Does HFSS operate better on Intel HT or AMD ?

HFSS On HT or AMD

I am wondering if HFSS operates better on AMD than Intel HT. I got a 3.2 HT machine, which still isn't that fast I expected with such power. I wonder if any knows why!!

the speed is only relate with your computer memory.

spead relate to RAM of your
computer and CPU , if your RAM rather than 512
and CPU rather than 1G ,analyse spead of HFSS
is suitable ,and only your problem , if you don't have
powerfull computer is that the time of analysise
is longer , and if your work don't have symmetry
the analyse take more time .

i have similar config but i use 1Gb of RAM which is dual channel 2 sticks of 512 mB ram on 3.2HT n it works just fine

What type of AMD's processor did you use for difference measurement?

I have done benchmarking using HFSS between Intel Pentium 4/EMT64 and AMD Opteron architectures...

Bottom Line - Single processor systems
Memory to processor speed has the primary impact on solve time

Bottom Line - Multi-processor systems
Memory to processor speed has the primary impact on solve time
Processor to Processor communication has a significant contribution to solve time


With the above achitectures, AMD is better than Intel with both memory to processor... and processor to processor communications

In a single processor system... An opteron running at 2.0 GHz was at least 15% faster than 3.0 GHz Intels

Going multiprocessors (1 to 2).. the Intel system was sped up by about 20 - 30%... where the AMD Opterons achieved about a 90%-95% increase.

If the problem goes out of memory... make sure that you also have a fast disk system... RAID 5 / SCSI 320 / and 15k spin drives seem to be pretty good.
