Interesting. I tougth it wass all marketing after all they had 8ghz celeron procesors back in the day. But isnt the limit to liquid cooling the interface between the chip and the fluid? It wold sem very hard to improve on that unles you got bigger chips?

Most gear is still air-cooled but that’s changing pretty quickly
Liquid cools like 3000x more efficiently than air, something like that

I think IBM still has a 5Ghz mainframe chip out there but since multicore era frequency is mostly ~2-3 Ghz
