“Intel reference platform for new Xeon CPUs supports TDPs up to 500W”

Details have emerged about Intel’s Avenue City reference platform. The platform would be intended for the upcoming Granite Rapids and Sierra Forest data center CPUs. The platform should offer twelve DDR5 channels and support TDPs up to 500W.

Granite Rapids and Sierra Forest are coming according to a slide from hardware leaker YuuKi_AnS out on socket LGA-7529. According to the leaker, that platform will receive support for processors with TDPs of up to 500W. As an illustration, the recently released Sapphire Rapids CPUs come with TDPs up to 350W.

Furthermore, the platform must offer twelve DDR5 memory channels. The maximum memory speeds are 6400 megatransfers per second when a CPU socket is used. The slide also mentions support for PCIe 5.0, though the leaked slide doesn’t mention a concrete number of lanes. The reference platform includes a motherboard with a twenty-layer pcb. The board is approximately 42cm wide and 50cm long. The motherboard also has 24 DDR5 slots and two sockets.

Intel previously shared details about its Granite Rapids and Sierra Forest CPUs. The former will be the successor to Emerald Rapids, a series of server processors that is planned for this year. Sierra Forest will be the first line of server CPUs to make full use of E-cores. Intel has been using such cores in its desktop processors since 2021’s Alder Lake, albeit paired with more powerful P-cores. E-cores are more energy efficient, but slower than P-cores. The efficient cores also do not offer hyperthreading. The CPUs are made on the Intel 3 process.
