Intel plans to update its Xeon Scalable server processor family this year with the new “Ice Lake-SP” microarchitecture. Built on the 10 nm+ silicon fabrication process, “Ice Lake-SP” is a high- thru extreme core-count monolithic silicon that features “Sunny Cove” CPU cores that introduce the first real IPC increases over “Skylake.” A 24-core/48-thread processor likely based on this silicon surfaced on the Geekbench database, where it posted some impressive numbers given its low clock speeds.

The processor comes with an identification string “GenuineIntel Family 6 Model 106 Stepping 4,” with a nominal clock speed of 2.20 GHz, and boost frequency of 2.90 GHz, which points to the possibility of this being an engineering sample. Besides clock speeds and core counts, some basic hardware specs were detected by Geekbench 4. For starters, the processor has an L1D cache size of 48 KB and L1I cache size of 32 KB, which is similar to the client-segment “Ice Lake-U” silicon based Core i7-1065G7, and confirms that this processor uses “Sunny Cove” cores. “Cascade Lake” and “Skylake” cores use 32 KB L1D caches. Also, the dedicated L2 cache per core is 1.25 MB, up from the 1 MB L2 caches on “Cascade Lake.” Client-segment “Ice Lake” chips use 512 KB L2 caches. The shared L3 cache is 36 MB (or 1.5 MB slice per core), which loosely aligns with the cache balance of Intel’s server and HEDT processors. In this bench run, the processor is backed by 256 GB of memory, of an unknown type or configuration. In the three bench runs, the setup scores roughly 4100 points single-core, and roughly 42000 points multi-core.
