They tear down an AMD Ryzen 5 5600X to see its internal construction

The new AMD Ryzen 5000 processors, in addition to being great for gaming, have an updated design. Hardwareluxx colleagues wanted to disassemble a Ryzen 5 5600X and show what the Zen3 are like inside. Unfortunately the processor has ended up being unusable after cutting. But it's worth it to see how this Zen3 architecture processor was built.

One of the main features of Zen3 is a redesign of the cores as well as the layout of the cache. This and the 7nm + lithography that increases the density, have achieved that the Ryzen 5000 have a CPI 19% higher than the Ryzen 3000. In addition, higher frequencies are achieved, to compete in gaming with Intel solutions.

So are the AMD Ryzen 5000 processors inside

Specifically, the guys at Hardwareluxx have tested the Ryzen 5 5600X. This 6-core, 12-thread processor works at a base frequency of 3.7GHz and reaches 4.6GHz in Boost mode. Indicate that in all cores the maximum frequency is 4.2GHz.

The images that they have taken of this processor allow to see all the electronic design of the processor. We can see the composition of the I / O DIE as well as the CCD that integrates 8 Zen3 cores. For this processor, two of the cores have been disabled, we assume that the furthest from the cache.

We can see that the processor PCB is already designed to house a second CCD. Clearly the same design is used for both this processor and the Ryzen 9 that have 12 cores and 16 cores.

These Ryzen 5000 processors have a multi-silicon design, with the cores and cache on a chip called CCD and then another chip that is the I / O, which among others, manages the RAM and PCIe 4.0. This design reduces the latencies that existed in the company's early processors and made them perform so poorly. The CCDs are manufactured in 7nm and the I / O DIE is manufactured in 12nm, allowing to reduce costs.
