Radeon R9 390X vs Arc A310: In-Depth Breakdown
Performance: Radeon R9 390X vs Arc A310
The Radeon R9 390X is significantly faster, around 25% ahead of the Arc A310. Both cards sit in the same broad class, well suited to entry-level 1080p.
Power & Efficiency
At 30W against 275W, the Arc A310 is both the lower-power and the more efficient card, making it the easier build to cool and power. Its more modern Alchemist architecture on a TSMC N6 process is part of why it does more with each watt.
VRAM & Future-Proofing
The Radeon R9 390X carries 8GB versus 4GB on the Arc A310. The extra 4GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Generation & Longevity
The Arc A310 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 A310 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 A310 or Radeon R9 390X?
The Radeon R9 390X is the faster card by about 25%. 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.
