GeForce RTX 5080 vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 5080 vs Arc B580
The GeForce RTX 5080 is dramatically faster, around 183% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 5080 is comfortable at 4K and high-refresh 1440p, while the Arc B580 is better matched to 1080p.
Power & Efficiency
On power, the Arc B580 is the gentler choice at 190W versus 360W. The GeForce RTX 5080 is more efficient per watt because it's faster, but its higher 360W draw means more heat and a bigger PSU. Its more modern Blackwell architecture on a TSMC 4N process is part of why it does more with each watt.
VRAM & Future-Proofing
The GeForce RTX 5080 carries 16GB versus 12GB on the Arc B580. 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 GeForce RTX 5080 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 5080 or Arc B580?
The GeForce RTX 5080 is the faster card by about 183%. 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.
