Early Design, please check above picture carefully
System Block = Cheap Low BW + EdRAM + Moderate GPU
Application Block = High SPeed BW + > Medium End GPU
People somehow always talking about the System Block
System Block as Early design = 48 ALU = 768SP = 1.2TF
System Block can be 2-4 Core, Low CPU clock
Application Block
Application Block = 32 x 2 = 64 ALu = 1024 SP = 2x (512 GPU) = 1.8 TF ~ 2.4TF
Application block = 8 Core CPU
*) App Block require split the GPU into Dual GPU setup to balance the L2
*) GPU running at hald the CPU clock, to balance that also related to L2, split the GPU into 2 GPU core per die
*)The base CLock is CPU/2 is rather high, so the GPU clocked 1.1GHz - 1.5Ghz, that's why the raw TF can 1.8 -2.4TF depend on CPU core Clock
*)The Rumored SPec what we got actually mixed up of App Block and System Block, The System Block dont have to be 8 core, it is the App Block that have to be 8 Core, so people mixed up 8 core from App block + GPU from System Block then the confusion spread, especially on neogaf.
RUmored Xbox next < PS4 it is true, because people keep talking the System Block
but as lately suggest there is special unit, it is actually there, if u look the patent, the app block it is the one done the heavy task, App block = Special Unit = Basic Troughput Engine, can be Anyhting for Heavy task, it is CPU-GPU combined, can not be said as standard GPU
so Xbox next rather weak if only sees as System Block 1.2TF.
real Xbox next = System + App Block > 3TF even at earlier design Based on old Leaked Yukon architecture
Xbox lite = just removing the APP block, then u got cheap XBox SOC, can be integrated even into TV set or other device
