Intel's new 12th gen Alder Lake platform brings with several notable changes on the architecture side. Alder Lake processors use a heterogeneous ISA with a shared L3 cache and an intelligent Thread Director that helps the OS in proper scheduling of threads. The CPU brings support for DDR5-4800 RAM and PCIe Gen5, but the Z690 chipset supports only PCIe Gen4 and Gen3.

This is not a heterogeneous ISA. This is heterogeneous microarchitecture. Please make the correction. This heading is technically highly wrong. ISA means instruction set architecture. Microarchitecture is its implementation. Which are the heterogeneous cores here. One ISA can have many implementations.
"There is also support for up to 4x USB 3.2 Gen2x2, 10x USB 3.2 Gen2, 10x USB 3.2 Gen1, and 14 USB 2.0 ports, so connectivity shouldn't be an issue at all. Finally, there are eight lanes of SATA 6 Gb/s ports for storage expansion. "
Unfortunately, they wont implant it in the motherboards...
So dont hope to see a motherboard with 4x USB 3.2 Gen2x2
Title of this article is misleading, Alderlake is not an Heterogeneous ISA but it's a Heterogeneous Architecture. ISA is still homogeneous.
