The launch of Bristol Ridge was pretty small, so far we haven't seen any standalone parts yet, but some computers have made their way to the retail channel. The Tech Report writes Costco is selling the HP 510-P127C Pavilion desktop computer for $599.99.
Pictured below, this system features the HP Willow microATX motherboard with the AMD Promontory Fusion Controller Hub. The HP 510-P127C features the A12-9800 APU (the highest-end model), AMD Radeo R7 graphics, a 1TB HDD, 16GB DDR4, 802.11ac WiFi, and a DVD burner.
It's an OEM motherboard so there's not a lot to get excited about as it has a bare minimum of features:
The board offers a single PCIe x16 slot and and A-keyed M.2 slot, which seems to imply support for PCIe x2 SSDs. DDR4 memory as fast as 2133 MT/s is supported in configurations up to 16GB spread across two slots. The Willow motherboard is suspiciously lacking USB 3.1 ports, Type-C or otherwise. Whether this is related to mid-summer rumors that AMD and Asmedia were dealing with signal integrity issues with USB 3.1-related circuitry remains unknown.
