Running Four Intel Graphics Cards Under Linux On Ubuntu 26.04
With each Intel Arc Pro B70 BMG-G31 graphics card sporting 32GB of GDDR6 video memory, the combined 128GB of vRAM between four B70 graphics cards can allow for some much larger large language models (LLMs). For the purposes of the testing today was getting an idea for the scaling though of the Arc Pro B70 graphics cards from one to four across different workloads, so taking into account workloads that could run on a single Arc Pro B70 and also supported multi-card/adapter scaling.
With the Hashcat OpenCL-based password recovery program, multiple OpenCL graphics cards are supported. With this Arc Pro B70 testing Hashcat was scaling well up to three Arc Pro B70s.
After three Arc Pro B70 graphics cards, Hashcat was no longer scaling its performance across any of the algorithms tested.
With the latest Blender 5.1 3D modeling software and using the Intel oneAPI back-end, there was good performance scaling from one to two Arc Pro B70 graphics cards. With three cards the performance benefit was still there but not as significant as from one to two graphics cards. Similar to Hashcat, with four Arc Pro B70 graphics cards there wasn't any benefit over the three card configuration tested.
