GeForce RTX 3070 Ti vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 3070 Ti vs Arc B580
The GeForce RTX 3070 Ti is significantly faster, around 36% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 3070 Ti is comfortable at 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
Right now the Arc B580 starts at $1,636 BRL against $6,589 BRL for the GeForce RTX 3070 Ti. Despite being slower, the Arc B580 offers the better performance-per-dollar (~195% better value), so budget-focused buyers should weigh it carefully. The Arc B580 still sits about $1,388 BRL above its $248 BRL MSRP. The GeForce RTX 3070 Ti still sits about $5,990 BRL above its $599 BRL MSRP.
Power & Efficiency
The Arc B580 draws just 190W versus 290W for the GeForce RTX 3070 Ti, 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 3070 Ti's 8GB can fall short.
Generation & Longevity
The Arc B580 is roughly 3 years newer than the GeForce RTX 3070 Ti (Battlemage vs Ampere), 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 3070 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 3070 Ti?
Choose the GeForce RTX 3070 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.
