to use these tests isn’t a problem, but available workstation are too old,
so test results won’t be helpful in choosing actual components. I have an
access to high-performance cluster, but it also couldn’t be the basis
because of its high cost. If it is hard to give the certain recommendation,
I would to know at least how do performance correlate with the number of
cores/threads and core frequency? What is more important the core frequency
or number of cores? What is preferable, Intel or AMD? How should be
correlated GPU and CPU performance?
In the previous letters in mail-list I found recommendations on purchase of
Threadripper 1950X+GeForce GTX-1080Ti, I think that more cheap and similar
effective choice is TR 1950X+GeForce GTX-*1080*. Will there be significant
differences with 1)TR 19*20*X+GeForce GTX-1080 2) Intel 7900x+GeForce
