Intel has already announced that its Arc A-Series will require the Resizable BAR feature to function. Any system not supporting this feature will experience a severe performance loss, and Arc A380 reviews have validated this. Intel is not covering up the fact that its GPUs are not compatible with older systems; the company has been highly vocal about this matter.
This simply suggests that Arc GPUs will need a relatively modern CPU. Anything older than the Ryzen 3000 or Intel 10th Generation Core series is not likely to function appropriately with Arc. However, some older computers do support ReBAR, so there is still a potential that this won’t be a problem. Additionally, Intel Arc requires Windows 10 20H2 or a later version, or Windows 11, so it is incompatible with Windows 7.
Tom Petersen hinted that Intel has no plans to optimize the Arc A-series for systems lacking ReBAR; thus, it is improbable the recommendations will change in the future. This is important to consider when deciding between Arc GPUs and comparable GPUs, which often function without ReBAR without an issue.
The launching of Intel’s Arc A7 GPUs is set for October 12.
