Radeon RX 6950 XT vs Radeon RX 6400: In-Depth Breakdown
Performance: Radeon RX 6950 XT vs Radeon RX 6400
The Radeon RX 6950 XT is dramatically faster, around 600% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the Radeon RX 6950 XT is comfortable at 4K with upscaling and native 1440p, while the Radeon RX 6400 is better matched to entry-level 1080p. The Radeon RX 6950 XT packs 5,120 stream processors versus 768 on the Radeon RX 6400. The Radeon RX 6950 XT also has more RT cores (80 vs 12), strengthening its ray-tracing and AI-upscaling performance.
Price & Value
Right now the Radeon RX 6400 starts at $183 EUR against $700 EUR for the Radeon RX 6950 XT. Because it's both faster and competitively priced, the Radeon RX 6950 XT wins on performance-per-dollar by about 83%. The Radeon RX 6950 XT is trading below its $1,099 EUR MSRP — a genuine deal.
Power & Efficiency
The Radeon RX 6400 pulls less power (53W vs 335W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 6950 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
VRAM & Future-Proofing
With 16GB against 4GB, the Radeon RX 6950 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 6950 XT's memory is also faster — 576 GB/s versus 128 GB/s (256-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 6950 XT?
The Radeon RX 6950 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.
