GeForce GTX 1080 Ti vs Radeon R9 390X: In-Depth Breakdown
Performance: GeForce GTX 1080 Ti vs Radeon R9 390X
The GeForce GTX 1080 Ti is dramatically faster, around 240% ahead of the Radeon R9 390X. That gap is enough to move it up a tier: the GeForce GTX 1080 Ti is comfortable at 1080p, while the Radeon R9 390X is better matched to entry-level 1080p.
Power & Efficiency
The GeForce GTX 1080 Ti draws just 250W 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 Pascal architecture on a TSMC 16nm process is part of why it does more with each watt.
VRAM & Future-Proofing
With 11GB against 8GB, the GeForce GTX 1080 Ti has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon R9 390X's 8GB can fall short.
Generation & Longevity
The GeForce GTX 1080 Ti is roughly 2 years newer than the Radeon R9 390X (Pascal 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 1080 Ti 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 1080 Ti or Radeon R9 390X?
The GeForce GTX 1080 Ti is the faster card by about 240%. 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.
