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.
Price & Value
Pricing has the Radeon RX 6400 at $178 USD, $12 USD under the GeForce GTX TITAN X's $190 USD. Because it's both faster and competitively priced, the GeForce GTX TITAN X wins on performance-per-dollar by about 41%. The GeForce GTX TITAN X is trading below its $999 USD MSRP — a genuine deal.
Power & Efficiency
Power draw favors the Radeon RX 6400 (53W vs 250W), and it's the more efficient card too, so it's the easy pick if thermals or a smaller PSU matter. 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 all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Radeon RX 6400 if you find it at a steep discount.
