Nearly exactly one year ago, Qualcomm announced the Snapdragon 8cx processor for always-on always-connected PCs, and lateron Qualcomm and UL released PCMark 10 benchmark results showing Snapdragon 8cx had similar performance to a 15W Intel Core i5-8250U Kaby Lake-R processor, but with much better efficiency.
The price of such laptops is still fairly high with Samsung Galaxy Book S announced in August for $1,000, and possibly canceled at this stage. Microsoft SQ1 powered Surface Pro X tablet is the only system based on Qualcomm Arm technology (customized version of Snapdragon 8cx) available now, and also sells for $1,000
