A new leak about the purported Intel 12th gen Alder Lake-S platform indicates that we might see something on the lines of ARM's big.LITTLE architecture in smartphones being implemented on the desktop. Alder Lake-S is thought to offer up to 16 cores with a TDP ranging from 80 to 150W along with support for PCIe Gen4. The new platform is expected to require an LGA 1700 socket and will likely be made on the 10nm++ process.

Yeah, a 160W part or even 80W part sounds like it doesn't need little cores.
