In support of Genoa's 96 cores, AMD introduced the SP5 socket with 2022 more contact pins than the SP3 socket to provide greater power delivery and signal integrity. SP5 can provide a peak power of up to 700 W.The SP5 socket supports Epyc processors codenamed Bergamo, which have up to 128 small Zen 4c cores and were launched on June 13, 2023.
