Intel Alder Lake 12th-generation Core is the first in the x86 mainstream field, commonly known as the “large and small core” hybrid architecture, and according to the exposure, AMD Zen5 and Zen4D will also be combined.

According to the latest statement from the hardware exposure expert @Greymon55, the AMD Zen5-based desktop Ryzen product codenamed “Granite Ridge” uses 3nm and 6nm processes, of which 3nm naturally corresponds to the CCD computing part, and 6nm corresponds to the IOD input and output part, or Small chip design.

The Ryzen product of Zen5+Zen4D hybrid architecture is “Strix Point”, using 3nm and 5nm processes.

This is a bit confusing. It seems that 3nm corresponds to Zen5, 5nm corresponds to Zen4D, so what about the IOD part? Continue the 6nm process? Then there are three processes at the same time.

As for the newly announced Zen4c architecture, @Greymon55 said it is not the same thing as Zen4D. Zen4c is for cloud services (cloud), and Zen4D is not sure what it stands for, it may be dense.

According to previous news, Zen4D will completely redesign the cache system on the basis of Zen4 (three buffers may be less than half), simplify some functional features, reduce frequency and power consumption, and the final result is to sacrifice part of single-threaded performance in exchange for better performance Multi-threaded performance, and supports AVX512 instruction set, DDR5 memory, and the core area is similar to Zen4.

Its corresponding server Xiaolong product code name is “Bergamo” (Bergamo, a city in northern Italy). Each small chip integrates 16 cores, which is twice as many as it is now, with a maximum of 128 cores as a whole. It is expected to be released in the second quarter of 2023.

Zen5 claims to be comparable to the improvement between Zen and Zen2. Compared with Zen4, IPC co-frequency performance is expected to increase by as much as 20-40%. The birth time is expected to be in the fourth quarter of 2023.

The hybrid architecture product of the two is currently planned to include 8 Zen5 cores and 16 Zen4D small cores, for a total of 24 cores. If both support multi-threading, it will be 48 threads.
