Transferring lower speed tech still could be a huge jump from what China had, the main point is architecture is hard to put a value to it. For what is known, 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.
Otherwise they would not have a single chance to bring in anybody of an anymuch high calibre to China
