GeForce RTX 4070 Ti SUPER vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 4070 Ti SUPER vs Arc B580
The GeForce RTX 4070 Ti SUPER is dramatically faster, around 127% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 4070 Ti SUPER is comfortable at 4K with upscaling and native 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
The Arc B580 currently lists from $260 GBP, $540 GBP less than the GeForce RTX 4070 Ti SUPER at $800 GBP. Despite being slower, the Arc B580 offers the better performance-per-dollar (~35% better value), so budget-focused buyers should weigh it carefully.
Power & Efficiency
On power, the Arc B580 is the gentler choice at 190W versus 285W. The GeForce RTX 4070 Ti SUPER is more efficient per watt because it's faster, but its higher 285W draw means more heat and a bigger PSU.
VRAM & Future-Proofing
VRAM favors the GeForce RTX 4070 Ti SUPER at 16GB versus 12GB on the Arc B580 — that extra 4GB matters most at 4K, with high-res texture packs, and for content-creation/local-AI work.
Features & Ecosystem
Beyond raw numbers, the Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the GeForce RTX 4070 Ti 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 4070 Ti SUPER?
Choose the GeForce RTX 4070 Ti SUPER 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.
