The picture shows yet undisclosed AMD HEDT motherboard. The branding does seem to indicate that we are looking at a premium AORUS motherboard. The socket, which looks identical to Threadripper 2000’s TR4, is likely to be the new TR4+ or TR+ socket. The discussion on backward compatibility has not yet materialized in any substantial proof that it might work. Hence, we cannot be sure if TR2000 chips will work on TRX40 motherboards and if TR3000 CPUs will work on X399.
The AORUS TRX40 motherboard is clearly an E-ATX standard (same as X399 AORUS Xtreme) while the previous GBT X399 motherboards kept a standard ATX form factor. This board features four PCIe x16 slots (4.0) and eight DDR4 slots for quad-channel memory. We can also see a fan over the chipset and debug LED.
Large fin arrays can be spotted around the CPU socket, this is likely an indicator of very high wattage of the Threadripper 3000 series (rumored to go up to 280W). We recently revealed that AMD is planning to announce the new TR series on November 5th. New motherboards are also expected to be showcased at the same time.
Based on confidential documents that we have, in November AMD will announce a Threadripper 3990X CPU, which might be a 64-core CPU (unconfirmed). This motherboard would definitely support it.
