AMD announced the consolidation of its current trio of desktop APU/CPU sockets into a unified AM4 socket all the way back in January at the Consumer Electronics Show. At the time, AMD disclosed that future "Summit Ridge" and "Bristol Ridge" chips would arrive to fill this socket, but did not offer any additional information.
In the intervening months, AMD has clarified that Summit Ridge represents the upcoming 14-nm Zen architecture-based processors and Bristol Ridge refers to seventh-generation APUs based on the Excavator CPU core and GCN 3.0 graphics architecture.
PC enthusiasts waiting for Zen have a bit longer to wait, but reddit user starlightmica posted that those wishing to explore the performance of AMD APUs in conjunction with DDR4 memory can head to Costco and pick up the evocatively-named HP 510-P127C Pavilion desktop computer based on the HP "Willow" motherboard.
The HP Willow microATX motherboard is built around AMD's Promontory Fusion Controller Hub, bringing with it support for PCIe 3.0 and DDR4 memory. HP's motherboard support page details support for Bristol Ridge A8-9600, A10-9700, and A12-9800 APUs, all of which are quad-core 28-nm chips with 65W TDP. Some future Summit Ridge CPUs have TDPs up to 95W, though this board appears to be limited to 65W units.
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.
The specific PC available at Costco includes a 1TB magnetic hard disk, 16GB of DDR4 memory at an unspecified clock speed, a top-of-the-line A12-9800 APU, an 802.11ac Wi-Fi adapter, and a DVD recorder for just under $600.
