Recently, NVIDIA ceased the shioment of high-performance GPUs to countries like China. The new U.S. restrictions aimto curb the utilization of powerful accelerators for specific tasks, particularly in machine learning and its potential usefor military applications. This led to the export ban of cards such as H100, A100, and their 800 variants, originallydesianed to navigate previous restrictions, Notably, the updated rules shift the focus from interconnectcommunications between GPUs to compute power, impacting not only data-center GPUs but also gaming cards likeRTX 4090.

In response, NVIDIA has introduced a fresh series of data-center GPUs designed to comply with the newrestrictions. The HGX H20 and L20 series are now offcially available to Chinese customers, featuring reduced computepower compared to their predecessors. The H20 GPU boasts 96GB of HBM3 memory with a memory bandwidth of 4.0TB/s. Interestingly, that's higher bandwidth than the 'global' H100 with 3.6 TB/s.

0n the other hand, the L20 GPu, based on an AD102 GPU, is equipped with 48GB of GDDR6 memory. These solutionsintentionally limit compute capabilities to ensure GPUs do not exceed 4800 TOPS performance.

The HGX H20, a data-center GPU optimized for clusters of 8 GPUs, features NVLink connectivity and demands 400W ofpower, The L20 and L2 GPUs, operating on PCle interface, offer memory options of 48GB and 24GB.Reports indicate that NVIDIA has initiated chip samplina to partners. with orders set to commence from November 16thcoinciding with the fullimplementation of U.S. restrictions. NVIDIA anticipates the first shipment to take place in December.
