>>105825132What happened to socket CPUs, why aren't we seeing a return of them? (Then the PIV Prescott housefire consumed so much energy that made intel consider a whole new mobo form factor just to cool the thing down, but cooler heads prevailed and they made a dual core CPU). But now?
> Small footprint boxen are abound> The pin count of the processors make it harder and harder to design a good socket design.> The vast majority of a CPU's pins are VCC and GND. The new slot should have the VRM next to the cpu as it draws external 12V from a 6/8 pin gpu plug> SMP is a thing now. In the place of a CPU socket, we can have 2 slots.> Cooling tech improved. A lot. We can aircool 3-400W GPUs in a card format. Then aircooling a 100-150W Prescott was a challenge in a socket.This way, the slot can focus on the memory tx/rx and pcie lanes or could have integrated memory modules to the cpu using hbm2 or good types of memory. We would upgrade cpu/ram like we upgrade a gpu now.
If ram was on board, the slot would only need pcie lanes, maybe a few lanes of displayport, and vcc/gnd in order not to get cpu gnd and signal gnd too far from the rest of the mobo. The mobo's responsibility would be to route the pcie lanes, and convert them (ie. to ethernet and sata).
