San Jose, CA — There is no longer any misunderstanding about the Nvidia RTX 4090D “Dragon” and H20 GPUs. Contrary to what was said earlier, the new and improved U.S. sanctions do not affect these already shipped GPUs that are in line with the sanctions1.
The Story of Sanctions
The U.S. put out a paper explaining current sanctions, which made people worry at first about what would happen to Nvidia’s GPUs. The new paper, on the other hand, has “Corrections and Clarifications” about export controls, mainly about weighted teraflops (WT) and adjusted peak performance (APP). The 4090D and H20 GPUs are within the allowed ranges1.
What’s Still the Same
The 4090D is a less powerful version of the RTX 4090. It has 14,592 CUDA cores and a 425W TBP. It has 12.8% fewer CUDA cores and a 5.9% lower TDP than the one that came before it. The H20, which is another GPU that doesn’t break bans, is also unaffected1.
What the Tech Says
The rules only cover computer systems, not individual GPUs. Memory consistency is very important, and the changed peak speed is based on FP64 flow. Vector processors and scalar processors are both taken into account in the weighted teraflops estimate. For the most part, the 4090D and H20 GPUs meet the requirements set by U.S. law1.
A Look Ahead
Even though the latest explanation is helpful, Nvidia is still coming up with new ideas. The M3 Ultra, which is said to be a single chip, is still waiting to be shown off. As technology changes, producers still have to find the right mix between performance and compliance12.
