NVIDIA'S DELAYED BLACKWELL AI CHIPS ARE OVERHEATING IN SERVERS

Summary from the TLDR newsletter

Nvidia's upcoming Blackwell GPUs are prone to overheating when connected to each other on server racks. The issue is due to the server rack designed for Blackwell, which can connect up to 72 GPUs at a time. The racks have been redesigned, but this could cause further delays. Nvidia originally said that the GPUs could ship as soon as Q2 2024 before it encountered challenges.
