Digging a little deeper into Intel's Xe3 architecture shows exactly why Panther Lake's iGPU is good: It's basically an Arc A770 graphics card jammed into a mobile chip

After the early promises of how good Intel's Xe3 GPU architecture could be, thanks to Intel's breakdown of the changes implemented to everything, we finally got to test one properly last month in the form of a Panther Lake laptop. And you know what? It is good. Very good, in fact.

On paper, that should be a given. Intel's Arc B390 only sports 1536 shaders, but with 16 MB of L2 cache and a boost clock of 2.5 GHz, that's way more potent than most integrated GPUs.

Leaving aside AMD's Ryzen AI Max chips (aka Strix Halo)...
