For CPU performance comparison look at:<br><br><a href="http://www.spec.org/cpu2006/results" target="_blank">www.spec.org/cpu2006/results</a><br><br>for
each CPU look at the statistics for floating point operations, namely
for SPECfp_base2006 score for the programs of interest (GAMESS, GROMACS,
NAMD, etc.).<br>
<br>For graphics cards you can look at the same site for GPU availability and memory...<br><br>HTH,<br>Thomas<br><br><br><div class="gmail_quote">On 2 May 2012 12:51, melichercik <span dir="ltr"><<a href="mailto:melichercik@nh.cas.cz" target="_blank">melichercik@nh.cas.cz</a>></span> wrote:<br>

we plan to buy some computer mostly for gromacs, so I want to ask you for some hints. I'd tried to do some research, but no success. :(<br>
<br>
Have someone ever compared AMD Bulldozer and Sandy/Ivy Bridge architectures? Are there planed any optimizations in gmx core in asm parts? (if there are need).<br>
Most interesting for me whould be to compare FX-8150 and i5-2550, I7-2600, i7-3570K or i7-3770 processors.<br>
<br>
GPGPU - are there some real plans for supporting Radeon GPUs? Because OpenMP 3.x supports them - but I don't have any idea how complicate is to use newer OpenMP in GMX (and another work about it).<br>
<br>
And are there bigger differences (if someone knows) in use 1 Gbps onboard NIC vs. "better"? add-on NIC cards e.g. Intel Pro/1000 CT or similar? In MPI calculations with use 4 to 8 cores per computing node.<br>
<br>
<br>
Thanks a lot.<br>
