Curiosity is something that makes many people do things that normally no one would consider, such as opening a chip to find out what is inside, and even more so if we take into account the prices that some of these products can have. But there are also people who can afford to do this, and several users allow us to know what the chips of amd because they have published several high-quality die-shots, offering the possibility of seeing how they are structured and what components the chips include Granite Ridge in it inside.
It is normal for us to ask ourselves on many occasions what is behind the creation of a chip, and it is not easy to identify each of the components that a processor may have, even if we have a series of high-resolution photos due to the complexity. that have these types of developments. But even so, it is something that can catch our attention, even if we do not know too much about each of the components that are integrated into the chip, since it is something really curious, and even more so if we think about how small each one of them is. .
AMD’s Granite Ridge processors revealed, this is what they have inside
A CPU is made up of a large number of components, but we generally cannot see them because they are covered to prevent problems, mainly temperature and other aspects that can easily damage them. But this time, Nemez, Fitzchens Fitz and HighYieldYT offer us the ability to have a detailed view of what the chips look like Granite ridge of amdas they have published several high-resolution photos of an 8-core CPU based on the Zen 5 architecture.
First of all we can see that the appearance is quite similar to those of the Raphael chips, with the big difference that Zen 5 is an architecture that uses a 4nm node, the N4P from TSMC. Granite Ridge has two CCDs that are really close to each other, remember that each of these components contains 8 full-size Zen 5 CPU cores, each having 1 MB of L2 cache and with a central L3 cache (as as can be seen in the image) of 32 MB that are shared by the eight cores, with the only remaining components being the system management unit (SMU) and the Infinity Fabric over Package (IFoP) PHYs, which connect the CCD to the cIOD.
There are parts that are generally very similar to those that the Raphael had as we have indicated, the iGPU for example is based on the RDNA 2 graphics architecture and has a single work group processor (WGP) for two calculation units (CU) or 128 stream processors, with the I/O die being extremely similar to the previous generation. The most notable thing is as we can imagine the size of the cores, which are larger because AMD has improved aspects such as the 512-bit floating point data path and more.
