AMD Ryzen 5 7600X and AMD Ryzen 7 7800X are coming in September

Posted by Stefan on 2022-06-20

After we published a performance assessment of the AMD Ryzen 9 7950X last week, the well-known AMD leaker Greymon55 has now posted more informations via Twitter.

He predicts the first four models of the new Zen 4 desktop generation, which AMD would like to present at the end of 2022. There is also an alleged release date of September 15, 2022.
