Introduction: The New Era of Mainframes
In an era increasingly dominated by cloud computing, edge AI, and digital transformation, the mainframe might sound like a relic of the past. However, IBM is redefining what’s possible with its latest innovation: the IBM z17. Engineered with AI at its core, this new mainframe delivers the power, scalability, and future-proofing that businesses need to stay competitive.
Introducing the IBM z17 Mainframe
On April 8, IBM announced the launch of its next-generation mainframe, the IBM z17. Powered by the advanced IBM Telum II processor, the z17 is fully encrypted and optimized for over 250 artificial intelligence (AI) use cases, including AI agents and generative AI applications.
Unlike its predecessors, the IBM z17 is purpose-built to support modern AI workloads, bridging traditional enterprise computing with the innovations of tomorrow.
“We don’t know what we don’t know about what’s coming, so the possibilities are unlimited,” said Tina Tarquinio, VP of Product Management and Design for IBM Z, during an interview with TechCrunch.
Why Mainframes Still Matter in 2025
Despite perceptions of being “legacy” technology, mainframes remain a critical part of today’s enterprise infrastructure.
According to recent research, 71% of Fortune 500 companies still rely on mainframes to power their mission-critical operations. In 2024 alone, the mainframe market was valued at $5.3 billion (Market Research Future)—a testament to its enduring relevance.
From banking to healthcare to supply chain logistics, the mainframe is not just surviving—it’s thriving by evolving alongside technological trends like AI and hybrid cloud environments.
Key Features and AI Capabilities of IBM z17
Massive AI Processing Power
The IBM z17 is a powerhouse when it comes to AI inference, capable of processing 450 billion inference operations per day—a 50% increase over its predecessor, the IBM z16.
This significant leap is thanks to the integration of 48 IBM Spyre AI accelerator chips at launch, with plans to double that capacity to 96 accelerators within the next year.
Such performance allows businesses to deploy complex AI models directly within their IT environments, minimizing latency and maximizing data security.
Full System Integration
IBM has engineered the z17 to seamlessly integrate with a variety of hardware, software, and open-source tools.
This interoperability means enterprises can leverage their existing investments while future-proofing their operations for evolving AI demands.
The z17’s design not only supports today’s AI frameworks but is flexible enough to accommodate next-generation models that demand more local memory and compute power.
Built for the Future: Adaptability and AI Agility
IBM’s forward-thinking approach is evident in how the z17 was built to embrace AI’s rapid evolution.
Over 2,000 research hours and feedback from more than 100 customers went into designing a system with “headroom”—extra processing, storage, and memory capabilities—ensuring that as AI models grow larger and more complex, the z17 will be ready.
By adopting agile AI hardware, businesses can remain nimble, avoiding costly upgrades every few years as their AI needs scale.
Energy Efficiency and Sustainable Performance
Sustainability is no longer optional—it’s a business imperative.
IBM’s z17 mainframe boasts a seven-and-a-half-fold increase in AI acceleration efficiency while consuming five-and-a-half times less energy compared to multi-modal setups on other platforms.
This innovation not only reduces operational costs but also aligns with broader ESG (Environmental, Social, Governance) goals many enterprises are prioritizing today (learn more about ESG in tech).
