The SoC of PS5 was photographed for the first time with a certain level of detail, and apparently, the shots reveal the lack of certain features typical of Zen 2, in particular, some Floating Point Unit and Cache Infinity.
After the various discussions (and the inevitable controversies) related to the fact that PlayStation 5 would not be a fully RDNA 2 platform, the question, therefore, shifts to the CPU, which as a custom is necessarily distinguished from the standard processors of the AMD series.
According to a first analysis carried out on Twitter by a user who obviously knows what he is talking about, this Locuza, the absence of the Infinity Cache and the L3 cache unites PS5 and Xbox Series X/S, given that not even the next-gen Microsoft console has maintained this endowment.
What exactly is Infinity Cache? This is an AMD technology that uses a cache matched to the GPU in an extremely similar way to what happens with the L3 cache of processors. This memory, equal to 128 MB, allows the graphics sector to manage operations without calling into question the RAM.
That said, it seems that Sony used a 128-bit bus instead of 256 for the aforementioned Floating Point Units, which would inevitably decrease their performance. We are talking about mathematical coprocessors that are used precisely for floating-point calculations.
The WGP, that is the workgroup processors, finally seem to be organized on the SoC as happened with the RDNA 1 architecture, but also in this case it is a solution that unites PS5 and Xbox Series X | S.
In short, these first detailed photos help to understand how both Sony and Microsoft have designed the main components of their new consoles, although it is not yet clear how many and what implications this may have on the power of the machines.
