Radeon RX 6900 XT vs Arc A380: In-Depth Breakdown
Performance: Radeon RX 6900 XT vs Arc A380
The Radeon RX 6900 XT is dramatically faster, around 567% ahead of the Arc A380. That gap is enough to move it up a tier: the Radeon RX 6900 XT is comfortable at 1440p, while the Arc A380 is better matched to entry-level 1080p.
Power & Efficiency
On power, the Arc A380 is the gentler choice at 75W versus 300W. The Radeon RX 6900 XT is more efficient per watt because it's faster, but its higher 300W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
The Radeon RX 6900 XT carries 16GB versus 6GB on the Arc A380. The extra 10GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The Arc A380 is roughly 2 years newer than the Radeon RX 6900 XT (Alchemist vs RDNA 2), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc A380 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 6900 XT 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 6900 XT?
The Radeon RX 6900 XT is the faster card by about 567%. 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.
