It’s no secret that AMD intends to release Ryzen 4000 series desktop processors (Vermeer) by the end of the year – they will switch to a very promising Zen 3 architecture and use a more advanced 7nm + process technology, but at the same time they will retain the AM4 performance and 16 cores in the maximum configuration. New information indicates that models with 10 physical cores may appear in the new line of Ryzen desktop CPUs (the Ryzen 3000-series line, recall, includes “stones” with four, six, eight, twelve and sixteen cores).
One of the key innovations in the AMD Zen 3 architecture will be the move to 8-core CCX modules with 32MB of L3 cache, which should provide lower latency when accessing the L3 cache and better interaction between the cores. According to preliminary data, the new Zen 3 architecture will provide an increase in IPC (instructions per clock) by up to 15% or even more compared to Zen 2. In addition, Ryzen 4000, which will be produced at TSMC facilities at 7nm +, will retain backward compatibility with older B450, X470 and X370 motherboards (the newer B550 is of course also supported).
The possibility of the appearance of 10-core models in the future Ryzen 4000 line is indicated by the corresponding lines of code in the fresh AGESA firmware 18.104.22.168. They were discovered by a well-known Ukrainian enthusiast and creator of the popular Ryzen DRAM Calculator utility Yuriy “1usmus” Bubliy. For clarity, confirmation of the existence of such models does not guarantee their release at all, but the probability of this event is quite high. If AMD ultimately decides to directly respond to 10th generation Intel Core 10-cores (Comet Lake-S), then the configuration of such CPUs could include two 7nm chiplets with Zen 3 processor cores, combined in a “5 + 5” scheme.
Also, the Ukrainian enthusiast managed to find information about several more features of the new generation. In particular, he announced the new overclocking function Curve Optimizer, which will allow you to adjust the frequency and voltage for each processor core without restrictions, and the technology for accelerating RAM through the Infinity Fabric dividers.
Tests of engineering samples of the Vermeer CPU have appeared on the network more than once – some instances even conquered the frequency of 4.9 GHz, which is 200 MHz more than the current flagship Ryzen 3000.
The older Ryzen 4000 models are expected to hit the market first, and the more affordable 4th Gen Ryzen CPUs will have to wait until next year. Previously, there were also rumors that AMD could break the logical sequence and release the Zen 3 desktop processors to the market called Ryzen 5000, skipping the Ryzen 4000 in order to close the series number lag behind mobile desktop APUs.
