Arc B580 vs GeForce RTX 2080 SUPER: In-Depth Breakdown
Performance: Arc B580 vs GeForce RTX 2080 SUPER
The Arc B580 is marginally faster, around 5% ahead of the GeForce RTX 2080 SUPER. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
On price, expect to pay $360 CAD for the Arc B580 versus $495 CAD for the GeForce RTX 2080 SUPER. Because it's both faster and competitively priced, the Arc B580 wins on performance-per-dollar by about 44%. The Arc B580 still sits about $112 CAD above its $248 CAD MSRP. The GeForce RTX 2080 SUPER is trading below its $699 CAD MSRP — a genuine deal.
Power & Efficiency
The Arc B580 draws just 190W versus 250W for the GeForce RTX 2080 SUPER, and it also delivers more performance per watt — so it runs cooler and quieter and needs less PSU headroom. Its more modern Battlemage architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
With 12GB against 8GB, the Arc B580 has more headroom for 4K textures and memory-hungry creative/AI tasks where the GeForce RTX 2080 SUPER's 8GB can fall short.
Generation & Longevity
The Arc B580 is roughly 5 years newer than the GeForce RTX 2080 SUPER (Battlemage vs Turing), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the GeForce RTX 2080 SUPER 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 2080 SUPER?
The Arc B580 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the GeForce RTX 2080 SUPER if you find it at a steep discount.
