Arc B580 vs RTX 4080: which should you choose?
Arc B580 — Intel desktop graphics card (2024, Battlemage) with 12 GB of GDDR6, averaging 36 fps at 1440p; launched at $249.
RTX 4080 — NVIDIA desktop graphics card (2022, Ada Lovelace) with 16 GB of GDDR6X, averaging 94 fps at 1440p; launched at $1,199.
Arc B580 vs RTX 4080: RTX 4080 is faster for gaming. RTX 4080 averages 94 fps at 1440p versus 36 fps — about 62% faster. Arc B580 draws less power (190W vs 320W).
1080p, 1440p and 4K
At 1440p — the most common enthusiast resolution — the RTX 4080 averages 94 fps against 36. At 4K (20 vs 53 fps) VRAM (12GB vs 16GB) and memory bandwidth matter more.
AI and creator workloads
Beyond gaming, the RTX 4080 is quicker for AI image generation (19.5 vs 2.2 it/s in Stable Diffusion) and local LLM inference (53 vs 26 tokens/s), which increasingly matters for creators and developers.
Power and value
Board power is 190 W versus 320 W, which affects PSU headroom, case cooling and noise. At launch MSRPs of $249 vs $1,199, weigh the frame-rate lead against price and power draw for your target resolution.
The verdict
Both are credible choices in the graphics card comparison space; the specification table above lays out every metric so you can weigh the trade-offs that matter to you. Pick the one whose strengths line up with how you will actually use it.

Methodology
Graphics cards are compared on 3DMark Time Spy scores, average gaming frame rates at 1080p/1440p/4K, FP32 compute throughput, VRAM capacity and type, memory bandwidth, board power (TDP) and launch MSRP — plus AI workload throughput (Stable Diffusion iterations/s and local LLM tokens/s) where measured. Vintage and server GPUs without modern benchmark results are compared on specifications only, clearly labelled. Frame rates are averages across a game suite at high settings; specific titles vary.
