GIGABYTE Threadripper TRX40 AORUS Motherboard Teased

AMD is going to launch its premium HEDT Threadripper CPUs, based on 7 nm manufacturing process, as soon as November 5th arrives. To prepare for the launch, manufacturers like GIGABYTE have been working hard to bring new CPUs to life, by integrating AMD's new chipsets into the new motherboard models. Dubbed "Castle Peak" and "Sharkstooth", the two new CPU variants will be accompanied by TRX40, TRX80 and WRX80 chipsets, each enabling additional features.

We now got a hold of the first picture of what appears to be GIGABYTE's AORUS motherboard based on TRX40 chipset. Coming in with the E-ATX form factor, this motherboard is similar in size with the previous X399 AORUS Xtreme model. It features four PCIe 4.0 x16 slots and eight slots that support four-channel DDR4 memory, so it is likely that TRX40 chipset is meant only for such configuration, with TRX80 and WRX80 chipsets being reserved for eight-channel memory configurations. Another thing to note is the presence of chipset fan, indicating that the TDP of these chipsets is high and it needs to be actively cooled in normal use cases. If you remember, plenty of X570 boards have a fan on chipset as well due to their TDP.

AMD Readies Three HEDT Chipsets: TRX40, TRX80, and WRX80

AMD is preparing to surprise Intel with its 3rd generation Ryzen Threadripper processors derived from the "Rome" MCM (codenamed "Castle Peak" for the client-platform), that features up to 64 CPU cores, a monolithic 8-channel DDR4 memory interface, and 128 PCIe gen 4.0 lanes. For the HEDT platform, AMD could reconfigure the I/O controller die for two distinct sub-platforms within HEDT - one targeting gamers/enthusiasts, and another targeting the demographic that buys Xeon W processors, including the W-3175X. The gamer/enthusiast-targeted processor line could feature a monolithic 4-channel DDR4 memory interface, and 64 PCI-Express gen 4.0 lanes from the processor socket, and additional lanes from the chipset; while the workstation-targeted processor line could essentially be EPYCs, with a wider memory bus width and more platform PCIe lanes; while retaining drop-in backwards-compatibility with AMD X399 (at the cost of physically narrower memory and PCIe I/O).

To support this diverse line of processors, AMD is coming up with not one, but three new chipsets: TRX40, TRX80, and WRX80. The TRX40 could have a lighter I/O feature-set (similar to the X570), and probably 4-channel memory on the motherboards. The TRX80 and WRX80 could leverage the full I/O of the "Rome" MCM, with 8-channel memory and more than 64 PCIe lanes. We're not sure what differentiates the TRX80 and WRX80, but we believe motherboards based on the latter will resemble proper workstation boards in form-factors such as SSI, and be made by enterprise motherboard manufacturers such as TYAN. The chipsets made their way to the USB-IF for certification, and were sniffed out by momomo_us. ASUS is ready with its first motherboards based on the TRX40, the Prime TRX40-Pro, and the ROG Strix TRX40-E Gaming.
