56 Core Intel Xeon Sapphire Rapids-SP w/ 764W Max Power Limit Spotted: 3.3GHz Boost and 105MB of L3 Cache

Intel’s 4th Gen Xeon Scalable processors are slated for a late 2022 launch. Based on the Golden Cove core architecture and a 10nm ESF (now 7nm) node, these CPUs will combine four tiles (dies) for an overall core count of up to 56. Like most of Intel’s recent offerings, these chips should have been launched by now but have been pushed to the second half of 2022. A new leak from China shows the Sapphire Rapids flagship in action:

The processor in question is an engineering sample running at a base clock of 1.9GHz and a single-core boost of 3.7GHz. The all-core boost is limited to 3.3GHz. The 4th Gen Xeon-SP was tested on an LGA 4677 socket. It has a base clock of 350W and a boost of 420W. In comparison, AMD’s 3rd Gen Epyc Milan processors have a boost TDP of just 280W despite leveraging a total of 64 cores. The crazy part is that this particular sample has a max power draw of 764W allowed by the firmware which is absolutely bonkers. This is likely the power limit with AVX-512 enabled.

The CPU comes with 105MB of L3 cache (a step up from Ice Lake and Cooper Lake) but is still a far cry from the 256MB on AMD’s Epyc lineup. The Sapphire Rapids family is going to go up against Team Red’s 4th Gen Epyc Genoa family. The Zen 4-based processors will come with as many as 96 cores and a beefed-up IPC to boot.
