Resizable-BAR a Must for Arc "Alchemist," Stick with Other Vendors if you Lack it: Intel

gasolina · Sep 7, 2022

I think intel will release these gpu in november and drop support by the end of december 2023 . i would just bash all intel gpu since buying them meaning encouraging corps give us overpriced + unfinished products . If the arc 770 is 300$ and support up to 3 years then it's decent deal but intel is intel their product are shortlived

Intel mentioned Resizable BAR as a requirement for optimal performance several months ago, even before the first ARC GPUs were released and testing promptly confirmed the performance degradation without ReBAR. The ironic thing is that it mostly hits people on older (before the series 400 mobos) Intel platforms, maybe Intel thinks it will prompt them to upgrade?

Your post basically explains why I don't believe it was a design feature. Tom & Ryan need to eplain how all the game developers will update their memory management for Re-BAR on old titles.

The mb in question is an Asus ROG Crosshair VII Hero wifi. He knew going in that it didn't support rebar but spoke to an Asus engineer that said there was a possibility. So he gave it a try but failed.

And yes he's wise enough to know how to update the bios to the latest version...

He tested the a380 in his i5 rig and still couldn't get it to work as the primary gpu. Returning the gpu as defective. Rebars reputation saved!
