Two main aspects, two totally different architectures in the cores also based on different general architectures. AMD again seems to be taking a different path and sort of emulates what Intel is doing with its desktop and laptop processors. Is this a successful strategy? We will see him.
AMD Granite Ridge and STRIX Point, this will be the new Ryzen 8000
Granite Ridge, absolutely correct https://t.co/dogCuCZR3C

As we are well aware, the next Lisa Su desktop processors will be called Raphael and we now know the code name of the successor of this architecture: Granite Rigde. There is hardly any information on these new processors, it is too early, but it seems to have been confirmed that they will be compatible with the AM5 platform
It is also reported (in what is a leak, nothing official of course) that these processors will be similar to those from Intel, since they will integrate RDNA iGPU into their matrix for the first time. Therefore, as happens for example with Intel processors, these are high performance APUs that are badly called processors to try to differentiate them from APUs and their low end market.
Therefore, AMD will have cores of CPU + iGPU at Granite Ridge corresponding to Intel’s bet, so the swords will be high, because by then the Blues will, in theory, have the second generation of their Xe graphics. Will AMD RDNA 2 be introduced in these iGPUs?
AMD STRIX Point, Alder Lake competition or a different bet?
What is Granite Ridge?

There is also not much information about this new architecture, but it is reported that it will be hybrid, where at most it will have two IPs with Zen cores. The main cores would be Zen 5 architecture and the rest would be Zen 4.
The most interesting thing is that the two architectures will be protected and lithographed in the new node of TSMC at 3 nm, which surprised locals and foreigners. And that’s because Zen 4 will hit 5nm, so you’re APU STRIX point they would be more energy efficient than the original Raphael processors.
It is also said that the Zen 4 cores could be a vastly improved version, without becoming Zen 5 and that they will be part of the low power and power cores, now called Zen 4D.
The overall number of cores would therefore be quite curious: 8 high performance Zen 5 cores and four low consumption Zen 4D cores.
Finally, rumor has it that there will be a L4 like a swap cache, which could well be a Infinity fabric for iGPU. And it is that AMD could use TSMC’s X3D technology for the first time in STRIX Point, matching or approaching Intel in this section as well.
On the other hand, there is nothing clear about the IPC section, but given the changes, we should also face a very big jump in this section, since all the back-end and the front -end, hierarchies and records will be totally new in these Ryzen 8000 by pure logic.
