> "could be a huge jump" ... "maybe slower means lowering the hertz"
This is so painfully obvious it's sad that it has to be said out loud. There is no credible information about exactly what AMD means when they claim lower performance. Nothing meaningful is said about the nature of their 'protections.' And the fact that everything was supposedly blessed by all the various US government TLAs under the Obama administration is almost a confirmation of the WSJ lede; that this was yet another backdoor sellout of US tech to China.
The two key claims by AMD -- that they only transferred lower performing technology and that all the things were blessed by US government -- were cited nearly verbatim in the WSJ story. I can't find anything in the AMD statement that adds meaningfully to the case; it's a non-rebutting rebuttal.
Whatever. If they really did unzip for the Chinese military as the WSJ claims then AMD will soon find itself competing with Chinese government subsidized derivatives of their IP and have next to no meaningful recourse with any governing authority.

HAMs still do this. Messages from people isolated in Puerto Rico by hurricane Maria were relayed to the US mainland via HAM radio operators on the island. For some time that was the only thing available.
