What is your bottleneck?
Amount of DRAM?
Available bandwidth to DRAM?
L1, L2 or L3 cache?
I/O?
Floating point performance?
Integer performance?
Hard-to-predict branchy logic code?

Depending on what the problem is you're trying to solve, different
architectures and ways of slicing the work will perform differently.



Sincerely,

Jon Watte
