GeForce GTX 1080 Ti vs Radeon R9 390: In-Depth Breakdown
Performance: GeForce GTX 1080 Ti vs Radeon R9 390
The GeForce GTX 1080 Ti is dramatically faster, around 240% ahead of the Radeon R9 390. That gap is enough to move it up a tier: the GeForce GTX 1080 Ti is comfortable at 1080p, while the Radeon R9 390 is better matched to entry-level 1080p.
Price & Value
Right now the Radeon R9 390 starts at $36 EUR against $798 EUR for the GeForce GTX 1080 Ti. Despite being slower, the Radeon R9 390 offers the better performance-per-dollar (~551% better value), so budget-focused buyers should weigh it carefully. The Radeon R9 390 is trading below its $329 EUR MSRP — a genuine deal. The GeForce GTX 1080 Ti still sits about $99 EUR above its $699 EUR MSRP.
Power & Efficiency
The GeForce GTX 1080 Ti draws just 250W versus 275W for the Radeon R9 390, 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 390's 8GB can fall short.
Generation & Longevity
The GeForce GTX 1080 Ti is roughly 2 years newer than the Radeon R9 390 (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 390 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 390?
Choose the GeForce GTX 1080 Ti if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon R9 390 stretches your money further for only slightly lower performance.
