So that puts a dual to the equivalent (chess >equivalent) of 750 mhz, comparing identical with the single pentium III. Am I >correct ? > the rough number I would use is this. If you have a single cpu at 500mhz, and compare that to a dual cpu at 500mhz each, the dual (using crafty) will be roughly 1.75x faster. Note that is a rough number and that an SMP search is highly volatile in nature. It is even possible that in rare positions, the SMP search will actually be _slower_ than the single 500mhz cpu program. >So to the point: The following system was quoted to me: and I have a few >questions in this regard. > >CPU-------------- Pentium III 750D--------(Cyber III-750) what is that mean ? > 133 MHz AGP VIA Is that good ?

The single cpu probably has a faster bus (133mhz). And the cpu does sound like a coppermine processor. It may well be faster than the dual in the average position, and it will _never_ suffer from the funny SMP behavior that really slows it down. My advice would be to always take the single assuming that the dual has two cpus roughly 1/2 as fast as the single. Dual 733's would be dynamite of course. :) > >Junior6: Same question, how would you compare the performance of Deep Jr with a >dual 500 mhz cpu's against Junior6 in the above computer system. > > >Lastly (at last you say) Any suggestions as to a better computer system in that >price range or something close (very) to it. > >Whoops, PS: The graphic accelerator 3d capability is very important for apps >running Flight Simulator 2000 etc. Is the above one excellent for this app. > the cpu is so fast, I doubt graphics will be a problem for flightsim.
