Radeon RX 7700 XT vs Radeon RX 6400: In-Depth Breakdown
Performance: Radeon RX 7700 XT vs Radeon RX 6400
The Radeon RX 7700 XT is dramatically faster, around 433% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the Radeon RX 7700 XT is comfortable at 1440p, while the Radeon RX 6400 is better matched to entry-level 1080p. The Radeon RX 7700 XT packs 3,456 stream processors versus 768 on the Radeon RX 6400.
Price & Value
Right now the Radeon RX 7700 XT starts at $74,454 JPY against $89,472 JPY for the Radeon RX 6400. Because it's both faster and competitively priced, the Radeon RX 7700 XT wins on performance-per-dollar by about 541%. The Radeon RX 7700 XT still sits about $74,005 JPY above its $449 JPY MSRP. The Radeon RX 6400 still sits about $89,313 JPY above its $159 JPY MSRP.
Power & Efficiency
The Radeon RX 6400 pulls less power (53W vs 245W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 7700 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it. Its more modern RDNA 3 architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 12GB against 4GB, the Radeon RX 7700 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 7700 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 7700 XT?
The Radeon RX 7700 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.
