GeForce RTX 3070 vs Arc B580: In-Depth Breakdown
Performance: GeForce RTX 3070 vs Arc B580
The GeForce RTX 3070 is noticeably faster, around 17% ahead of the Arc B580. That gap is enough to move it up a tier: the GeForce RTX 3070 is comfortable at 1440p, while the Arc B580 is better matched to 1080p.
Price & Value
Right now the Arc B580 starts at $289 GBP against $297 GBP for the GeForce RTX 3070. Because it's both faster and competitively priced, the GeForce RTX 3070 wins on performance-per-dollar by about 14%. The GeForce RTX 3070 is trading below its $499 GBP MSRP — a genuine deal.
Power & Efficiency
The Arc B580 pulls less power (190W vs 220W), so it's the easier card to cool and the lighter load on your PSU. The faster GeForce RTX 3070 draws more overall but extracts more performance from each watt — plan for a sturdier power supply if you pick it.
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's 8GB can fall short.
Generation & Longevity
The Arc B580 is roughly 4 years newer than the GeForce RTX 3070 (Battlemage vs Ampere), so it generally benefits from a more modern architecture and longer driver-support runway.
Features & Ecosystem
Beyond raw numbers, the GeForce RTX 3070 brings NVIDIA DLSS upscaling/frame generation and stronger ray tracing, while the Arc B580 offers Intel XeSS upscaling and AV1 encoding. If you lean on upscaling or ray tracing, that ecosystem difference can matter as much as the frame-rate gap.
Which should you buy: GeForce RTX 3070 or Arc B580?
The GeForce RTX 3070 is the all-round winner here — it's faster and the better value, so buy it if it fits your budget. Only consider the Arc B580 if you find it at a steep discount.
