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.
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.
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, 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 faster card by about 22%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.
