In the Ryzen 7000 (Raphael) processors, AMD continued to use a multi-chip layout, combining a 6-nm I/O IOD crystal and up to two 5-nm CCD chiplets with Zen 4 cores on a single PCB. pieces are traditionally managed with one chiplet, but, as it turned out, not always. Among them was a sample of the Ryzen 5 7600X, which fell into the hands of the German overclocker Roman “der8auer” Hartung.
As a reminder, the AMD Ryzen 5 7600X is a 6-core/12-thread Zen 4 processor with 32 MB of L3 cache and a clock speed of 4.7 to 5.3 GHz. Having removed the heat-spreading cover, der8auer found two CCD-crystals, that is, initially this copy of the Ryzen 5 7600X was supposed to be the Ryzen 9 7900X or Ryzen 9 7950X. In the final product, one of the chiplets was completely deactivated, while six of the eight Zen 4 cores remained active on the second.
Unfortunately, there is no need to talk about unlocking additional cores, as was the case with old AMD processors. The above Ryzen 5 7600X scalping experiment sheds light on the chipmaker’s inner workings and what happens to defective Ryzen 9 CPU samples. It doesn’t matter to the end user how many CCDs are under the hood of 6-/8-core Ryzen 7000 CPUs.
