intel released See the system requirements for Arc Alchemist series desktop graphics accelerators on their website. The manufacturer cites the processors from the older Core 10 series (Comet Lake) as the necessary minimum. The 11th (Rocket Lake) and 12th (Alder Lake) chip series are also given.
According to the description, before using Intel Arc graphics accelerators, the user must ensure that the system supports Resizable BAR technology. Remember that Resizable BAR (ReBAR) gives the CPU access to the graphics card’s entire RAM stack. On AMD systems, this feature is called Smart Access Memory. On the motherboard front, Intel notes that ReBAR support is required to use Arc graphics accelerators. However, the manufacturer reports on this support elsewhere reinforcement necessary “for optimal performance”. Intel also offers a step-by-step guide that explains how to enable Resizable BAR.
The company has not clarified whether desktop Intel Arc graphics cards will work without the Resizable BAR. However, according to reports, it uses the Intel Driver and Support Assistant (IDSA) application, which allows you to keep Intel software up to date “can automatically detect if your computer supports discrete Arc graphics cards”.
Tom’s Hardware downloaded the IDSA application and installed it on his editorial system. It just opens various Intel web pages. It was not possible to use it to check whether your system supports Arc graphics cards. On the open pages of the Intel site, it was noted that IDSA must be started after the Arc card is installed in the computer. And only then can it be verified that Resizable BAR works. In general, no benefit has resulted from this application in the current situation. It is easier to check Resizable BAR activity in motherboard BIOS.
The situation with the 10th generation Intel Core processors, which were declared as the minimum requirement for using Arc graphics, turned out to be no less interesting. Intel’s website states that Resizable BAR support on a platform with Comet Lake chips “may vary” and depends on the specific motherboard model.
It’s also not clear if Intel graphics cards will work with AMD processors. Resizable BAR support is available on Ryzen 3000 and Ryzen 5000 processors, so there shouldn’t be any obstacles here. However, Intel does not name a competitor in the system requirements, so problems can arise.
Recall that Intel has released only one Arc series desktop graphics accelerator so far – Arc A380. The graphics card is only available in China. The company does not specify when the accelerator will appear in other markets.
