AMD announces Threadripper Pro 5000 WX (Zen 3) line with up to 64 cores and 128 threads

Some of the highlights are Zen 3 microarchitecture, higher clocks and IPC improvements

THE OMG today announced the availability of new professional processors wire cutter Chagall Pro 5000 WX for OEMs and partners working with systems integration. In this way we can comment on the specifications of the new line, highlighting the Zen 3 microarchitecturehigher base and boost clock, 19% IPC improvements and, of course, a very high core and thread count, reaching 64 and 128 respectively.

the new line wire cutter The Pro 5000 WX offers five models for professional application, based on modified EPYC “Milan” data center chips. The “most basic” is the wire cutter Pro 5945WX, with 12 cores, 24 threads and 280 W TDP. About the frequencies, this CPU has both a slightly higher base and boost clock than the 3000 series predecessor “Castle Peak”, offering clocks up to 4.5 GHz.

The high-end processor of the new Threadripper, the 5995WX Pro, it has 64 cores and 128 halo threads, a base frequency of 2.70 GHz and eight 8-core CCDs (Main Chiplet Arrays). AMD also added a 24-core, 48-thread 5965WX model not present in the previous generation, with a base clock of 3.80 GHz and four CCDs, each with 6 cores enabled.

The Threadripper Pro 5000 WX series bridges the gap between Ryzen desktop and EPYC 7003 server processors, offering powerful configurations like EPYC but on a chip/platform better suited for workstation use.

Overall, the five new processors clocked up to 4.5GHz dual-core, which is a generational jump from 200MHz to 300MHz, depending on the previous model we’re comparing. The average base clock improvement is 100 MHz, except for the Threadripper Pro 5995WX.

AMD managed to squeeze more frequency and IPC improvements from the same 280W TDP as the last-gen Threadripper, but claims to have worked on power management, offering lower power cost per core 67% lower than the competition. Coming from the next generation Threadripper Pro 3000 platform, the most significant change in the 5000 Pro series is that its cores are now based on the Zen 3 architecture, replacing the older Zen 2 cores used in the TR Pro 3000 d ‘origin. In addition to the EPYC processors from which these parts are derived, AMD uses a combination of Zen 3 (CCD) chips built on TSMC’s 7nm process, along with their familiar I/O die which is built on TSMC’s 12nm process. Global Foundries.

From generation to generation, AMD has not increased the number of processor cores. What has changed is the increase in IPC over the “Zen 3” architecture, improvements in multi-threaded performance, and increased clock speeds.

The new Threadripper Pro hits 256MB of L3 cache on the higher-end models, but the performance boost comes from their structuring, which is now a contiguous 32MB block for each eight-core cluster. Other highlights include 128 PCIe 4.0 lanes and eight channels of DDR4-3200 ECC memory.

Interestingly, the grip of the new Threadrippers has not yet been mentioned in the official specs. According to available information, AMD has used the AMD sWRX80 socket and works with the WRX80 chipset, bringing compatibility with previous generation systems and motherboards via a BIOS update. Other sources like Anadtech and Wccftech treat the socket as an LGA 4094 or 4096.

The new chips also pack all the same Pro features as their predecessors, such as the Pro Security packages, which include the same AMD Secure Architecture, Memory Guard and Secure Processor Manageability and Business Ready packages. As a novelty we have the Shadow Stack, a mechanism to counter the flow of control attacks.

As far as we know, the Threadripper Pro 5000 chips will hit the market first in an updated line of workstations. Lenovo ThinkStation P620 – there will be a period of exclusivity for the company. This is exactly how AMD launched the previous generation of Threadripper PRO chips. AMD plans to announce more OEM/SI partners in the second half of 2022. There is no confirmation that these professional processors will arrive at retail and we do not have official published prices.

And as for the non-Pro models of the Threadripper 5000, there is still no certainty that they will make it to the super computing (HEDT) market. However, the possibility still exists, as Intel is reportedly preparing its Sapphire Rapids HEDT line, with up to 56 cores and DDR5 and PCIe 5.0 support, for this market.
