more cores less ghz / single core softwear???

[semajjames]

ok my installed cpu is a e6750 2.66 ghz

if i upgrade to the quad q6600 running at 2.4 ghz

will the softwear i have that can only use one core

find it harder work

cheers

Given equal instructions-per-clock, then the 2.4 quad will indeed run single threaded applications slightly slower than the 2.66 dual.

There's all sorts of things you can do with that quad to make it faster though

 

[panyan]

i went from a dual core 3ghz to 2.6ghz quad core and the apps that are only single core were slightly slower, but the system as a whole was a lot snappier

 

[semajjames]

ok what it is

i have 2 apps i need to run at the same time

my 2 core is maxing out

so if i was to get the 4 core

is there any way i can tell 1 app to use core 0 and 1

then tell the other app to use core 3 and 4 or at least stop the second app using cores 0 and

1

this is it i know the q6600 if a good cpu

what would lets say a half way to max overclock take the q6600 2.4 ghz to
running on standard cpu fan

 

[semajjames]

what is the difference between a "G0 Q6600" and a "q6600" ??

 

[RJC]

In theory no difference, but there was a older version of the cpu which was a B3 stepping which was slightly more power hungry. The G0 is the newer version and only 95w weres the other one was around 125w.

Actually Windows 7 has that option. You just need to open task manager, then go on the processes tab, and then right-click on the program and then select "Set Affinity", then you can select which core(s) to use with that program.

 

[semajjames]

thats great thanks

i knew id seen something like that before

i actuall fact xp can do that also ,,,,,,

You shouldn't have to worry about setting affinity usually though, windows sorts it out itself.

Back in the early days (2003) I found that compressing a ripped DVD using Xmpeg didn't max out both CPUs on the dual CPU Pentium 2 system I was using, but if you ran two copies of it at once and set the affinity in task manager to distribute them then overall they would complete faster.

I also once set Adobe Premiere to encode on 4 cores (i7 920) and played GTA4 on the other 4. Obviously the video encoded slower but I was able to play the game so well that I forgot the video was still going. I think if I left Windows to sort that out the heavy encoding task would have slowed the game down too much.

Worth noting that not only does the E6750 have higher clockspeed than the Q6600, it also has higher bus speed as well. Unlikely to make much difference but something to bear in mind.

Personally I'd take a Q6600 over a E6750 due to the extra cores however it wouldn't be the biggest of upgrades, I'd only do it on the cheap.
