Arc A380 vs Radeon RX 6400: In-Depth Breakdown

Performance: Arc A380 vs Radeon RX 6400

The Arc A380 and Radeon RX 6400 post nearly the same score in our performance index, so neither holds a meaningful raw-speed advantage. Both are best suited to entry-level 1080p gaming.

Price & Value

The Arc A380 currently lists from $1,329 BRL, $199 BRL less than the Radeon RX 6400 at $1,528 BRL. Because it's both faster and competitively priced, the Arc A380 wins on performance-per-dollar by about 15%. The Arc A380 still sits about $1,190 BRL above its $139 BRL MSRP. The Radeon RX 6400 still sits about $1,369 BRL above its $159 BRL MSRP.

Power & Efficiency

At 53W against 75W, the Radeon RX 6400 is both the lower-power and the more efficient card, making it the easier build to cool and power.

VRAM & Future-Proofing

The Arc A380 carries 6GB versus 4GB on the Radeon RX 6400. The extra 2GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.

Features & Ecosystem

Beyond raw numbers, the Arc A380 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 A380 or Radeon RX 6400?

The Arc A380 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.

Frequently Asked Questions

Is the Arc A380 better than the Radeon RX 6400?

They're very close on raw performance. The Arc A380 edges ahead on value, so price and availability should decide it.

Which is better for 4K gaming, the Arc A380 or the Radeon RX 6400?

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

Is the Radeon RX 6400 worth the extra $199 BRL over the Arc A380?

Only if you need the extra performance or features; on pure value the Arc A380 comes out ahead.

Does the Arc A380 have enough VRAM advantage to matter?

Its 6GB (vs 4GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
