Details regarding Intel's 4th Gen Xeon family codenamed Sapphire Rapids-SP have leaked out a day after the launch of the 3rd Gen Xeon family. The Sapphire Rapids-SP family will be replacing the Ice Lake-SP family and will go all on board with the 10nm Enhanced SuperFin process node that will be making its formal debut later this year in the Alder Lake consumer family.

In an SKU chart posted by Momomo_US, three Intel Sapphire Rapids-SP Xeon CPUs are disclosed. All three SKUs are engineering samples and come with various core configurations. From what we know so far, Intel's Sapphire Rapids-SP lineup is expected to utilize the Golden Cove architecture & will be based on the 10nm Enhanced SuperFin process node.
