The AMD Threadripper 5000 are in the making, what are their improvements?

HEDT CPUs are nothing more than server processors oriented to what we call workstations, which are PCs that are used in work disciplines where the power of a desktop CPU is not good enough, as is the case of the professional video editing. Threadripper processors have been AMD’s bet for this market for years.

The AMD Threadripper 5000 Chagali are just around the corner

Through MoePC, it has been learned that AMD could launch its Thredripper 5000 the following August, so it would only be a few weeks to see it on the market. Which is still a similar evolution as we have seen from Ryzen 3000 to Ryzen 5000, from EPYC 7002 to EPYC 7003. Designs in which the central I / O Die that encompasses the hardware in charge of communication between the CCD Chiplets and these with the RAM and peripherals.

From what at first glance, it would be enough for AMD to use the same central I / O Die for both Zen 2 and Zen 3. But it is not exactly like that, since the I / O Die in the Ryzen 5000 was improved to support faster DDR5 memories. In the case of EPYC and Threadripper, xGMI interfaces have seen their speed increased from 16 GT / s to 18 GT / s.

The xGMI interface is an external interface based on the PCI Express protocol that is used to interconnect the different chiplets with each other. Since in architectures based on AMD Zen processors the performance of the I / O Die depends on the speed of the external memory. This means that the Threadripper 5000 Chagali will support DDR4 memory at a higher speed than the Threadripper 3000. This will mean an increase in a performance improvement. To which must be added, of course, the use of CCD Chiplets with Zen 3 cores, which means a further increase in performance.

AMD continues to dominate the HEDT CPU market

With Intel completely out of the HEDT CPU market, and despite reports about the next generation of its Xeons for 2022, AMD is completely alone in that market, with which Threadripper 3000 remains the most powerful processor in that segment. The point of launching Threadripper 5000 Chagali? AMD is phasing out Zen 2 core chiplets at TSMC factories, so the Threadripper 5000 also represents AMD’s complete transition from Zen 2 to Zen 3.

AMD designed the transition to Zen 3 to be the easiest thing to carry from Zen 2, hence they compare socket. This also has to do with the memory interfaces and the peripherals used, which are common between Zen 2 and Zen 3. This allows them to use the TXR4 socket in the Threadripper 5000 Chagali.

We cannot forget, and to finish, that although Zen 4 is going to be released next year, it is very likely that for the Threadripper based on this architecture we will not see them until 2023 and AMD needs to have something to compete against the Sapphire Rapids HEDT in the event that Intel launches them on the market in 2022.
