Arc B580 vs GeForce GTX 1080 Ti: In-Depth Breakdown
Performance: Arc B580 vs GeForce GTX 1080 Ti
The Arc B580 is significantly faster, around 29% ahead of the GeForce GTX 1080 Ti. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
On price, expect to pay $194 GBP for the GeForce GTX 1080 Ti versus $260 GBP for the Arc B580. Despite being slower, the GeForce GTX 1080 Ti offers the better performance-per-dollar, so budget-focused buyers should weigh it carefully. The GeForce GTX 1080 Ti is trading below its $699 GBP MSRP — a genuine deal.
Power & Efficiency
The Arc B580 draws just 190W versus 250W for the GeForce GTX 1080 Ti, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Battlemage architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 12GB against 11GB, the Arc B580 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce GTX 1080 Ti's 11GB can fall short.
Generation & Longevity
The Arc B580 is roughly 7 years newer than the GeForce GTX 1080 Ti (Battlemage vs Pascal), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the GeForce GTX 1080 Ti 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 B580 or GeForce GTX 1080 Ti?
Choose the Arc B580 if you want the most performance and can absorb the higher price. If you're optimizing for value, the GeForce GTX 1080 Ti stretches your money further for only slightly lower performance.
