So logically, the board must be something with an LGA 1200 socket and a 400 or 500 generation chipset, or an LGA 1700 with a 600 series (or newer) chipset. Officially, they must have a 10th, 11th, or 12th generation Intel Core processor, i.e. Intel Arc graphics cards require PCIe Resizable BAR support (source: Intel)Īccording to the documents, Intel supports Arc graphics operation only in computers that support PCIe Resizable BAR. Activating it usually improves the performance of the graphics card. AMD was the first to come up with it under the Smart Access Memory label, but then the feature was added via BIOS updates by Nvidia and then Intel as well under the PCIe Resizable BAR label. This is a feature that started appearing at the turn of 20 – it’s a designation for technology that extends access to the graphics card memory from the CPU side. Intel states that a PCI Express 3.0 (or newer) ×16 slot is obviously required from the motherboard you’d like to install the Arc A380 card in, although presumably a physical slot that long with only eight active lanes should be sufficient, as the GPU is said to only have a PCIe 4.0 ×8 interface.īut besides that, Intel also states a second requirement: that the board must support the PCIe Resizable BAR feature (or ReBAR). Surprisingly, the Intel Arc A380 graphics documentation states that Intel graphics cards have certain requirements, which is something you don’t usually see in Nvidia and AMD card specifications (except for power supply requirements). However, there are still some oddities: Intel says it requires the board and processor to support PCIe Resizable BAR. It’s only this new product that finally represents a standard graphics card. Intel has tried the waters with the Iris Xe card before, but it bizarrely didn’t work with most PCs except for a few select boards. Intel has finally entered the discrete gaming GPU market, even if it’s just the cheap Arc A380 in China. Arc GPUs do not support all motherboards and CPUs, they have special requirements
