Last week IBM announced their next generation mainframe CPU Telum. Manufactured by Samsung's 7nm node, each Telum processor has 8 cores with each core running at a base 5GHz. Two processors are combined in a package similar to AMD's chiplet design. A drawer in each mainframe can hold 4 packages (sockets), and the mainframe can hold 4 drawers for combined 256 cores. Different from previous generations, there is no dedicated L3 or L4 cache. Instead each core has a 32MB L2 cache that can pool to become a 256MB L3 "virtual" cache on the same processor or 2GB L4 "virtual" cache on the same drawer. Also included to help with AI is a on-die but not on-core inference accelerator running at 6TFLOPS using Intel's AVX-512 to communicate with the cores. The predecessor IBM z15 chip was designed to enable industry-leading seven nines availability for IBM Z and LinuxONE systems. Telum is engineered to further improve upon availability with key innovations including a redesigned 8-channel memory interface capable of tolerating complete channel or DIMM failures and designed to transparently recover data without impact to response time.
