Last 12 months we noticed that AMD was out there to rent a brand new lead product supervisor for a ‘workstation division’. This was a categorically totally different place to the lead PM for high-end desktop, and so we speculated what this truly means. Today, AMD is saying its first set of workstation merchandise, underneath the Ryzen Threadripper Pro branding. However, it must be famous that these processors will solely be obtainable as a part of pre-built methods, and no corresponding shopper motherboards will probably be made obtainable.
Taking Threadripper To Pro
The product stack from AMD has included Ryzen Pro and Ryzen Mobile Pro {hardware} for a few generations – these processors supply ECC-enabled variants together with company assist on safety, manageability, and working system picture consistency. Most of us had assumed that whereas Ryzen had a Ryzen Pro variant, essentially the most pure variant to Threadripper was AMD’s EPYC processor line of server processors. The server market and the high-end-desktop/workstation market have all the time type of overlapped, and up so far if a consumer was taken with a workstation-like design, with ECC and software program validation, they’d look to EPYC.
Today AMD is altering that dynamic with Ryzen Threadripper Pro.
Ryzen Threadripper Pro {hardware} will mirror single-socket EPYC in its options: eight reminiscence channels as much as DDR4-3200, 128 lanes of PCIe 4.0, assist for RDIMMs and LRDIMMs, assist for safe reminiscence encryption, assist for DASH manageability, and working system picture consistency as a part of AMD’s Pro Business Ready programme.
Where Ryzen Threadripper Pro differs is within the core rely/frequency/TDP configurations.
| AMD Ryzen Threadripper Pro | ||||||
| AnandTech | Cores | Base Freq |
Turbo Freq |
Chiplets | TDP | DRAM |
| 3995WX | 64 / 128 | 2700 | 4200 | 8 + 1 | 280 W | Eight x DDR4-3200 |
| 3975WX | 32 / 64 | 3500 | 4200 | 4 + 1 | 280 W | Eight x DDR4-3200 |
| 3955WX | 16 / 32 | 3900 | 4300 | 2 + 1 | 280 W | Eight x DDR4-3200 |
| 3945WX | 12 / 24 | 4000 | 4300 | 2 + 1 | 280 W | Eight x DDR4-3200 |
There can be a small distinction in DRAM assist – TR Pro helps as much as 2 TB, however EPYC helps Four TB. All of the Ryzen Threadripper Pro processors are single socket solely.
The high processor, the 3995WX, will supply all 64-cores. It goes above and past the standard high EPYC 7742 (225 W, 2.25 GHz / 3.Four GHz) and even the 7H12 (280 W, 2.6 GHz / 3.Three GHz), by providing extra base frequency at 2.7 GHz and a a lot larger turbo frequency at 4.2 GHz for 280W TDP. These processors may be profiting from the identical manufacturing replace as supplied by the latest Ryzen 3000XT processors to be able to drive these larger frequencies.
AMD says that its core rely and frequency configurations are designed to swimsuit a wide range of totally different licensing fashions, for software program that has licenses per core (the place the excessive frequency fashions are really helpful) or per socket (the place extra cores are really helpful).
OEM Only
One of the attention-grabbing parts of TR Pro is that it’s set to be an OEM solely product. This implies that events should discuss to Lenovo or others to be able to receive the {hardware}. As it stands, Lenovo is ready to be the launch companion for the TR Pro household, the place it is going to be provided as a part of its ThinkStation P620 household. Lenovo will supply its P620 in all totally different flavors, with as much as 1 TB of DRAM and twin RTX 8000 GPUs (or 4 RTX 4000 GPUs).
Lenovo’s P620 use the socket in a rotated orientation to assist with airflow, however this additionally limits the socket to just one DIMM per channel, therefore why we’ve the 1 TB max reminiscence assist. The system will use numerous Lenovo’s ThinkStation improvements, equivalent to detachable followers and drives and such.
