Leaker reveals Intel Panther Lake iGPU specs and model numbers

Earlier Geekbench listing gave us a glimpse at two of Intel's Panther Lake iGPUs: the Arc B390 and Arc B370. The former would power Core Ultra 9 and Core Ultra 7 SKUs, while the latter would be found on Core Ultra 5 models. X leaker @OneRaichu has now revealed the rest of the lineup, which is as follows:

• Arc B390: 12 EUs, 2.5 GHz boost clock
• Arc B380: 12 EUs, 2.3 GHz boost clock
• Arc B370: 10 EUs, 2.4 GHz boost clock
• Arc B360: 10 EUs, 2.2 GHz boost clock

The 10 EU Arc B380 and Arc B360 will show up in other SKUs, indicating they could be used in non-Panther Lake SKUs. Yet another Geekbench listing confirmed the Arrow Lake desktop refresh is slated to arrive soon with Plus branding, but that will likely stick with the same Arc Xe-LPG iGPU.

However, there has been no word about Intel's high-end HX-branded laptop CPUs so far. As a successor to Lunar Lake, the Panther Lake lineup will not include any new chips, so it stands to reason that they'll be rehashed Arrow Lake laptop chips from last year. The Arc B380 and Arc B360 seem to be plausible candidates for their iGPU.
