Hi Ive just build two computers and for some reason my dual core is faster than my quad?? here are specs:

1st computer
AMD athlon daul core (2.9 gh)
1 gig of 800 ram
ASUS m4a785-m
onboard graphics
450 watt power suply
250 gig hardrive
average disk read and burner
windows seven home premuim 32 bit

2nd build
AMD athlon 2 620 quad core (2.6 gh)
1 gig of 800 ram
Gigabyte ma785g-ud3h
onboard graphics
500 watt power suply
120 gig hardrive
average disk read and burner
windows seven home premuim 64 bit
 
Depends on the apps you are using, the majority of applications are only single or dual threaded and as such the faster dual core will perform better, however if you were to have them encode a video or something similarly multithreaded the quad will win by a good margin.
 


Well, i can point out a few things.

First the cpu stock speed of the dual core is 300MHz faster than the quad.

second how are you running 64 bits windows 7 only on 1 GB of ram? The minimal requirement is 2gb of ram on a 64 bit os....

but when i went to install 32 bit on the quad core it sits right beforce the actaul install screen opens and is extremly slow to get windows to install compared to the daul core (like and extra ten minutes slower)
 
well the 120GB hard drive will be a fair bit slower than the 250GB in the dual core so that is also another slow down as a windows installation requires transferring a ton of data. Another GB of ram in each system would make them both run significantly better.

Because you have so little memory. More disk access, switching in and out of memory. The dual core with its higher frequency and faster disk is doing this faster.
Its compounded reasons. Hence the balanced computer runs the fastest.

The 300mHz could do the difference and the speed of your cd/dvd drive maybe have something to do.

ok thanks but my 120 gig hard drive is sata and the other 250 is ide is shouldnt i get faster reads on my sata hardrive no matter how much smaller it is
 
no, SATA just has a higher overall bandwidth, but the transfer rate is related to the speed, and platter density of the drive itself. The interface only affects performance if it gets saturated and there arent many smaller drives that will saturate an IDE connection so that is not a limitation.

Now that you have windows installed, d/l hdtune and take a look at the #'s. you can tell us to help solve the mysteries your wondering about.
