We are back with the first of many new GPU launches this year! Things are kicking off with Intel's Arc B570, the smaller sibling of the B580 that hit the market in the middle of December. Alongside its reduced specification, it also sports a reduced price, targeting a $219 MSRP, making this one of the cheapest GPUs that we have reviewed in years. What can it bring to the table at that price point, and how much slower is it than the $249 B580? All that and more is covered in today's review.

Put simply, the Arc B570 is a slightly cut-down version of the B580 that we reviewed last month. It's offering 10% fewer cores, 2GB less VRAM over a narrower memory interface, reduced clock speed, and a more frugal 150W board power rating to match. Accordingly, Intel dropped the price by 12%, targeting a $219 MSRP, with the B580 fetching a $30 premium over this new model.
Pricing and availability remains a significant challenge for the B580 however, and I've not been able to find it in stock for less than £290 over the last week, despite launching at £249. As such, pre-order pricing for the B570 has crept higher than I suspect Intel would like, sitting at £250 here in the UK.
It's also worth confirming that there's no Intel-manufactured Limited Edition – AKA reference – model for the B570 either. Instead we were sent the ASRock Challenger model, with a dual-fan cooler and metal backplate.

First, it's worth recapping the specs for this new GPU. Built on the Xe2 architecture, the B570 uses the same BMG-G21 die as the B580, which is fabricated on TSMC's N5 node, and it has a die size of 272mm2. Comprised of 5 render slices, it is here cut-down to offer 18 cores. Each Xe core offers 16 vector engines, with each vector engine housing eight FP32 ALUs, for a grand total of 2304. Each Xe core is accompanied by a Ray Tracing Unit, while we also find 144 TMUs and 80 ROPs.
The memory subsystem, meanwhile, is new for an Arc GPU. We find 10GB of GDDR6 operating over a 160-bit memory interface, and with memory speed at 19Gbps, total memory bandwidth hits 380 GB/s.
Intel has also been able to crank up the clock speed significantly with Battlemage, but while the B580 has a rated graphics clock of 2670MHz, the B570 is slightly slower, rated at 2500MHz but with a 2750MHz peak clock.
Lastly, total board power is rated at 150W, something we look at closely in this review using our in-depth power testing methodology.
