AMD has reportedly completed documentation of its future Stoney Ridge platform. While Bristol Ridge is a mainstream APU coming in Q3 2016, Stoney Ridge focuses on the lower-end and is expected to be released in the same timeframe.
WCCF Tech claims Stoney Ridge will be the last version from the Bulldozer family, the site notes the chip will have two Excavator cores and heard it looks a bit like a Carrizo cut in half.
It looks like AMD has one more processor up its sleeve that will feature the Bulldozer family. The Stoney Ridge APU will feature 2 x86 Excavator cores and 3 GCN cores for a grand total of 5CUs. Comparatively, the main APUs usually have a combination of 4 x86 cores and 8 GCN cores. This APU will be socketed on the AM4, FP4 and FT4 packages – so it will make an appearance on the mobility side as well. The TDP of the APU is not known at the moment although rumors put the power draw of the mobility chip at around 14W. These APUs are targeted at the casual HTPC build will probably feature the single DDR4 IMC controller. This is completely fine since by 2016 or so, DDR4 memory prices will be cheaper than DDR3.
Details about why AMD is preparing this chip are a bit murky. It could be AMD is increasing its focus on lower-power APUs or HTPC systems or perhaps the firm may use this chip to test run the 14nm process at low clocks.
