GeForce RTX 2080 Ti vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 2080 Ti vs Arc B580
The GeForce RTX 2080 Ti is significantly faster, around 25% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 2080 Ti is comfortable at 1440p, while the Arc B580 is better matched to 1080p.
Power & Efficiency
The Arc B580 draws just 190W versus 250W for the GeForce RTX 2080 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 RTX 2080 Ti's 11GB can fall short.
Generation & Longevity
The Arc B580 is roughly 6 years newer than the GeForce RTX 2080 Ti (Battlemage vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 2080 Ti brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Arc B580 offers Intel XeSS upscaling and AV1 encoding. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce RTX 2080 Ti or Arc B580?
The GeForce RTX 2080 Ti 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.
