Rumor: Intel Emerald Rapids Xeon CPUs for servers will get up to 64 cores

A leaker has published the possible specifications of Intel Emerald Rapids. These server CPUs would get 64 cores and DDR5-5600 support. Emerald Rapids is due out next year and will be the successor to Sapphire Rapids, which has still not appeared due to delay.

Emerald Rapids according to well-known processor leaker YuuKi_AnS multiple improvements over Sapphire Rapids. For example, Intel would introduce models with 64 P cores, while Intel ships its Sapphire Rapids CPUs with up to 56 cores. In addition, Emerald Rapids will get better memory support, according to the leaker, with eight memory channels and official support for DDR5-5600 when one dimm per channel is used. With two dimms per channel, the maximum speed is 4800 mega transfers per second. The processors get TDPs from 125 to 350W.

The processors are again produced on the Intel 7 process, which was previously known as 10nm Enhanced Superfin. The chips will use the same socket LGA-4677 that Sapphire Rapids also uses. It is unknown what microarchitecture Emerald Rapids is based on. For example, Sapphire Rapids features Golden Cove cores, which are also used in the Alder Lake consumer platform. Presumably Emerald Rapids will be based on Raptor Lake.

Intel Emerald Rapids processors would further support PCIe 5.0 and provide up to eighty 80 PCIe lanes, with bifurcation support on x16, x8, x4 and x2 through PCIe 4.0. The chipset should provide twenty additional PCIe 3.0 lanes. Emerald Rapids is planned for 2023. The manufacturer says it is convinced that it will meet this deadline. However, Sapphire Rapids, the predecessor of Emerald Rapids, had to deal with multiple postponements. Those CPUs were initially planned for last year, but have now been pushed to the beginning of 2023.
