HEDT processors are nothing more than server processors geared towards what we call workstations, which are PCs used in work disciplines where the power of a desktop processor is not sufficient, such as This is the case with professional video editing. Threadripper processors have been AMD’s bet in this market for years.
The AMD Threadripper 5000 Chagali are just around the corner
Thanks to MoePC, we learned that AMD could launch its Thredripper 5000 next August, so it would only take a few weeks to see it on the market. Which is still an evolution similar to what we have seen from Ryzen 3000 to Ryzen 5000, from EPYC 7002 to EPYC 7003. Designs in which the central I / O Die which encompasses the hardware in charge of the communication between Chiplets CCD and these with RAM and peripherals.
What at first glance, it would be enough for AMD to use the same central I / O Die for Zen 2 and Zen 3. But it is not exactly like that, since the I / O Die of the Ryzen 5000 has been improved for supports faster DDR5 memories. In the case of EPYC and Threadripper, XGMI interfaces have seen their speed drop from 16 GT / s to 18 GT / s.
The xGMI interface is an external interface based on the PCI Express protocol which allows the different chips to be interconnected. 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 Chagali Threadripper 5000 will support DDR4 memory at a higher speed than the Threadripper 3000. Which will mean an increase in performance improvement. To which must of course be added the use of CCD Chiplets with Zen 3 cores, which represents a further increase in performance.
AMD continues to lead the HEDT CPU market
With Intel completely out of the HEDT CPU market, and despite reports of the next generation of its Xeons for 2022, AMD is completely alone in this market, with which Threadripper 3000 remains the most powerful processor in this segment. The interest of launching Threadripper 5000 Chagali? AMD is phasing out the core Zen 2 chips 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 to carry since Zen 2, hence the sockets comparison. This also concerns the memory interfaces and the peripherals used, common between Zen 2 and Zen 3. This allows them to use the TXR4 socket of the Threadripper 5000 Chagali.
We can not forget, and finally, that although Zen 4 will be launched next year, it is very likely that for Threadrippers based on this architecture we will not see them before 2023 and AMD needs to have something compete with the Sapphire Rapids HEDT in the event that Intel launches them in the market in 2022.
