[hpsdr] Whitch CPU will be better for HPSDR?

[ad0es]

Hi All,

I am currently writing code for what I call ngHermes, a (set) of 
programs that run on a "thick pipe SDR" that
runs the next generation DFC hardware.  I chose:

     Asus X99-E WS Motherboard
     MSI GTX980 (ngSDR CUDA)
     CPU: Intel i7-5960X, 8 hyperthreaded cores for 16 virtual cores
     32GB Memory: Corsair DDR4 (8GBx4)
     Power Supply: Corsair 1500

Base ngHermes uses about 9-10 threads currently, but will use dozens 
when supporting a large number of receivers.
This is all running on an Ubuntu system, which allows me to assign 
specific cores to specific threads, as well as run
threads at specific priorities.  I expect to be able to keep all 16 
cores (and then some) busy!

Note that the GTX980 is used to do the heavy math traditionally done by 
the FPGA on the hardware of earlier
generation SDRs.
