Imec's Approach to Thermal Challenges in AI Computing

Imec, a leading research and innovation hub based in Leuven, Belgium, has made significant strides in addressing thermal difficulties associated with 3D High Bandwidth Memory (HBM) integrated on Graphics Processing Units (GPUs). Leveraging a unique system-technology co-optimization (STCO) method, Imec's latest study explores ways to enhance performance while dramatically lowering operational temperatures. This advancement is especially critical for AI applications, where high performance is paramount.

Traditionally, thermal bottlenecks have posed substantial challenges in computer architecture, particularly for systems powered by AI workloads. In their new research, Imec has achieved an impressive reduction in peak GPU temperatures, showcasing a drop from 140.7°C to 70.8°C under realistic conditions reflective of artificial intelligence training scenarios. This remarkable feat underlines the importance of examining both system and technology factors holistically, rather than in isolation.

The study employed comprehensive methodologies that integrated both thermal management and system performance enhancements. The cross-technology co-optimization (XTCO) program played a pivotal role, enabling researchers to develop advanced compute systems that can withstand higher operational demands. Julien Ryckaert, a representative from Imec, stated, “This is also the first time that we demonstrate the capabilities of imec’s new XTCO program in developing more thermally robust advanced compute systems.”

The implications of this research are vast. As AI continues to evolve and grow in complexity, the demand for more powerful and efficient computing systems is paramount. Imec’s approach not only alleviates thermal constraints but also positions the next generation of GPU architectures to deliver superior performance densities. In doing so, it creates an opportunity for enhanced capabilities across a variety of industries.
