Sales -> If the mouth is moving they are lying.
Marketing -> Will lie when convenient or to get the customer interested, but will use the truth if it suits them.
Engineering -> Will tell the hard truth unless someone in sales beat them to it with a lie.
Sales -> The x8 is an eight CPU chip.
Marketing -> It has eight processors on board. Four are GPU, 2 Arm cores are for apps and the other 2 are for context specific computting.
Engineering -> It's a dual CPU architechture with an Adreno GPU that has 4 processors in the GPU, there are also a couple of embedded units used for language processing, status and house keeping. You only have 2 real cores for computing. It's really a 3 CPU chip because the GPU, even though it has four units all work in tandem. The other processing units make the experience better but you can't count the processing power.
