Intel site confirms existence of 1851 socket for Meteor Lake processors – Computer – News

Often the socket identify is the same as the variety of pins. Since Sandy Bridge we have now already moved up from about 1150 pins to 1700 and 1851. The 2011 socket was HEDT with extra reminiscence channels, which require much more connections.

Why the sockets are renewed can also be a thriller to me. In precept, the CPU solely connects to DDR4/5, PCIe, chipset over eg DMI (=PCIe), and presumably I/O buses corresponding to SMbus, SATA, USB, and so forth. These buses don’t change enormously per technology. And provision for extra energy/floor pins (extra energy or sign integrity) could be calculated upfront, I feel.

The biggest in it’s DDR4/DDR5; however in it it’s potential to develop a reminiscence controller that’s appropriate with each variants. Different buses corresponding to PCIe are electrically backwards appropriate, and to utilize the upper communication speeds, the software program can agree with coaching/handshakes which communication customary is used. We additionally know the identical on USB connections, the place a USB-C connector can discuss to units again to USB1.1 (previous keyboard + passive adapters) as much as USB 4 v2.0 (with DP and PCIe tunneling, and so forth.).

Nonetheless, PCBs should be designed to assist the upper communication requirements. There could also be a function distinction; however as mentioned, that should not get out of the best way of being ‘backwards appropriate’.
