Intel site confirms socket 1851 for Meteor Lake processors – Computing – News

Usually the socket name is equal to the pin number. So since Sandy Bridge we already went from about 1150 pins to 1700 and 1851. The 2011 socket was HEDT with more memory channels, requiring much more connections.

Why the outlets are being refurbished is also a mystery to me. In principle, the CPU only connects to DDR4/5, PCIe, chipsets via e.g. DMI (=PCIe) and possibly I/O buses such as SMbus, SATA, USB, etc. These buses don’t change hugely per generation. And the provision of more power/ground pins (more power or signal integrity) can be calculated in advance I think.

The largest is DDR4/DDR5; but in it it is possible to develop a memory controller compatible with both variants. Other buses such as PCIe are electrically backward compatible, and to utilize the higher communication speeds, the software can agree with training/handshake which communication standard is being used. We also know the same about USB connections, where a USB-C connector can communicate with devices up to USB 1.1 (old keyboard + passive adapters) up to USB 4 v2.0 (tunneled DP and PCIe, etc).

However, printed circuit boards must be designed to support the highest communication standards. There may be a difference in functionality; but as mentioned, that shouldn’t get out of the way to be “backwards compatible”.
