Arc A380 vs Radeon R9 390X: In-Depth Breakdown
Performance: Arc A380 vs Radeon R9 390X
The Arc A380 is significantly faster, around 20% ahead of the Radeon R9 390X. Both cards sit in the same broad class, well suited to entry-level 1080p.
Power & Efficiency
The Arc A380 draws just 75W versus 275W for the Radeon R9 390X, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Alchemist architecture on a TSMC N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 8GB against 6GB, the Radeon R9 390X has more headroom for 4K textures and memory-hungry creative/AI tasks where the Arc A380's 6GB can fall short.
Generation & Longevity
The Arc A380 is roughly 7 years newer than the Radeon R9 390X (Alchemist vs GCN 2.0), 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 R9 390X 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 R9 390X?
The Arc A380 is the faster card by about 20%. 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.
