Preparations for the release of Ryzen 3000 (Matisse) desktop processors based on the Zen 2 microarchitecture are in full swing. Therefore, it is not at all surprising that more and more unofficial details about the expected new products appear in the information environment. In anticipation of the announcement, many motherboard manufacturers are actively testing engineering samples of systems based on pre-release Ryzen 3000 and AM4 motherboards with the new X570 chipset, and this allowed the Chinese technoportal bilibili.com to collect a very informative collection of facts from knowledgeable whistleblowers.
At the same time, there is no answer to the main question yet. AMD does not disclose the composition of the Ryzen 3000 lineup for the desktop segment, and it is not known how many cores its older representatives will have. Many users expect 12- or even 16-core processors to come out, but the samples that board manufacturers currently have have only up to eight processing cores. However, this does not exclude the possibility of the appearance of processors with a large number of cores, which are being prepared in an atmosphere of strict secrecy.
At the same time, the source says that in general, the improvement in performance, which is shown by the Ryzen 3000 copies available to board manufacturers, does not look so impressive against the background of expectations placed on Zen 2. Existing third-generation Ryzen samples outperform their predecessors by about 15%, and their operating frequency has already been brought to a fairly high level. It is dynamically controlled based on consumption and heat dissipation and reaches 4,5 GHz. In addition, there are no significant improvements in the implementation of the memory controller in the new AMD processors: high-speed DDR4 modes for the Ryzen 3000, apparently, will again be unavailable.
The situation with the third-generation Ryzen platform is also not entirely smooth. Problems are caused by support for PCI Express 4.0, which, judging by the available information, will eventually be officially promised only for the flagship X570 chipset, but not for the younger version of the B550 chipset. And what's more, motherboard manufacturers even had to start redesigning their X570-based motherboards, since the first version was unsuccessful and did not provide stable operation of the PCI Express bus in 4.0 mode.
The key characteristics of motherboards based on the X570 system logic, in addition to the ability to include a processor controller for the PCI Express 4.0 graphics bus, are also called an increase in the number of PCI Express 2.0 chipset lines to 40 pieces (some of the lines from this number are shared with SATA and USB ports) and an increase in up to 8 USB 3.1 Gen2 ports.
Along the way, the source cites comments from motherboard manufacturers regarding the compatibility of future Ryzen with older Socket AM4 motherboards. It is alleged that boards based on the younger A320 chipset will most likely not receive compatibility with Ryzen 3000 processors for marketing reasons. In addition, the same fate may await boards based on the B350 chipset, but no decision has been made on them yet, and more specific information will become known later.
The release of the new X570 platform, which is positioned as the main one for the third generation Ryzen, will take place in July - simultaneously with the release of the processors themselves. The younger version of the chipset, the B550, will be launched on the market later - after about a couple of months. Recall that most of the circulating rumors refer to July 7 as the date of the announcement of the desktop Ryzen 3000. However, many details about the expected new products will probably become known already at the Computex exhibition, which will be held in early summer.
