It's a 165 watt desktop CPU running a single-threaded integer benchmark that doesn't use the other 27 cores, doesn't fully utilize the 6 memory channels or 40 PCIe lanes, etc. Also, you're comparing TDP to average power. Skylake won't come close to the TDP running an integer benchmark (it's the AVX units that really suck power).
Amber Lake Y (a 2-core part with 4.2 GHz turbo) should achieve similar performance on a single-threaded integer benchmark like that, and it's a 5W part. Still, that's incredibly impressive on Apple's part.
