I think everyone's focusing on the core count, but the packaging story is way more interesting here. This thing is 12 separate chiplets on 18A stacked on base dies made on Intel 3, connected to I/O tiles on Intel 7. Three different process nodes in one package, shipping at volume. That's nuts.

And it's clearly an IFS play too. Intel Foundry needs a proof point — you can publish PDKs all day, but nothing sells foundry credibility like eating your own cooking in a 288-core server part at 450W. If Foveros Direct works here, it's the best ad Intel could run for potential foundry customers.

The chiplet sizing is smart for another reason nobody's mentioned: yield. 18A is brand new, yields are probably rough. But 24 cores per die is small enough that even bad yields give you enough good chiplets. Basically AMD's Zen playbook but with a 3D twist.

Also — 64 CXL 2.0 lanes! Several comments here are complaining about DDR5 prices, which is fair. But CXL memory pooling across a rack could change that math completely. I wonder if Intel is betting the real value isn't the cores but being the best CXL hub in the datacenter.

The ARM competition is still the elephant in the room though. "Many efficient cores" is what ARM has always done natively, and 17% IPC uplift on Darkmont doesn't close that gap by itself.
