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

Performance: GeForce GTX TITAN X vs Radeon R9 390X

The GeForce GTX TITAN X is dramatically faster, around 80% 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 TITAN X sips power at 250W next to the Radeon R9 390X's 275W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU.

VRAM & Future-Proofing

The GeForce GTX TITAN X's 12GB (vs 8GB on the Radeon R9 390X) gives it more room for 4K textures and memory-hungry creative or AI workloads.

Features & Ecosystem

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

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.

Frequently Asked Questions

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

The GeForce GTX TITAN X is dramatically faster, roughly 80% ahead. If your budget allows, it's the stronger pick.

Which is better for 4K gaming, the GeForce GTX TITAN X 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 X 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.
