The next generation of processors AMD’s Ryzen is expected to mark a milestone with a double jump in the burning process.
If everything goes as planned, AMD should launch its new Zen 5 architecture during this year 2024. An architecture which will logically replace Zen 4 marketed in September 2022.
From its launch, Zen 5 will be the opportunity to discover two types of hearts, Zen 5 and Zen 5c. A usual distinction at Intel, but which AMD only introduced very recently, during last year.
The Zen 4c / Zen 5c: not cheap cores
AMD then mentioned the arrival of Zen 4c cores to complement some of its processors equipped with Zen 4 cores. The main advantage of the “c” lies in their compactness which allows more to be integrated into less space.
These Zen 4c cores are designed for low power envelopes which allows them to be more robust when going below 20 watts. Conversely, they are less efficient than the Zen 4 beyond this figure, but AMD emphasizes that these are not discount cores and that their number of instructions per cycle (IPC) is identical to that Zen 4s.
In this sense, AMD clearly distinguishes itself from Intel, whose high-performance cores and efficient cores have little to do with each other: the former are much more powerful than the latter, devoted to secondary tasks.
32 Zen 5c cores in 3 nm by CCD
According to AMD, a similar distinction should be made at the release of Zen 5 with, therefore, Zen 5 and other Zen 5c cores within the same generations of chips. AMD is currently closing these processors.
TechPowerUp relays some interesting information on this subject, because if we are to believe our colleagues, AMD would have the idea of using two different engraving processes depending on the cores. Zen 5 will be an opportunity for AMD to use TSMC’s 4nm processor. So far, nothing new.
On the other hand, it would be a question of going further for the Core Chiplet Dies – main unit of a Ryzen processor – in Zen 5c. We are indeed talking about the 3nm process from the same TSMC. In either case, we are talking about going into mass production for the second quarter of 2024.
Still according to the sources of TechPowerUpa Zen 5c CCD could thus consist of two CCXs of 16 cores each, for a total of 32 cores with 1 MB of L2 cache per core and 64 MB of shared L3 cache.
