AMD 3rd Gen Threadripper TRX4, WRX8 Leak Hints At 8-Channel Memory, 128 PCIe 4 Lanes

Asus threadripper socket
Back in late August, we got our first glimpse at the chipsets that will underpin AMD's new third-generation Ryzen Threadripper processors, which are based on Zen 2 architecture. At the time, we didn't know anything about the chipsets other their names which were TRX40, TRX80, and WRX80.

We later got word of two upcoming motherboards from ASUS and MSI: the Prime TRX40-Pro and the ROG Strix TRX40-E Gaming, and the TRX40 PRO 10G and TRX40 PRO WIFI respectively. Today, we're learning a little bit more about the Ryzen Threadripper 3000 processors, which will allegedly be split into TRX4 HEDT and WRX8 configurations according to Gamers Nexus. From the looks of things, TRX4 and WRX8 are synonymous with X and WX designations with the current Ryzen Threadripper 2000 family.

The TRX4 HEDT platform is the lesser of the two, and supports up to quad-channel memory (DDR4-3200). Two DIMMs per channel are supported, with a maximum of 256GB total capacity per channel. Up to 512KB of L2 cache is available per core along with an undetermined (at this time) amount of L3 cache. There will be a total of 64 PCIe 4.0 lanes supports, with 16 configurable for SATA devices.

As for the WRX8 processors, we're looking at 8-channel DDR4-3200 support, with one DIMM per channel (maximum 256GB/channel). These processors will also allegedly have 512KB of L2 cache per core along with as many as 128 PCIe 4.0 lanes, with 32 of those lanes switchable for SATA.

One other interesting tidbit is that the TRX4 HEDT processors will support overclocking, while the more workstation WRX8 processors will have that functionality disabled.

AMD Threadripper Geekbench

At this point, we've seen several benchmarks for an alleged "Sharkstooth" Ryzen 3000 processor with 32 core and 64 threads. In the Geekbench listing above, this particular prototype chip features a base clock of 2.2GHz and a boost frequency of 4.17GHz. Although we've seen score fluctuate wildly for Sharkstooth, this example put up rather impressive single-core and multi-core scores of 5523 and 68576 respectively compared to the current flagship Ryzen Threadripper 2990WX at 4776 and 36042 respectively.

AMD third-generation Ryzen Threadripper family is tipped to arrive later this year according to reports.
