GeForce RTX 3080 12GB vs Arc A580: In-Depth Breakdown
Performance: GeForce RTX 3080 12GB vs Arc A580
The GeForce RTX 3080 12GB is dramatically faster, around 131% ahead of the Arc A580. That gap is enough to move it up a tier: the GeForce RTX 3080 12GB is comfortable at 1440p, while the Arc A580 is better matched to 1080p.
Price & Value
Pricing has the Arc A580 at $228 GBP, $843 GBP under the GeForce RTX 3080 12GB's $1,070 GBP. Despite being slower, the Arc A580 offers the better performance-per-dollar (~103% better value), so budget-focused buyers should weigh it carefully. The GeForce RTX 3080 12GB still sits about $271 GBP above its $799 GBP MSRP.
Power & Efficiency
At 175W vs 350W, the Arc A580 is the gentler load on your system. The GeForce RTX 3080 12GB's extra power draw buys more performance per watt, not just more heat — worth it if your PSU has the headroom.
VRAM & Future-Proofing
The GeForce RTX 3080 12GB carries 12GB versus 8GB on the Arc A580. The extra 4GB helps at 4K, with high-resolution texture packs, and for content-creation or local-AI workloads that exhaust smaller buffers.
Features & Ecosystem
Beyond raw numbers, the Arc A580 brings Intel XeSS upscaling and AV1 encoding, while the GeForce RTX 3080 12GB offers NVIDIA DLSS upscaling/frame generation and stronger ray tracing. 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 A580 or GeForce RTX 3080 12GB?
Choose the GeForce RTX 3080 12GB if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc A580 stretches your money further for only slightly lower performance.
