Intel new Alder lake cpus use more power for faster speed

[smeyer0028]

Intel's new Alderlake consumer desktop CPUs use more power and little-big core design
to seemingly benchmark faster than AMD chips. I do not understand why increasing
power use for significant executiion speed improvement is not good. Here are some
bench marks.

Intel’s Alder Lake big.little CPU design, tested: It’s a barn burner

Intel's power-gulping i9-12900K crushes AMD's Ryzen 9 5950x—even multithreaded.

Well, efficiency matters if you're talking large scale deployment in a datacenter. Peak performance is usually not the most important metric when it comes to operating services on the cloud, there's usually plenty of capacity out there. Single biggest operational cost in a datacenter is cooling and power, not exactly rocket science.

This...exactly this. Reminds me of an article I read regarding why Cloudfare choose AMD over Intel

Cloudflare says Intel is not inside its next-gen servers – Ice Lake melted its energy budget

Alder almost looks like a vanity part... something of little practical use designed to beat AMD in benchmarks.
