GeForce GTX TITAN Z vs Radeon R9 390X: In-Depth Breakdown

Performance: GeForce GTX TITAN Z vs Radeon R9 390X

The GeForce GTX TITAN Z and Radeon R9 390X post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to entry-level 1080p gaming.

Power & Efficiency

The Radeon R9 390X draws just 275W versus 375W for the GeForce GTX TITAN Z, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern GCN 2.0 architecture on a TSMC 28nm process is part of why it does more with each watt.

VRAM & Future-Proofing

With 12GB against 8GB, the GeForce GTX TITAN Z has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon R9 390X's 8GB can fall short.

Features & Ecosystem

Beyond raw numbers, the GeForce GTX TITAN Z 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 TITAN Z or Radeon R9 390X?

The GeForce GTX TITAN Z is the faster card. 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.

Frequently Asked Questions

Is the GeForce GTX TITAN Z better than the Radeon R9 390X?

They're very close on raw performance. Pick based on price, VRAM, and power draw rather than speed.

Which is better for 4K gaming, the GeForce GTX TITAN Z or the Radeon R9 390X?

Neither is a dedicated 4K card; both are best at entry-level 1080p. For 4K you'd want a faster GPU, or lean on upscaling.

Does the GeForce GTX TITAN Z have enough VRAM advantage to matter?

Its 12GB (vs 8GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
