Radeon RX 6400 vs GeForce GTX TITAN: In-Depth Breakdown
Performance: Radeon RX 6400 vs GeForce GTX TITAN
The Radeon RX 6400 is significantly faster, around 20% ahead of the GeForce GTX TITAN. Both cards sit in the same broad class, well suited to entry-level 1080p.
Price & Value
Right now the GeForce GTX TITAN starts at $91,406 JPY against $93,389 JPY for the Radeon RX 6400. Because it's both faster and competitively priced, the Radeon RX 6400 wins on performance-per-dollar by about 17%. The GeForce GTX TITAN still sits about $90,407 JPY above its $999 JPY MSRP. The Radeon RX 6400 still sits about $93,230 JPY above its $159 JPY MSRP.
Power & Efficiency
The Radeon RX 6400 sips power at 53W next to the GeForce GTX TITAN's 230W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. 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's 6GB (vs 4GB on the Radeon RX 6400) gives it more room for 4K textures and memory-hungry creative or AI workloads.
Generation & Longevity
The Radeon RX 6400 is roughly 9 years newer than the GeForce GTX TITAN (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 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 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 if you find it at a steep discount.
