GeForce RTX 4070 vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 4070 vs Arc B580
The GeForce RTX 4070 is dramatically faster, around 68% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 4070 is comfortable at 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
The Arc B580 currently lists from $1,636 BRL, $10,235 BRL less than the GeForce RTX 4070 at $11,871 BRL. Despite being slower, the Arc B580 offers the better performance-per-dollar (~331% 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 4070 still sits about $11,271 BRL above its $600 BRL MSRP.
Power & Efficiency
On power, the Arc B580 is the gentler choice at 190W versus 200W. The GeForce RTX 4070 is more efficient per watt because it's faster, but its higher 200W draw means more heat and a bigger PSU.
Features & Ecosystem
Beyond raw numbers, the Arc B580 brings Intel XeSS upscaling and AV1 encoding, while the GeForce RTX 4070 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?
Choose the GeForce RTX 4070 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.
