The Telum is a
microprocessor made by
IBM for their
IBM Z
IBM Z is a family name used by IBM for all of its z/Architecture mainframe computers.
In July 2017, with another generation of products, the official family was changed to IBM Z from IBM z Systems; the IBM Z family now includes the newest mod ...
mainframe computers, announced at the
Hot Chips 2021 conference on August 23, 2021. Telum is IBM's first processor that contains on-chip acceleration for AI inferencing while a transaction is taking place.

] The first Telum-based system was the IBM z16, introduced in April 2022.
Description
The chip contains 8 processor cores with a deep
superscalar
A superscalar processor is a CPU that implements a form of parallelism called instruction-level parallelism within a single processor. In contrast to a scalar processor, which can execute at most one single instruction per clock cycle, a supe ...
out-of-order pipeline, running with more than 5 GHz clock frequency, optimized for the demands of heterogenous enterprise class workloads. The completely redesigned cache and chip-interconnection infrastructure provides 32 MB cache per core, and can scale to 32 Telum chips. The dual-chip module design contains 22 billion transistors and 19 miles of wire on 17 metal layers.
