IBM has unveiled the next generation of its Telum processor, along with a new AI accelerator called Spyre. These technologies are aimed at improving the performance of IBM Z mainframes, particularly in the areas of AI and large language models.
Telum II Processor Features According to IBM Around eight cores running at 5.5GHz, with a 40 percent increase in cache capacity compared to its predecessor. 36MB of L2 cache is available per core, resulting in a total on-chip cache of 360MB. The default L4 cache has been increased to 2.88GB per processor case. The integrated AI accelerator delivers four times the computing power of the first Telum processor. Another addition is the integrated Data processing unitwhich should speed up and simplify the processing of inputs and outputs.
In addition to the Telum II, IBM is introducing the Spyre accelerator, a PCIe card designed specifically for complex AI models. This card can hold up to 1TB of memory and consumes up to 75W maximum power. The Spyre accelerator can operate with eight cards in a standard I/O tray. Each Spyre chip has 32 compute cores that support a variety of data formats.
IBM is targeting applications such as fraud detection, anti-money laundering, and AI assistants with this new device. The combination of Telum II and Spyre is expected to improve performance in both traditional and new AI models. The Telum II processor and Spyre accelerator are expected to be available to customers using IBM Z and LinuxONE systems in 2025.
