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 GeForce GTX TITAN Z currently lists from $33 EUR, $220 EUR less than the Radeon RX 6400 at $253 EUR. Despite being slower, the GeForce GTX TITAN Z offers the better performance-per-dollar (~545% better value), so budget-focused buyers should weigh it carefully. The GeForce GTX TITAN Z is trading below its $2,999 EUR MSRP — a genuine deal. The Radeon RX 6400 still sits about $94 EUR above its $159 EUR MSRP.
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
The GeForce GTX TITAN Z 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 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?
Choose the Radeon RX 6400 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX TITAN Z stretches your money further for only slightly lower performance.
