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.

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?

The Radeon R9 390 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.

Frequently Asked Questions

Is the Radeon R9 390 better than the Arc A310?

The Radeon R9 390 is significantly faster, roughly 25% ahead. If your budget allows, it's the stronger pick.

Which is better for 4K gaming, the Arc A310 or the Radeon R9 390?

Neither is a dedicated 4K card; both are best at entry-level 1080p. For 4K you'd want a faster GPU, or lean on upscaling.

Does the Radeon R9 390 have enough VRAM advantage to matter?

Its 8GB (vs 4GB) gives real headroom for 4K, heavy texture mods, and creative/AI work. At 1080p the gap matters less.
