Microsoft is first to get HBM-juiced AMD CPUs (nextplatform.com)
Intel was the first of the major CPU makers to add HBM stacked DRAM memory to a CPU package, with the “Sapphire Rapids” Max Series Xeon SP processors. But with the “Granite Rapids” Xeon 6, Intel abandoned the use of HBM memory in favor of what it would hope would be more main stream MCR DDR5 main memory, which has multiplexed ranks to boost bandwidth by nearly 2X over regular DDR5 memory.
