Le LGA 4189 est le dernier socket pour la prochaine génération de processeurs Xeon d'Intel

TE Connectivity, the maker of various kinds of connectivity solutions for computer systems, has released its latest iteration of the LGA socket for the next generation of Xeon Scalable CPUs. Being validated by Intel, the LGA 4189-4 and LGA 4189-5 are going to power the next generation of 10 nm Xeon CPUs, based on the Ice Lake architecture, and up to 56-core 2nd generation Xeon Scalable CPUs. While there are two models of the socket, TE Connectivity didn't reveal what the differences are between them. Socket P4 (LGA 4189-4) and P5 (LGA 4189-5) also feature exactly the same pin count, 0.9906 mm hex pitch and 2.7 mm SP height, so we can only speculate that the '4' or '5' in the revision is supposed to indicate details like higher power delivery capability or support for Ice Lake CPUs.

En plus de fournir un nouveau socket pour Ice Lake, ces sockets prennent en charge PCI-Express Gen 4.0 et la mémoire à huit canaux (les configurations de mémoire prises en charge dépendent du fournisseur), ce qui signifie que nous obtenons deux canaux de mémoire de plus que les processeurs Xeon précédents avec un norme PCIe plus rapide et plus récente.
