A 4x perf/W improvement on multithreaded workloads (well, a multithreaded workload at least) is pretty impressive. But, its important to note that that is comparing to Rocket Lake, a stopgap processor family manufactured on Intel's old 14nm process. Alder Lake is "Intel 7" (or third generation 10nm before the rename - supposedly similar performance to TSMC N7).

Personally, I'm more interested in their laptop CPUs where efficiency is more important. But, there is presumably less to be gained since Intel's current Tiger Lake platform is already on their second generation 10nm process. Intel said today that Alder Lake laptop CPUs are shipping next month, but they still havent been formally announced.
