According to the information on the slide, the date reported would not refer to a paper launch but to the day in which the AMD CPUs will begin to be sold, while the event itself would have taken place in China, at least according to the characters written in simplified Chinese. Added to this are new rumors published by the insider Greymon55, who listed a series of possible 4 models that should make up the launch lineup.

In addition to the early models, Greymon55 also gave some indication of the price regarding the Ryzen 9 7950X, although the post was deleted later. The most powerful CPU is expected to cost 5999 yuan (€ 851.82 at the exchange rate), which is lower than the 5950X's initial launch figure. However, rumors about pricing remain something to rely on little, especially three months after the hypothetical launch of the new AMD processors. All that remains is to wait for the next few weeks for confirmation.
