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.
Price & Value
Pricing has the Arc A310 at $144 EUR, $220 EUR under the Radeon R9 390X's $364 EUR. Despite being slower, the Arc A310 offers the better performance-per-dollar (~103% better value), so budget-focused buyers should weigh it carefully. The Radeon R9 390X is trading below its $429 EUR MSRP — a genuine deal.
Power & Efficiency
Power draw favors the Arc A310 (30W vs 275W), and it's the more efficient card too, so it's the easy pick if thermals or a smaller PSU matter. 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?
Choose the Radeon R9 390X if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc A310 stretches your money further for only slightly lower performance.
