The SnapDragon 8xx SOC in comprised of several different subsystem ( don't know if I can post the link to the Soc here, but its on Qualcomm's website ), so exactly what chipset are your looking for ? The question is too general for a concrete answer.
We are looking to develop a phone but we want advice on what chipsets
everyone seems to enjoy nowadays and see if we can take it or the step up
during our process. We want power.
