Frequently Asked Questions
Is the Arc B580 better than the Arc B570?
The Arc B580 is the stronger card overall. It scores 30/100 in synthetic benchmarks and 32/100 in gaming versus 25/100 and 27/100 for the Arc B570. In practical terms, the Arc B580 is a 1080p high card while the Arc B570 targets 1080p high. The Arc B580 also has 12GB of GDDR6 on a 192-bit bus, giving it more headroom for high-res textures and future titles.
Which is the better value, Arc B580 or Arc B570?
The Arc B580 costs $30 more (14% premium) but delivers roughly 20% better performance, making the upgrade worthwhile if your budget allows it. Our value scores reflect this: Arc B580 gets 88/100 and Arc B570 gets 84/100. If you are building on a tighter budget, the Arc B570 at $219 is the smarter buy. If you can stretch to $249 and want the extra performance, the Arc B580 justifies its price for demanding workloads.
Can the Arc B580 or Arc B570 run games at 4K?
Neither card is an ideal 4K GPU. The Arc B580 can manage 4K at medium settings in less demanding titles, but both are really designed for 1080p gaming. If 4K is a priority, consider stepping up to a higher-tier card.
Arc B580 vs Arc B570 for 1440p gaming -- which is better?
At 1440p, the Arc B580 is more comfortable but you may need to dial settings down in newer AAA games. The Arc B570 will struggle at 1440p ultra in demanding titles. For a consistent 1440p experience, the Arc B580 is the safer choice.
What CPU should I pair with the Arc B580 or Arc B570?
To avoid bottlenecking the Arc B580 (gaming score 32/100), pair it with at least a Ryzen 5 7600 or Ryzen 5 9600X. For the Arc B570 (gaming score 27/100), a Ryzen 5 7600 or Ryzen 5 9600X will keep things balanced. Overspending on the CPU relative to the GPU -- or vice versa -- leaves performance on the table. As a rule of thumb, your CPU should cost roughly 40-60% of your GPU budget for a gaming-focused build.
Is the Arc B580 worth it in 2026?
The Arc B580 remains a solid buy in 2026. With 12GB of GDDR6 and Xe2 (Battlemage) architecture, it handles current games at 1080p high settings without issues. Support for XeSS 2 extends its lifespan further by boosting frame rates in supported titles. At $249 MSRP, it offers strong value and should stay relevant for at least another 2-3 years of AAA gaming.
Should I wait for next-gen or buy the Arc B570 now?
If you need a GPU now, the Arc B570 at $219 is a perfectly capable 1080p card. The latest GPUs (NVIDIA RTX 50-series Blackwell, AMD RDNA 4) are now available, so consider comparing against the newest options in your budget. The Arc B570's Xe2 (Battlemage) architecture and 10GB VRAM still have plenty of life left.
How much power does the Arc B580 vs Arc B570 use?
The Arc B580 draws 190W TDP versus 150W for the Arc B570, a difference of 40W. A 650W PSU should handle either card comfortably. The power difference is modest enough that PSU choice should not be a deciding factor between these two. The Arc B570 uses a 1x 8-pin connector while the Arc B580 needs 1x 8-pin.
How many FPS can I expect from the Arc B580 vs Arc B570?
Exact FPS varies by game and settings, but based on our gaming benchmark scores (Arc B580: 32/100, Arc B570: 27/100), the Arc B580 typically delivers 19% more frames than the Arc B570 at the same resolution and settings. In popular titles at 1080p, the Arc B580 with its 13.7 TFLOPS of compute power and 456 GB/s memory bandwidth pushes well above 60 FPS. Enabling XeSS 2 upscaling can boost that by another 30-50% with minimal visual quality loss.
