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

The GeForce GTX TITAN X currently lists from $200 USD, $122 USD less than the Radeon RX 6400 at $322 USD. Because it's both faster and competitively priced, the GeForce GTX TITAN X wins on performance-per-dollar by about 142%. The GeForce GTX TITAN X is trading below its $999 USD MSRP — a genuine deal. The Radeon RX 6400 still sits about $163 USD above its $159 USD MSRP.

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 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.

Frequently Asked Questions

Is the GeForce GTX TITAN X better than the Radeon RX 6400?

The GeForce GTX TITAN X is dramatically faster, roughly 50% ahead. If your budget allows, it's the stronger pick.

Which is better for 4K gaming, the GeForce GTX TITAN X or the Radeon RX 6400?

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.

Is the Radeon RX 6400 worth the extra $122 USD over the GeForce GTX TITAN X?

Only if you need the extra performance or features; on pure value the GeForce GTX TITAN X comes out ahead.

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

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