> QX9300 Core 2 Quad (socketed CPU!!

Yes, socketed CPU on a laptop! The HP equivalent to the M4400, Elitebook 8530w, even had a slotted GPU (MXM slot), which you could upgrade, wow! I loved doing that kind of upgrade with older workstations.

Sadly, Haswell is the last chip that was socketed on laptops. Anything newer and you get a pre-soldered chip that you can't upgrade.

They can be overclocked substantially, partly thanks to FIVR (VRMs on-die, Haswell exclusive, very hot - literally), often outperforming Skylake and even newer chips lol

Only solution nowadays if you want a laptop is to get one of the rare ones using a desktop CPU. They're surprisingly not as huge as you'd imagine, about the same as the article's Elitebook. Still, a pain in the ass.
