Quote:In a document released a couple of days before the New Year, Intel confirmed that its upcoming Xeon Scalable processors based on the Sapphire Rapids microarchitecture would support on-package HBM memory. A memory subsystem featuring HBM will significantly increase the bandwidth available to the CPU compared to a subsystem that uses conventional types of memory, like DDR4 or DDR5, meaning that future CPUs could resemble today's GPUs with a healthy amount of HBM memory riding on the same package.

So far, Intel has officially confirmed that its Sapphire Rapids processor will feature an eight-channel DDR5 memory controller enhanced with its Data Streaming Accelerator (DSA) technology, which should already provide a significant bandwidth boost over today's DDR4-based memory subsystems. Additionally, the chip will support Intel's next-generation Optane Memory modules.

Intel's Sapphire Rapids processor promises to be a rather massive leap in terms of performance and features over the upcoming Ice Lake-SP chip.
In addition to the all-new Golden Gove microarchitecture that will bring support for Intel’s Advanced Matrix Extensions (AMX) as well as AVX512_BF16 and AVX512_VP2INTERSECT instructions designed for datacenter and supercomputer workloads, the CPU will also support PCIe Gen 5, the CXL 1.1 protocol, and the DSA accelerator. To boost core count, clocks, and yields, Sapphire Rapids is also expected to adopt a chiplet design, though this hasn't been confirmed by Intel.
