Arc A750 vs Radeon RX 6400: In-Depth Breakdown

Performance: Arc A750 vs Radeon RX 6400

The Arc A750 is dramatically faster, around 200% ahead of the Radeon RX 6400. That gap is enough to move it up a tier: the Arc A750 is comfortable at 1080p, while the Radeon RX 6400 is better matched to entry-level 1080p.

Price & Value

Right now the Radeon RX 6400 starts at $10 EUR against $58 EUR for the Arc A750. Despite being slower, the Radeon RX 6400 offers the better performance-per-dollar (~87% better value), so budget-focused buyers should weigh it carefully. The Radeon RX 6400 is trading below its $159 EUR MSRP — a genuine deal. The Arc A750 is trading below its $289 EUR MSRP — a genuine deal.

Power & Efficiency

The Radeon RX 6400 draws just 53W versus 225W for the Arc A750, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom.

VRAM & Future-Proofing

With 8GB against 4GB, the Arc A750 has more headroom for 4K textures and memory-hungry creative/AI tasks where the Radeon RX 6400's 4GB can fall short.

Features & Ecosystem

Beyond raw numbers, the Arc A750 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 6400 offers AMD FSR upscaling and strong rasterization value. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.

Which should you buy: Arc A750 or Radeon RX 6400?

Choose the Arc A750 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.

Frequently Asked Questions

Is the Arc A750 better than the Radeon RX 6400?

The Arc A750 is dramatically faster, roughly 200% ahead. The Radeon RX 6400 is still worth it if value matters more than top-end frames.

Which is better for 4K gaming, the Arc A750 or the Radeon RX 6400?

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

Is the Arc A750 worth the extra $47 EUR over the Radeon RX 6400?

Only if you need the extra performance or features; on pure value the Radeon RX 6400 comes out ahead.

Does the Arc A750 have enough VRAM advantage to matter?

Its 8GB (vs 4GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
