Radeon RX 7600 vs Radeon RX 6400: In-Depth Breakdown
Performance: Radeon RX 7600 vs Radeon RX 6400
The Radeon RX 7600 is dramatically faster, around 233% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the Radeon RX 7600 is comfortable at 1080p, while the Radeon RX 6400 is better matched to entry-level 1080p. The Radeon RX 7600 packs 2,048 stream processors versus 768 on the Radeon RX 6400.
Price & Value
Right now the Radeon RX 6400 starts at $10 EUR against $279 EUR for the Radeon RX 7600. Despite being slower, the Radeon RX 6400 offers the better performance-per-dollar (~713% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6400 is trading below its $159 EUR MSRP — a genuine deal.
Power & Efficiency
The Radeon RX 6400 pulls less power (53W vs 165W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 7600 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 N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 8GB against 4GB, the Radeon RX 7600 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 7600's memory is also faster — 288 GB/s versus 128 GB/s (128-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 7600?
Choose the Radeon RX 7600 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Radeon RX 6400 stretches your money further for only slightly lower performance.
