Radeon RX 6400 vs GeForce GTX TITAN Z: In-Depth Breakdown
Performance: Radeon RX 6400 vs GeForce GTX TITAN Z
The Radeon RX 6400 is significantly faster, around 20% ahead of the GeForce GTX TITAN Z. Both cards sit in the same broad class, well suited to entry-level 1080p.
Price & Value
The Radeon RX 6400 currently lists from $178 USD, $421 USD less than the GeForce GTX TITAN Z at $599 USD. Because it's both faster and competitively priced, the Radeon RX 6400 wins on performance-per-dollar by about 304%. The GeForce GTX TITAN Z is trading below its $2,999 USD MSRP — a genuine deal.
Power & Efficiency
At 53W against 375W, 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
VRAM favors the GeForce GTX TITAN Z at 12GB versus 4GB on the Radeon RX 6400 — that extra 8GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work.
Generation & Longevity
The Radeon RX 6400 is roughly 8 years newer than the GeForce GTX TITAN Z (RDNA 2 vs Kepler), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce GTX TITAN Z 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 Z or Radeon RX 6400?
The Radeon RX 6400 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce GTX TITAN Z if you find it at a steep discount.
