The first W790 motherboard exposed.
More detailed photographs of SuperMicro’s W790 motherboard have just surfaced online. This is a follow-up to our story from last month, where we had shared a low-resolution photograph of the same motherboard. It looks like these next-gen Xeon/HEDT platforms are now shipping to distributors/retailers.
The SuperMicro X13SWA-TF is the next gen motherboard for LGA4677 processors codenamed Sapphire Rapids. Intel has not disclosed its plans for the Xeon Workstation/HEDT systems yet (apart from saying that they are close); however, a very extensive leak had place recently revealing two product series: Xeon W-3400 (112L) and Xeon W-2400 (64L). SuperMicro’s motherboard is compatible with the higher-end series which have a base power up to 350W.
The spec sheet that leaked alongside these photographs, confirm that X13SWA-TF will support up to 56 core from Intel Sapphire Rapids series. Up to 2TB of memory will also be supported as long as RDIMM 3DS memory is used. However, the board also supports up to 4800 MT/s transfer speed with all 8 memory channels occupied by one DIMM.
Although there are not many PCIe Gen5 products available yet, this motherboard has 6 x16 slots just in case they are needed. Here, SuperMicro is clarifying that Xeon W-2400 (64L) series will only support 3 slots at full speed.
The X13SWA-TF is an E-ATX form factor motherboard powered by 24-pin and three 8-pin power connectors. It has a built-in audio chipset, USB and SATA connectors, so technically nothing prevents one from using it for a very high-end workstation system that could still play games.
