I'd agree....
IN Autocad 2004 Ht will only help on rendering and pan and zoom regeneration. IN Architectural desktop 2004 with multithreaded enabled rendering in animation sets is 19-22% faster with HT on and enabled.
IMO...AMDs when compared PR rating to INtel processor speed are faster. However HT enabled chips then take back over the lead versus like speed chips....
What I can tell is my p4 2.4@3.5ghz was fast, but now my A64 3000+ at 2600mhz which could be equivalent to a 4000+ actually regains the lead. I need to rerun the test to see if the added bandwidth (which Autocad does like more so then other applications) gives me even a more added boost.
HT is Intel's saving grace an leveler to the workstation playing field....
I think if you go dual, dual xeons would only be a better option for me cause I could potentially get 2 (sub 200) 2.4ghz chips and OC them to levels of 3.3-3.6ghz and then with HT enabled on both would be the fastest at autcad Rendering (remember only rendering here I am talking about). Opterons seem to be almost Ocing impossible ao it would take 2 very expensive opterons to equal it...
NOw if we are thinking single desktop chips I would give the advantage to the AMDs which have better bandwidth., appear to have better IDE performence, and get potentially get to speeds to negate HT in chips maybe as far as 3.8ghz with a fraction of the cost...
