OnePlus One will have the Snapdragon 801 under the hood after all9
But something has changed. On the OnePlus Google+ page, the specs now show a Snapdragon 801 CPU. No one really criticized OnePlus for its earlier decision since the reasons they gave for going with the Snapdragon 800 were all "consumer-friendly." Hopefully the new specs don't indicate a change in pricing or availability. The difference between the two is that the Snapdragon 801 offers higher maximum CPU and GPU clock speed, support for Dual SIM, Dual Standby, and a faster LPDDR3 interface.
The rest of the specs listed on the Google+ page include a 5.5 inch 1080 x 1920 resolution screen, a 13MP camera featuring a Sony Exmor sensor (and an f/2.0 aperture), StyleSwap replaceable back covers, and a 3100mAh battery.
