Tech tipster momomo_us yesterday spotted that ASRock Rack had listed a new and interesting looking motherboard on its product website, albeit in a "preliminary" category—so pricing and availability have "to be determined" status currently. The W790D8UD-1L1N2T/BCM is a new addition to the company's selection of compact workstation boards, but it distinguishes itself by being the first example of a W790 chipset Deep Micro ATX mainboard with platform support for Intel's latest "Sapphire Rapids" Xeon W-2400 and W-3400 processors. The single E-type socket (LGA 4677) looks absolutely huge relative to the overall dimensions of its surroundings (264 × 266 mm). The Deep Micro ATX form factor is exclusive to AsRock Rack so it could be tricky to build with a W790D8UD-1L1N2T/BCM board, given that mainstream PC cases may not provide full compatibility with this proprietary configuration.
ASRock Rack W790D8UD-1L1N2T/BCM is capable of running up to 56 cores (the minimum being 6) and 2 TB of DDR5-4800 modules (eight DIMM slots) with a peak bandwidth of 307.2 GB/s, via the platform's advanced memory subsystem. Sapphire Rapids Xeon W processors can control up to 112 PCIe Gen 5 lanes (W-3400) and 64 PCIe Gen 5 lanes (W-2400). Tom's Hardware has kindly collated the rest of the specifications into sentence form: "As for the physical connectivity, the motherboard is equipped with four PCIe x16 slots, one M.2-2280 slot with a PCIe 4.0 x4 interface attached to the W790 PCH, and two OCuLink connectors for SSDs. Network connectivity includes two 10GbE ports controlled by Broadcom BCM57416, a GbE connector managed by the Intel I226, and another GbE handled by the Intel I210. In addition, it has a dedicated GbE port for remote management with the support of Aspeed AST2600 BMC, that is handled by the Realtek RTL8211F. The board also has an SPI connector for TPM modules, USB 3.2 Gen 1 ports, a COM port, and a D-Sub VGA display connector."
