As you know, in the Ryzen 7000 processors, AMD continued to use the chiplet design. Younger models with up to 8 cores are content with one chiplet, while more “nuclear” ones have a couple of them. It turned out that this is not a reinforced concrete rule. An unusual copy of the Ryzen 5 7600X fell into the hands of enthusiast Roman “der8auer” Hartung.
The unusual Ryzen 5 7600X has a pair of chips with cores under the lid, which means that Ryzen 9 7900X and Ryzen 9 7950X rejection is used for their production. One of the chiplets is completely deactivated, while the second has 6 of the 8 cores enabled. In other words, there is no difference between the dual-chip and “regular” 7600X, including inter-core delays and memory access delays.
In fact, this approach has been used quite often and for a long time. Seasoned enthusiasts may even recall the possibility of unlocking hidden cores. Unfortunately, one cannot hope for such an auction of unprecedented generosity; this shop was closed 10 years ago.
