Reuters: Nvidia tweaks flagship H100 chip for export to China as H800 (2023-03-21)

Wire-service primary reporting (by Stephen Nellis and Jane Lanhee Lee) carrying NVIDIA's own on-record statement that the H800 exists and is legally exportable to China. HOST VERIFICATION, since it is not obvious from the URL: the url host is finance.yahoo.com, not reuters.com. This is a Reuters WIRE SYNDICATION, not a reseller or mirror - Reuters licensed its own copy to Yahoo Finance, and the page carries Reuters' byline, dateline ('SAN FRANCISCO (Reuters)'), photo credit ('H100, Nvidia's latest GPU is seen in this photo in Santa Clara - Reuters') and the '(Reporting by Stephen Nellis and Jane Lanhee Lee; Editing by Richard Chang and Christopher Cunningham)' line. reuters.com's own copy of this article is live at https://www.reuters.com/technology/nvidia-tweaks-flagship-h100-chip-export-china-h800-2023-03-21/ but is not machine-readable (paywall/interstitial), which is why the syndication is the resolvable copy cited here. Publisher is therefore 'Reuters', the originating newsroom, not Yahoo. KEY EVIDENCE, and the reason no vendor spec table can exist for this part: 'A chip industry source in China told Reuters the H800 mainly reduced the chip-to-chip data transfer rate to about half the rate of the flagship H100. The Nvidia spokesperson declined to say how the China-focused H800 differs from the H100, except that "our 800 series products are fully compliant with export control regulations."' Also confirms named deployment: 'The new chip, called the H800, is being used by the cloud computing units of Chinese technology firms such as Alibaba Group Holding Ltd, Baidu Inc and Tencent Holdings Ltd, a company spokesperson said.' And the statutory reason: 'The rules around AI chips imposed a test that bans those with both powerful computing capabilities and high chip-to-chip data transfer rates.' NOTE WHAT IS ABSENT: no NVLink GB/s figure, no FP64 TFLOPS figure, no memory bandwidth, no TDP, no die/process node. NVIDIA publishes no H800 datasheet. Accessed 2026-10-03. KIND NOTE: the schema's kind enum has no 'news' member, so this wire-service report is filed as 'blog'. It is first-party reporting with named reporters and an on-record NVIDIA spokesperson, which is materially stronger than the ordinary meaning of 'blog'; treat it as wire-service primary reporting, not as an unattributed blog post.
