Description
The chip contains 8 processor cores with a deepsuperscalar
A superscalar processor (or multiple-issue 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 in ...

A pipeline is a system of Pipe (fluid conveyance), pipes for long-distance transportation of a liquid or gas, typically to a market area for consumption. The latest data from 2014 gives a total of slightly less than of pipeline in 120 countries ...
, running with more than 5 GHz clock frequency which is optimized for the demands of heterogenous enterprise-class workloads (e.g: finance, security sensitive applications, applications requiring extreme reliability). The cache and chip-interconnection infrastructure provides 32 MB cache per core and can scale to 32 Telum chips. The cache design has been described as "revolutionary" in 2021, by creating a system where the L2 cache of one core can be used as virtual L3 and L4 caches for another core. The Telum processor can either be water cooled or air cooled, but water cooling is required for running more than a few Telum processors in a single IBM compute drawer. Unlike other processors, the IBM Telum does not thermal throttle by reducing clock speed; instead it inserts sleep state instructions.
Telum adds a new, NNP-Data-Type-1 Format, 16-bit floating point format and several new instructions. The Neural Network Processing Assists (NNPA)
instruction performs a variety of tensor instructions useful for neural networks.
