Sapphire is back to its vocation of being a motherboard vendor, the popular ATI Radeon board partner designed a new socket AM3 motherboard based on the new AMD 890GX + SB850 chipset, dubbed the Sapphire Pure CrossfireX 890GX. The board is built on the ATX form-factor, though comes with only four expansion slots spaced out. The AM3 CPU is powered by a 10-phase VRM, it is wired to four DDR3 DIMM slots for dual-channel memory. The AMD 890GX northbridge is cooled by a large heatsink which shares its heat with one of the VRM heatsinks. The ATI Radeon HD 4290 IGP is assisted by 128 MB of SidePort memory apart from sharing the system memory.

Out of the four expansion slots, two are PCI-Express 2.0 x16 (electrical x8 when both are populated) with some sort of manual PCI-E lane switching, and one each of PCI-E x1 and PCI. The SB850 southbridge gives out six SATA 6 Gb/s internal ports, while an additional controller provides an IDE connector (for two IDE devices). The eSATA port is driven by manually connecting it with one of the internal ports. Connectivity includes 8 channel audio with optical and coaxial SPDIF, USB 3.0, and display connectivity, which includes DVI, D-Sub, and HDMI with 7.1 channel audio. Available soon, Sapphire is yet to disclose its price.
