Radeon R9 390 vs Arc A310: In-Depth Breakdown
Performance: Radeon R9 390 vs Arc A310
The Radeon R9 390 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
The Arc A310 currently lists from $25,439 JPY, $73,407 JPY less than the Radeon R9 390 at $98,846 JPY. Despite being slower, the Arc A310 offers the better performance-per-dollar (~211% better value), so budget-focused buyers should weigh it carefully. The Arc A310 still sits about $25,309 JPY above its $130 JPY MSRP. The Radeon R9 390 still sits about $98,517 JPY above its $329 JPY MSRP.
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 390 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 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 A310 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 A310 or Radeon R9 390?
Choose the Radeon R9 390 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.
