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
Pricing has the Arc A380 at $130 USD, $48 USD under the Radeon RX 6400's $178 USD. Because it's both faster and competitively priced, the Arc A380 wins on performance-per-dollar by about 37%.
Power & Efficiency
Power draw favors the Radeon RX 6400 (53W vs 75W), and it's the more efficient card too, so it's the easy pick if thermals or a smaller PSU matter.
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.
