The Radeon RX 6750 XT is dramatically faster, around 333% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the Radeon RX 6750 XT is comfortable at 1440p, while the Radeon RX 6400 is better matched to entry-level 1080p. The Radeon RX 6750 XT packs 2,560 stream processors versus 768 on the Radeon RX 6400. The Radeon RX 6750 XT also has more RT cores (40 vs 12), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
Right now the Radeon RX 6400 starts at $89,472 JPY against $144,403 JPY for the Radeon RX 6750 XT. Because it's both faster and competitively priced, the Radeon RX 6750 XT wins on performance-per-dollar by about 168%. The Radeon RX 6400 still sits about $89,313 JPY above its $159 JPY MSRP. The Radeon RX 6750 XT still sits about $143,854 JPY above its $549 JPY MSRP.
Power & Efficiency
The Radeon RX 6400 draws just 53W versus 250W for the Radeon RX 6750 XT, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.
VRAM & Future-Proofing
With 12GB against 4GB, the Radeon RX 6750 XT has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6400's 4GB can fall short. The Radeon RX 6750 XT's memory is also faster — 432 GB/s versus 128 GB/s (192-bit vs 64-bit bus) — which helps feed the GPU at 4K and with heavy textures.
Which should you buy: Radeon RX 6400 or Radeon RX 6750 XT?
The Radeon RX 6750 XT 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.
