GeForce GTX TITAN X vs Radeon R9 390: In-Depth Breakdown
Performance: GeForce GTX TITAN X vs Radeon R9 390
The GeForce GTX TITAN X is dramatically faster, around 80% ahead of the Radeon R9 390. Both cards sit in the same broad class, well suited to entry-level 1080p.
Power & Efficiency
The GeForce GTX TITAN X 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.
VRAM & Future-Proofing
With 12GB against 8GB, the GeForce GTX TITAN X has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon R9 390's 8GB can fall short.
Features & Ecosystem
Beyond raw numbers, the GeForce GTX TITAN X 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 TITAN X or Radeon R9 390?
The GeForce GTX TITAN X is the faster card by about 80%. 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.
