    Why do CPUs that power hungry exist? I can barely support the thought that my MODERN laptop sucks up to 40W on heavy loads

      That’s an EPYC. It’s a datacenter CPU, and it’s priced accordingly. Nobody uses these at home outside of hardcore homelab enthusiasts with actual rack setups.

      That’s 2.6 Watt per core, about half of what my desktop PC’s CPU uses. And yeah, that’s not for home users.

      Like others have noted, it’s 2-3 Watt’s per core, that’s pretty incredible given how it encompasses all the extra things the CPU does/supports and the inherent cost of it being not a big ol chip.

      Specifically, they support substantially more memory at 12 channels, compared to the typical 2 and 128(+) lanes of PCIe 5 connectivity!

      Because these systems are so dense, data centres can condense N servers into just a couple. And now, you only need 1 set of ancillary components like network cards or fans.

      So, they’re significantly more efficient from a few perspectives.
