Radeon RX 6700M vs Radeon RX 6400: In-Depth Breakdown

Performance: Radeon RX 6700M vs Radeon RX 6400

The Radeon RX 6700M is dramatically faster, around 283% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the Radeon RX 6700M is comfortable at 1080p, while the Radeon RX 6400 is better matched to entry-level 1080p. The Radeon RX 6700M packs 2,304 stream processors versus 768 on the Radeon RX 6400. The Radeon RX 6700M also has more RT cores (36 vs 12), strengthening its ray-tracing and AI-upscaling performance.

Power & Efficiency

On power, the Radeon RX 6400 is the gentler choice at 53W versus 135W. The Radeon RX 6700M is more efficient per watt because it's faster, but its higher 135W draw means more heat and a bigger PSU.

VRAM & Future-Proofing

The Radeon RX 6700M carries 10GB versus 4GB on the Radeon RX 6400. The extra 6GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers. The Radeon RX 6700M's memory is also faster — 320 GB/s versus 128 GB/s (160-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 6700M?

The Radeon RX 6700M is the faster card by about 283%. With live pricing limited for this pair, base your decision on the spec differences above — particularly VRAM and power draw — and check current stock before buying.

Frequently Asked Questions

Is the Radeon RX 6700M better than the Radeon RX 6400?

The Radeon RX 6700M is dramatically faster, roughly 283% ahead. If your budget allows, it's the stronger pick.

Which is better for 4K gaming, the Radeon RX 6400 or the Radeon RX 6700M?

Neither is a dedicated 4K card; both are best at 1080p. For 4K you'd want a faster GPU, or lean on upscaling.

Does the Radeon RX 6700M have enough VRAM advantage to matter?

Its 10GB (vs 4GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.

Which is better for ray tracing, the Radeon RX 6700M or the Radeon RX 6400?

Both handle ray tracing, but the Radeon RX 6700M has more RT cores, giving it better ray-tracing and AI-upscaling performance than the Radeon RX 6400.
