Radeon RX 6700 XT vs Radeon RX 6400: In-Depth Breakdown
Performance: Radeon RX 6700 XT vs Radeon RX 6400
The Radeon RX 6700 XT is dramatically faster, around 300% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the Radeon RX 6700 XT is comfortable at 1080p, while the Radeon RX 6400 is better matched to entry-level 1080p. The Radeon RX 6700 XT packs 2,560 stream processors versus 768 on the Radeon RX 6400. The Radeon RX 6700 XT also has more RT cores (40 vs 12), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
The Radeon RX 6700 XT currently lists from $86,631 JPY, $2,841 JPY less than the Radeon RX 6400 at $89,472 JPY. Because it's both faster and competitively priced, the Radeon RX 6700 XT wins on performance-per-dollar by about 313%. The Radeon RX 6700 XT still sits about $86,152 JPY above its $479 JPY MSRP. The Radeon RX 6400 still sits about $89,313 JPY above its $159 JPY MSRP.
Power & Efficiency
At 53W against 230W, the Radeon RX 6400 is both the lower-power and the more efficient card, making it the easier build to cool and power.
VRAM & Future-Proofing
The Radeon RX 6700 XT 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. The Radeon RX 6700 XT's memory is also faster — 384 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 6700 XT?
The Radeon RX 6700 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.
