IBM's Power A2 is a 16 core chip. It's actually pretty small and low wattage.

It's not a beast of a CPU like you'd think given the number of cores.

It could be the A2 but it makes no sense. The problem with so many cores is the programming. And you cant infinetly parallelize every task. So 16 weak cores are actually suckier to programm then 4 strong ones. And have no benefits I can think of.

 

If MS really wants 16 cores its possible that its going to be strong cores because if its weak ones they would be better of with 4 Core CPUs

 

But I think its an 8 core Power 7 with HT if the rumor is true. That would be like 16 current 360 cores with 2 Threads each.

Power7 and Core A2 are both 4 way multithreaded.   So the 8 core Power7 would have 32 threads and the 16 core Power A2 would have 64 threads.

I only mentioned Power A2 because it is already a 16 core CPU.  No other usable 16 core CPU's exist or are in immediate development in time for use.

If they are calculating core count by adding the number of actual cores and logic cores (threads) then it core either be an 8 core AMD CPU (2 threads per core) or a 4 core IBM CPU (4 threads per core).
