New brain-like chip could slash AI energy use by 70%

Artificial intelligence is facing an energy crisis. As models grow larger, the electricity required to power data centers is reaching unsustainable levels. Current computing architectures suffer from the ‘Von Neumann bottleneck,’ where the constant movement of data between the processor…

Stop scaling cloud chips, Axelera AI warns: purpose-built AI wins

The edge AI market is booming, but deployments stall in "pilot purgatory." Axelera AI's CEO Fabrizio Del Maffeo explains how purpose-built Digital In-Memory Computing architecture eliminates the data bottleneck, making AI deployments at the edge economically viable.

Tamalika Banerjee: Pioneering energy-efficient AI

The University of Groningen professor and IMChip founder is developing neuromorphic chips inspired by the human brain that are up to 200 times more energy-efficient than conventional processors. Her message: interdisciplinary collaboration isn't optional—it's essential.

Green myths and platform power: How AI reshapes a climate debate

Big Tech's promises of "green AI" mask an uncomfortable reality: massive energy demands, growing carbon emissions, and a shifting narrative that sidelines sustainability. Dr. Rianne Riemens unpacks how Silicon Valley is shaping our environmental futures.
