Radeon RX 7900 XT vs Arc A380: In-Depth Breakdown
Performance: Radeon RX 7900 XT vs Arc A380
The Radeon RX 7900 XT is dramatically faster, around 733% ahead of the Arc A380. That gap is enough to move it up a tier: the Radeon RX 7900 XT is comfortable at 4K with upscaling and native 1440p, while the Arc A380 is better matched to entry-level 1080p.
Power & Efficiency
The Arc A380 pulls less power (75W vs 300W), so it's the easier card to cool and the lighter load on your PSU. The faster Radeon RX 7900 XT draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
VRAM & Future-Proofing
With 20GB against 6GB, the Radeon RX 7900 XT has more headroom for 4K textures and memory-hungry creative/AI tasks where the Arc A380's 6GB can fall short.
Features & Ecosystem
Beyond raw numbers, the Arc A380 brings Intel XeSS upscaling and AV1 encoding, while the Radeon RX 7900 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 7900 XT?
The Radeon RX 7900 XT is the faster card by about 733%. 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.
