AMD introduced the Zen 3 Threadripper professional processor

AMD today released its first Ryzen Threadripper processors based on the Zen 3 microarchitecture, the Ryzen Threadripper PRO 5000WX series. Designed for direct compatibility with AMD WRX80 chipset-based workstations and motherboards, these processors are available with up to 64 cores/128 threads and offer huge I/O capabilities, including 8-channel DDR4 memory with ECC support and a 128-line PCI-Express 4.0 root set.


The biggest change from the previous generation Threadripper PRO 3000WX series has to be the use of "Zen 3" CCDs, each with 8 CPU cores sharing a common 32MB L3 cache. AMD does not use Zen 3 chipsets with 3DV Cache.


A full set of AMD PRO management features from Ryzen PRO are available on these CPUs, including PRO Security, PRO Management and a dedicated support channel that includes scheduled parts and software availability. What's more, AMD has partnered with independent software vendors to create most professional content creation software since the last generation Ryzen Threadripper PRO to optimize their software for the processors. Their benefits are available to all generations of Threadrippers. Although all components in the Threadripper PRO 5000WX series are rated at 280W TDP, AMD claims to have worked on power management, offering up to 67% lower power per core compared to competitors (2P Xeon Scalable Platinum 8280).


The latest version of AMD PRO Security borrows the Ryzen 5000 PRO and EPYC "Milan" feature sets and is basically an AMD Shadow Stack. AMD describes it as "a security feature designed to eliminate threat vectors such as return-oriented programming attacks. It helps keep track of return addresses so that comparisons can be made to ensure that integrity is not compromised. In addition, AMD Shadow Stack allows you to use Microsoft hardware. You also get AMD Secure Memory (hardware-accelerated memory encryption) and a hardware dynamic root of trust.


The Ryzen Threadripper PRO 5000WX series includes five models. The series starts with the 12-core/24-threaded Threadripper PRO 5945WX (two CCDs, each with 6 active cores). The processor runs at 4.10GHz. The Threadripper PRO 5955WX is a 16-core/32-thread processor clocked at 4.00GHz with two CCDs, each with all eight cores active. The Threadripper PRO 5965WX is a 24-core/48-thread processor with a base frequency of 3.80 GHz and four CCDs, each with six active cores. The Threadripper PRO 5975WX is a 32-core/64-threaded unit with a base frequency of 3.60 GHz and consists of four CCDs with all the cores involved. As with the 3000WX series, AMD skipped the 48-core/96 thread part and went straight to the 5995WX with a maximum of cores/128 threads and a base frequency of 2.70GHz with eight 8-core CCDs.
