Threadripper Pro support 2 TB of RAM

The Threadripper Pro CPUs with up to 64 cores and eight memory channels are in Lenovo’s Thinkstation P620.

AMD introduced the Threadripper Pro: The processors intended for workstations have up to 64 cores and, unlike the regular Threadripper models like the 3990X (test), eight instead of four memory channels. The CPUs will initially be used exclusively by Lenovo, more precisely in the system called the Thinkstation P620.

The Threadripper Pro are designed for the sWRX8 socket instead of the sTRX4, which is why they support eight instead of four memory channels. In order to differentiate the CPUs from the regular thread rippers and from the 1-socket versions of the Epyc 7002, a maximum of 2 TB instead of 512 GB or 4 TB working memory is supported. In addition, there is the WRX80 chip with I / O functions, which is not available in the server segment. The 128 PCIe Gen4 lanes are identical to those of the Epyc 7002, the Threadripper has 64 lanes.

The top model is the Threadripper Pro 3995WX with 64 cores, AMD also offers the Threadripper Pro 3975WX (32C), the Threadripper Pro 3955WX (16C) and the Threadripper Pro 3945WX (12C). Compared to the 1-socket chips of the Epyc 7002, the thermal power loss is 280 watts instead of 200 watts, which means higher frequencies are possible: while the Epyc 7702P reaches 2 GHz to 3.35 GHz, the Threadripper Pro 3995WX is the same 2.7 GHz to 4.2 GHz. According to AMD, its own 64-chip is faster than two Xeon Platinum 8280 (28C) from Intel.

Lenovo installs the Threadripper Pro in the Thinkstation P620, which measures 460 x 440 x 165 mm and is air-cooled. In addition to up to 1 TB of RAM, the Chinese offer up to 20 TB of storage space through two M.2 NVMe SSDs and four hard drives. To support the CPU, up to two Quadro RTX 8000 or up to four Quadro RTX 4000 can be installed. The system is delivered with Wi-Fi 5 (802.11ac) and 10 Gigabit Ethernet. Lenovo plans to sell the Thinkstation P620 from October 2020, prices are not yet available.
