Microsoft, Meta and more might have to wait for their shiny new AI hardware as Nvidia's Blackwell server GPUs are reportedly delayed

pcgamer.com:

Another day, another delay. This time it looks like it's Nvidia's Blackwell AI GPUs that may have fallen victim to last minute delay-itus, as reports now suggest they'll be launching in the first half of 2025 instead.

While engineering samples for the B100 and B200 GPUs have already been delivered, it seems enterprise customers including Microsoft, Meta and xAI might have to wait for their orders. According to Tom's Hardware, two anonymous sources who worked on the chips first released news of the pushback, which was later allegedly corroborated with an anonymous Microsoft source by Bloomberg.

Previously, it was thought that Nvidia was aiming for an end of 2024 release. With multiple high-profile customers placing huge orders for Nvidia's latest mega-GPUs, and prices estimated to run at $70,000 per «superchip», significant delays are not likely to be well received.

While these sources have pointed at design flaws as a reason for the pushback, Dylan Patel, Chief Analyst at independent research company SemiAnalysis, has posted a tweet telling a different story. 

According to an update sent out to SemiAnalysis' clients on July 22, CoWoS-L (Chip on Wafer on Substrate) ramping issues are primarily to blame, with TSMC's AP3 packaging fab needing to be shut down to convert from CoWoS-S production to CoWoS-L.

This process is not expected to be completed until the second quarter of next year. The tweet also mentions rumours about overheating and firmware issues, but characterises them as «overblown». While the update mentions a variety of «teasing pains to be fixed», SemiAnalysis seems to think that they are not the primary cause of the delays.
