Two ASUS TRX40 chipset based motherboards for the 3rd gen AMD Ryzen Threadripper processors have been listed by multiple retail stores. The motherboards which are designed for the new HEDT lineup would be launching soon so it's expected to see them listed on retail outlets prior to launch but what's interesting is that the same retailers have also mentioned prices for the new products.
ASUS TRX40 Motherboards For 3rd Gen AMD Ryzen Threadripper HEDT CPUs Listed - Huge Price Increase Over X399 or Just Placeholders?
The two motherboards that have been listed include the ASUS ROG Zenith II Extreme and the ASUS PRIME TRX40-Pro. Both of these motherboards have been listed along with their prices which are a huge increase over their predecessors. The ROG Zenith II Extreme, for instance, has a listed price of $1343.52 (AUD) which is roughly around $900 US. The PRIME TRX40-Pro has been listed for $833 (AUD) or roughly $500 US.

Considering that the ROG Zenith Extreme Alpha based on the X399 chipset can be currently found for $599.99 US and the PRIME X399-A can be found for $299.99 US, this seems like a major price bump. Now there are two things, we have seen that the X570 motherboards cost more than their X470 and X370 predecessors. The design choices and feature set, along with advanced cooling methodologies definitely add to the overall cost. The TRX40 series, however, has around a 2x price increase compared to their X399 predecessors.

It is highly likely that the TRX40 motherboards would cost more than their X399 predecessors of the same segment but not as much as the pre-listed prices. Just like every early listing, these are, more or less, placeholders till the real prices are confirmed. There are people who will pre-order motherboards on these prices since availability at launch is a major issue nowadays but I would personally advise such buyers to wait until the products are officially announced along with their respective MSRP's and not placeholders.
AMD Ryzen Threadripper 3000 Series CPUs - Here's What To Expect In Terms of Price, Specs, and Performance
The AMD Ryzen Threadripper 3000 series family is internally known as “Castle Peak” and is stated to bring dominant leadership in the HEDT market. The family will prove to be a new watermark in performance and overall efficiency while new platform features will be introduced on the new and enhanced TR4+ motherboards which are rumored to feature a revised socket and a new chipset

Currently, reports state that there will be two separate platforms for enthusiasts and workstation chips, the TRX40 and WRX80. The details of these platforms are listed below.
AMD TRX40 'Enthusiast' Ryzen Threadripper 3000 Processors
The TRX4 HEDT platform would feature quad-channel memory, UDIMM memory support with 2 DIMMs per channel and up to 256 GB of capacity per channel. This means that the platform will support up to 1 TB of memory. There would also be support for 64 Gen 4 PCIe lanes with 16 lanes switchable with the SATA interface. There also seems to be info regarding TDPs and we can also notice the segmentation here too. The Group 'A' series processors, which are the HEDT lineup for the TRX40 platform with 280W TDP, Tcase Max temperature of 60C and Tctl Max of 100C.
AMD WRX80 'Workstation' Ryzen Threadripper 3000 Processors
Now coming to the WRX80 series, we are looking at a pure workstation lineup. Even the processors built around this platform are spec'd similar to the EPYC 7002 variants, featuring 8-channel DDR4-3200 support in UDIMM, RDIMM, LRDIMM flavors. The platform would support 1 DIMM/channel featuring support for up to 2 TB of memory. There wouldn't be any OC support like the TRX40 series but you get 96-128 Gen4 PCIe lanes with 32 switchable lanes to SATA. The Group 'B' series processors which are the workstation lineup for the WRX80 platform will also feature a 280W TDP but different temperature range of Tcase Max temperature of 81C and Tctl Max of 100C.
