IBM is releasing the latest version of its mainframe hardware that includes new updates meant to accelerate AI adoption. The hardware and consulting company on Monday announced IBM z17, the latest version of its mainframe computer hardware. This fully encrypted mainframe is powered by an IBM Telum II processor and is designed for more than 250 AI use cases, the company says, including AI agents and generative AI. Mainframes might seem like old hat, but they’re used by 71% of Fortune 500 companies today, according to one source. In 2024, the mainframe market was worth an estimated $5.3 billion, per consulting firm Market Research Future. The z17 can process 450 billion inference operations in a day, a 50% increase over its predecessor, the IBM z16, which was released in 2022 and ran on the company’s original Tellum processor. The system is designed to be able to fully integrate with other hardware, software, and open-source tools. Tina Tarquinio, VP of product management and design for IBM Z, told TechCrunch that this mainframe upgrade has been in the works for five years — well before the current AI frenzy that started with the release of OpenAI’s ChatGPT in November 2022.
