A new Geekbench listing has revealed more prospective performance for another of Intel's forthcoming Panther Lake iGPUs. For context, the company's Arc B390 iGPU was spotted last month on Geekbench OpenCL.
As we discussed at the time, the Arc B390 scored over a third more than the Arc 140T while managing a circa 92% improvement over the Arc 140V that underpins ultrabooks like the XPS 13 9350 (curr. $1,399 on Amazon). By contrast, the iGPU inside the Core Ultra 7 366H does not fare as well.
Unfortunately, Geekbench does not identify how many Arc Xe3 cores this iGPU possesses. Nonetheless, its score of 22,813 in Geekbench 6.5.0 Vulkan puts it on par with the Radeon 840M and its 4 Compute Units (CUs). Potentially, this could be the same iGPU found in the Core Ultra 5 336H and Core Ultra 5 338H rather than 10-core equivalents like the Arc B360 or Arc B370.
As a result, the Core Ultra 7 366H comes up around 25% short of Arc 140V-powered processors in the same benchmark and is 34% down on Arc 140T counterparts. Likewise, the score shown below represents a 50% drop on the Radeon 890M. Currently, the Core Ultra 7 336H has only appeared in the Dell Pro Precision 7 16, a successor to the Dell Pro Max 16 Plus that replaced the Precision 7680 earlier this year.
