GeForce RTX 5080 Laptop vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 5080 Laptop vs Arc B580
The GeForce RTX 5080 Laptop is dramatically faster, around 91% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 5080 Laptop is comfortable at 4K with upscaling and native 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
Right now the Arc B580 starts at $289 GBP against $2,199 GBP for the GeForce RTX 5080 Laptop.
Power & Efficiency
The GeForce RTX 5080 Laptop draws just 150W versus 190W for the Arc B580, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Blackwell architecture on a TSMC 4NP process is part of why it does more with each watt.
Features & Ecosystem
Beyond raw numbers, the Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the GeForce RTX 5080 Laptop 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 RTX 5080 Laptop?
The GeForce RTX 5080 Laptop is the faster card by about 91%. 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.
