX 1660 wins on performance-per-dollar by about 80%. The GeForce GTX 1660 is trading below its $219 EUR MSRP — a genuine deal. The Radeon R9 390X is trading below its $429 EUR MSRP — a genuine deal.
Power & Efficiency
The GeForce GTX 1660 draws just 120W versus 275W for the Radeon R9 390X, 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 R9 390X has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1660's 6GB can fall short.
Generation & Longevity
The GeForce GTX 1660 is roughly 4 years newer than the Radeon R9 390X (Turing vs GCN 2.0), 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 R9 390X 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 R9 390X?
The GeForce GTX 1660 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon R9 390X if you find it at a steep discount.
