IBM has introduced a new CPU for its Z Series mainframe that’s designed for transactions like banking, training, insurance, customer interactions, and fraud detection.
The Telum processor was unveiled at the annual Hot Chips conference and has been in development for three years to provide high-volume, real-time inferencing needed for artificial intelligence.
The Telum design is very different from its System z15 predecessor. It features 8 CPU cores, on-chip workload accelerators, and 32MB of what IBM calls Level 2 semi-private cache. The L2 cache is called semi-private because it is used to build a shared virtual 256MB L3 connection between the cores on the chip. This is a 1.5x growth in cache size over the z15.
