The first pictures of Intel’s Alder Lake-S desktop CPUs have surfaced (shared by VC). Below, you can see the 10th Gen Comet Lake-S and Alder Lake-S processors in a side-by-side comparison. Right off the bat, one thing is clear. The latter is a notably larger package due to the use of two different core architectures on the same die which will likely be one chiplet each, connected by Intel’s EMIB interconnect.
The notch placement is also completely different. While Comet Lake has two on the sides, towards the bottom, Alder Lake has two on the top-side and two on the bottom-side. The capacitor configuration also has a different layout on Alder Lake-S, with two large groups and two smaller ones. These likely feed the different core clusters, the former for the performance and the latter for low-power cores:
