GeForce RTX 4080 SUPER vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 4080 SUPER vs Arc B580
The GeForce RTX 4080 SUPER is dramatically faster, around 146% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 4080 SUPER is comfortable at 4K with upscaling and native 1440p, while the Arc B580 is better matched to 1080p.
Power & Efficiency
The Arc B580 pulls less power (190W vs 320W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 4080 SUPER draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
VRAM & Future-Proofing
With 16GB against 12GB, the GeForce RTX 4080 SUPER has more headroom for 4K textures and memory-hungry creative/AI tasks where the Arc B580's 12GB can fall short.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 4080 SUPER 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 4080 SUPER or Arc B580?
The GeForce RTX 4080 SUPER is the faster card by about 146%. 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.
