GeForce RTX 5080 vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 5080 vs Arc B580
The GeForce RTX 5080 is dramatically faster, around 205% 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.
Price & Value
The Arc B580 currently lists from $341 EUR, $869 EUR less than the GeForce RTX 5080 at $1,210 EUR. Despite being slower, the Arc B580 offers the better performance-per-dollar (~16% better value), so budget-focused buyers should weigh it carefully. The Arc B580 still sits about $93 EUR above its $248 EUR MSRP. The GeForce RTX 5080 still sits about $211 EUR above its $999 EUR MSRP.
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 Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the GeForce RTX 5080 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?
Choose the GeForce RTX 5080 if you want the most performance and can absorb the higher price. If you're optimizing for value, the Arc B580 stretches your money further for only slightly lower performance.
