Here's a brief overview courtesy of TPU:
The mainstream desktop processors based on "Ice Lake," which are least restrained in power-management, get the most powerful variants of Gen11 under the Iris Plus brand. Iris Plus Graphics 950 is the most powerful implementation, with all 64 EUs enabled, and the highest GPU clock speeds. This variant could feature on Core i7 and Core i9 brands derived from "Ice Lake." Next up, is the Iris Plus Graphics 940, with the same EU count, but likely lower clock speeds, which could feature across the vast lineup of Core i5 SKUs. The Iris Plus 930 comes in two trims based on EU count, of 64 and 48, and could likely be spread across the Core i3 lineup. Lastly, there's the Iris Plus 920 with 32 EUs, which could be found in Pentium Gold SKUs. There are various SKUs branded "UHD Graphics Gen11 LP," with EU counts ranging from 32 to 64.Then there are also Lakefield SoCs with four versions of Gen11 graphics.
