The creator of DRAM Calculator speculates that the newer AMD Ryzen Threadripper 3000 will not be supported on current X399 motherboards.

Many users are looking forward to AMD Ryzen Threadripper 3000 processors. These new processors will compete with the Intel Core-X, offering more power and cores for less price. The new Threadripper processors will use the same socket but three new chipsets. Everything suggested that there would be compatibility with the X399 chipset when sharing socket. According to the creator of DRAM Calculator, there will be no support for the X399 chipset.

But it seems that AMD has changed plans drastically. As we already know, there will be three new chipsets, the TRX40, TRX80 and WRX80. The company intends to divide these new processors into three segments according to the needs of the users. By making a drastic change to the chipset, compatibility with 'old' motherboards will be lost, according to the creator of DRAM Calculator.

AMD Threadripper 3000 will not have support for X399 motherboards

Within the Guru3D forum, '1usmus', creator of DRAM Calculator has said that the Threadripper 3000 would have a redesign on the pins. Although they are based on Zen2 @ 7nm, it seems they have had to make major changes. One of these would be due to PCIe 4.0 support and another to a new memory controller.

"Hey. Unfortunately there is not very good news, AMD has changed its mind about the compatibility of X399 with the new generation. For this reason, HEDT disappeared from all calendars and the release of these processors was forced to postpone it ”, 1usmus has said in the Guru3D forum.

He further adds: “As the new processor has a new memory controller, the pins had to be seriously changed. Additionally, the new PCI Gen 4 standard and new power connections have contributed to this decision. TRX40 and TRX80 are a new generation and a new architecture. It has nothing to do with the past generation.

At the moment, all the information is classified and I do not have access to it. "

We will see in the coming weeks whether or not this information is confirmed. With the creation of the TRX40, TRX80 and WRX80 chipsets, it was intended to divide the range into three different solutions. There is even talk that the WRX80 could be a hybrid between Threadripper and EPYC, although who knows.
