Cascade Lake R (Cascade Lake Scalable Performance Refresh) is code name for Intel's series of server multiprocessors based on the Cascade Lake microarchitecture as part of the Purley platform serving as mid-cycle refresh to Cascade Lake SP. Cascade Lake R only targets mainstream entry and mid-range servers and therefore only support up to 2-way multiprocessing. As with Cascade Lake SP, these chips also support up to 28 cores, incorporate AVX512 x86 extension for neural network / deep learning workloads, and introduces persistent memory support. Cascade Lake R-based chips are manufactured on an enhanced 14 nm process and utilize the Lewisburg chipset.

Cascade Lake R-based models are branded as the 2nd-generation Xeon Bronze, Xeon Silver, and Xeon Gold processor families.
