The market does not like emptiness, and the competition cannot sleep without reacting properly to the steps of its biggest rivals. Technology companies like Intel, AMD or NVIDIA are a great example of this and we have again confirmed this, as information about Zen4D, the energy-saving equivalent of Zen4 cores, has appeared.
AMD Zen4D, or energy-saving conversion of Zen 4 cores
As a reminder, I will only mention that the next generation Intel processors have introduced a heterogeneous structure of the cores. It all comes down to combining two types of cores in one processor – the efficient ones, which do not take into account the energy consumption, and the energy-saving ones, the most important role of which is to maintain the best ratio of efficiency to the watts used. Intel refers to them sequentially as Performance Core i Efficiency Corewhich are based on the architecture respectively Golden Cove i Gracemont.

AMD, on the other hand, does not have such a thing … but it has to react to this move somehow in order to be able to offer similar opportunities to its customers, and this is clearly what it is aiming for. We take this information from the Moore’s Law is Dead YouTube channel, according to which the creators of AMD are developing a new type of microarchitecture known as Zen4D (Dense). This one is to be a power-saving Zen 4 core with a lower clock speed and a smaller cache size.

In practice, this means that AMD will have access to two cores with a completely different application, and in the case of Zen4D, as many as 16 cores in one chiplet can be played. The first processor with these cores is to be the putative 128-core EPYC processor. The issue of multithreading remains unknown, as well as the possibility of combining both cores on one processor. However, we are looking forward to the APU Strix Point in the future with Zen 5 and Zen4D on one board.
