While advanced GPUs like the A100 excel at running the computationally intense training phase for neural networks, purpose-built AI inference chips like IBM’s Telum optimize delivering results from already trained models in real time. Telum is a bold new processor architecture designed from scratch just for enterprise-scale AI workloads.

Each Telum chip contains eight powerful Arm CPU cores clocked at an astounding 5.5GHz frequency. By combining leading-edge 7nm transistor technology with innovative system-on-chip (SoC) design, Telum achieves blazing fast throughput with low power consumption.

But one of Telum’s most impressive capabilities is its scalability. Using IBM’s advanced wafer-scale engine technology, up to 32 Telum chips can be seamlessly linked together into a single system with shared memory. This allows the processor to deliver incredible AI performance rivaling that of over 16,000 laptops in the space of just a 2U server.

According to IBM benchmarks, Telum provides up to 40% faster response time for AI inferencing requests versus competing solutions. This high-speed inferencing enables advanced applications in finance, healthcare, telecommunications and more that demand real-time AI-powered decision making. By handling inferencing directly on the chip instead of shuttling to a separate GPU or CPU, Telum removes latency while improving efficiency.

Intel Loihi 2: Pioneering Neuromorphic AI Chips

While most AI chips utilize traditional computer architectures, Intel’s Loihi 2 processor represents an entirely new paradigm known as neuromorphic computing. Instead of numerical calculations, neuromorphic chips work by mimicking the behavior of the human brain using networks of artificial neurons and synapses.

This neuro-inspired approach allows Loihi 2 to naturally learn by observing data from sensors and continuously self-adapting like biological brains. Rather than needing to be trained on huge datasets like neural networks, Loihi 2 can incrementally learn from real-world experiences more efficiently.

The Loihi 2 architecture comprises three reticle chips manufactured on Intel’s cutting-edge 4nm process. With over 100 billion transistors integrating processor cores, memory, and interconnects, Loihi 2 delivers substantial gains versus its experimental predecessor.

According to Intel, Loihi 2 processes information up to 1,000 times faster and 10,000 more efficiently than traditional chips for specialized workloads like sparse coding and graph search. This presents new possibilities for autonomous robotics, real-time monitoring, and other applications benefiting from quick reaction and adaptation.

While still an emerging technology, neuromorphic innovation could unlock brain-like capabilities far surpassing current AI — a prospect that fuels intense interest from researchers. Intel provides Loihi 2 as an open-source platform for scientists to advance new algorithms leveraging its unique capabilities.
