AMD Ryzen Threadripper 9000: High-end CPUs for workstations and desktop PCs
AMD has updated its Threadripper processors to the Zen 5 architecture. There is a choice of workstation CPUs with 96 cores and desktop chips with 64 cores.

At the Computex IT trade fair in Taiwan, AMD presented the Ryzen Threadripper 9000 series of workstation processors, also known as Shimada Peak. Following the Ryzen 9000 desktop CPUs, the Ryzen AI 300 mobile chips and the Epyc 9005 server processors, this is the last CPU series to be equipped with the latest Zen 5 cores. The Threadripper 9000s come with up to 96 cores and are technically closely related to the Epyc 9005. They are particularly suitable for rendering, AI and scientific calculations.
The Zen 5 architecture calculates around 16 percent faster per clock cycle than Zen 4. AMD achieves this through a decoder in the front end that is twice as wide, data paths that are now 512 bits wide across the board, from which floating-point calculations in particular benefit, and faster connected caches. In addition, the memory clock of the ECC RAM has been increased from DDR5-5200 to DDR5-6400.
Ryzen Threadripper Pro 9000WX for workstations
As with its predecessor, the Threadripper 7000, the Shimada peak processors are divided into two series. The larger and more important group of workstation CPUs Ryzen Threadripper Pro 9000 WX, with six CPUs, have 12 to 96 cores, 128 PCIe 5.0 lanes and eight memory channels. They run in existing WRX90 mainboards after a BIOS update and retain the maximum power consumption of 350 watts. This, as well as the maximum clock speed of 5.4 GHz, applies to all types, regardless of whether the Threadripper Pro 9000WX CPU has 12 or 96 cores.

According to AMD, the top model Ryzen Threadripper Pro 9995WX with 192 threads should set a record in the Cinebench rendering benchmark. The processor should achieve 2.2 times the score of the Intel Xeon w9-3595X (Sapphire Rapids) with 60 cores and 120 threads. According to AMD, the 96-core processor is 40 to 145 percent ahead of the Intel competition in professional applications.

Ryzen Threadripper 9000X for desktop PCs
The second group is the more affordable high-end desktop (HEDT) Threadripper 9000X variants with 24, 32 and 64 Zen 5 cores. However, the three CPUs can only control four memory channels and 64 PCIe 5.0 lanes. They also lack the remote maintenance functions of the Threadripper Pro 9000WX. The HEDT processors fit into existing TRX50 mainboards of the Ryzen Threadripper 7000X. The power budget and maximum clock rate are identical to those of the workstation variants. All nine Ryzen Threadripper 9000 processors presented are due to go on sale in July.
