Intel® Xeon® Processor Scalable Family (Cascade Lake Refresh)

Intel Xeon Platinum InsideIntel Xeon Scalable processors (Cascade Lake Refresh or CLX-R) deliver high levels of compute density, scalability, and storage and memory capacity and feature multiple enhancements for HPC workloads.

The new processors deliver advanced performance with up to 28 cores and significant increases in memory and I/O bandwidth (with six memory channels and 48 PCIe lanes) to handle extremely large compute- and data-intensive workloads.

Cascade Lake CLX-R processors deliver improved Turbo frequencies, up to 4.5 GHz.They also offer support for Intel® OptaneTM DC persistent memory and enhanced DDR4 performance support, which enables more value to be extracted from larger datasets than was previously possible. It also allows for snew data-intensive use cases.

On this page you will meet the next generation of processors. We’re highlighting the key benefits and features, the full SKU list and our systems that support Cascade Lake.
