GeForce RTX 2080 Ti vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 2080 Ti vs Arc B580
The GeForce RTX 2080 Ti is noticeably faster, around 14% ahead of the Arc B580. Both cards sit in the same broad class, well suited to 1080p.
Price & Value
Right now the Arc B580 starts at $3,000 BRL against $8,598 BRL for the GeForce RTX 2080 Ti. Despite being slower, the Arc B580 offers the better performance-per-dollar (~152% better value), so budget-focused buyers should weigh it carefully. The Arc B580 still sits about $2,752 BRL above its $248 BRL MSRP. The GeForce RTX 2080 Ti still sits about $7,599 BRL above its $999 BRL MSRP.
Power & Efficiency
The Arc B580 sips power at 190W next to the GeForce RTX 2080 Ti's 250W, and still leads on performance-per-watt — quieter, cooler, and gentler on your PSU. Its more modern Battlemage architecture on a TSMC N5 process is part of why it does more with each watt.
VRAM & Future-Proofing
The Arc B580's 12GB (vs 11GB on the GeForce RTX 2080 Ti) gives it more room for 4K textures and memory-hungry creative or AI workloads.
Generation & Longevity
The Arc B580 is roughly 6 years newer than the GeForce RTX 2080 Ti (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 Ti 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 Ti?
Choose the GeForce RTX 2080 Ti 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.
