Nvidia's H20 Chip in Turmoil: Supply Chain Uncertainty and Performance Scrutiny

Reports have emerged claiming difficulties among some manufacturers in placing orders for Nvidia's H20 chip, specifically designed for the Chinese market. Insiders indicate that Nvidia has stopped accepting new H20 orders since last month, though no formal announcement has been made. Despite this, some channels have reported receiving large H20 shipments exceeding the annual forecast of 40 million units.

Industry observers suggest that whispers of a potential H20 sales halt have circulated for some time. However, Nvidia continues efforts to keep the product available. Meanwhile, the H20 chip has been described by several industry participants as lacking desirability, with its performance and design seen as compromises to comply with US export restrictions.

The H20, a tailored variant of Nvidia's robust H100 chip, offers downgraded specs, including a 41% reduction in GPU cores. This has affected its overall performance, which some compare unfavorably against the full-fledged H100 variant. The H20 is equipped with 96GB of HBM3 memory and a bandwidth of up to 4.0TB/s, designed purely for AI acceleration tasks.

Conversations with various supply chain players reveal concerns over the pricing and practical value of the H20, leading to mixed interest levels. Despite the clouds surrounding its future, Nvidia has not publicly commented on these speculated supply chain tweaks or potential embargoes.

As the semiconductor landscape faces renewed scrutiny amid regulatory challenges, Nvidia's strategic positioning in China remains in the balance. The rapid, unforeseen influx of H20 units into the market hints at frenetic calculations by stakeholders ahead of potential policy shifts that could redefine the operational canvas for Nvidia's regional offerings.
