Qualcomm, the company who makes the Snapdragon processor seen in many Android devices, has overhauled their naming scheme. Qualcomm’s naming scheme used to be MSM8260, MSM855T, MSM8930, and so on. Today, Qualcomm is moving their naming scheme into a four tier system: S1, S2, S3, S4.
S1 processors will be 1GHz and below and will be for mass market. S2 is for high performance devices, like the Droid Incredible, with speeds up to 1.4 GHz. Devices like the EVO 3 will fall under S3, with up to 1.5 GHz. And finally, S4 will be for everything between 1.6 GHz and 2.5 GHz — which doesn’t actually include anything, yet.
When better processors come around S1 won’t become S2, rather, a S5 tier will be created. Check out the S3 below: (via TechCrunch)
