Arc A380 vs Radeon R9 390: In-Depth Breakdown
Performance: Arc A380 vs Radeon R9 390
The Arc A380 is significantly faster, around 20% ahead of the Radeon R9 390. Both cards sit in the same broad class, well suited to entry-level 1080p.
Price & Value
Right now the Arc A380 starts at $861 AED against $2,133 AED for the Radeon R9 390. Because it's both faster and competitively priced, the Arc A380 wins on performance-per-dollar by about 197%. The Arc A380 still sits about $722 AED above its $139 AED MSRP. The Radeon R9 390 still sits about $1,804 AED above its $329 AED MSRP.
Power & Efficiency
The Arc A380 draws just 75W versus 275W for the Radeon R9 390, 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 390 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 390 (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 390 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 390?
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 R9 390 if you find it at a steep discount.
