GeForce GTX TITAN X vs Radeon RX 6400: In-Depth Breakdown
Performance: GeForce GTX TITAN X vs Radeon RX 6400
The GeForce GTX TITAN X is dramatically faster, around 50% ahead of the Radeon RX 6400. Both cards sit in the same broad class, well suited to entry-level 1080p.
Power & Efficiency
At 53W against 250W, the Radeon RX 6400 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern RDNA 2 architecture on a TSMC N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce GTX TITAN X carries 12GB versus 4GB on the Radeon RX 6400. The extra 8GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The Radeon RX 6400 is roughly 7 years newer than the GeForce GTX TITAN X (RDNA 2 vs Maxwell), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce GTX TITAN X brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Radeon RX 6400 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 RX 6400?
The GeForce GTX TITAN X is the faster card by about 50%. 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.
