CNBC: U.S. curbs export of more AI chips, including Nvidia H800, to China (2023-10-17)

Secondary reporting on the US October 2023 rule change that closed the H800 export loophole. TWO REASONS THIS SOURCE IS HERE. (1) It establishes that the reduction was INTERCONNECT-ONLY, which is the load-bearing fact for the accelerator record: 'Instead, Chinese companies were able to buy a slightly slowed-down version called the H800 or A800 that complies with U.S. restrictions, primarily by slowing down an on-device connection speed, called an interconnect. The new rules will ban those chips as well, senior administration officials said in a briefing with reporters.' The word 'primarily' is doing work and is not upgraded to 'exclusively' anywhere I could reach. (2) It dates the supply cutoff, which is why the H800 is a used-market part and not a current product: 'The new export restrictions will restrict the export of Nvidia's A800 and H800 chips, senior administration officials said.' KEY POINT FOR THE RECORD: this article contains NO FP64 figure, NO NVLink GB/s figure and NO memory bandwidth figure for the H800, and searches across multiple engines turned up no source that does. KIND NOTE: filed as 'blog' because the schema's kind enum has no 'news' member; it is a named-reporter news article with senior-administration-official sourcing, which is stronger than the ordinary meaning of 'blog'.
