Something Ive wondered (cpu speed)

post #1 of 8
Thread Starter 
As im still not sure exactly what build Im going for this summer, like most Im torn between getting the Q6600 when the price drops, vs something else (core 2 of some sort). Anyways, Id like to know about raw processor speed.

After reading alot on here, and learning much of my knowledge, it seems the Q6600 (which is stock at 2.4ghz) can get up to about 3.0ghz on air as most people have reported. However those with C2D's have posted much higher raw ghz speeds anywhere from 3.1ghz to 4.0+ghz.

So basically its this --> a Q6600 oc'd and running at 3.0ghz VS a C2D oc'd and running at lets say 3.5ghz, VS my current P4 oc'd and running at 3.9ghz. What would be a good way to analyze these as far as which could run a typical game better ? (for arguments sake, we'll say Company Of Heroes) ..

Im kinda worried that if I choose the Q6600, I wont be able to oc it high enough to perform well. If I go with the C2D, I can get a higher raw speed.

If the answer is obvious (the Q6600 has 4 cores which would make it insanely faster even though the raw speed is much lower) then please explain that, as I am still learning :-)

Thanx in advance.

The problem is that most games don't take advantage of all four cores, thereby they will actually run faster with the OC'd dual core processor you talk about. However, I think Company of Heroes was developed with quad core in mind. Supreme Commander might be another.

Thanx Lost !!

But what Im really looking for is an explanation of the cpu itself, what it can do, and how the speed its running at relates to the performance it can give.
Basically is a quad core running at 3.0ghz better to have than a c2d running at 3.5 or higher ? How important is the actual speed overall ... yes, the higher the better obviously, but in relation to the cpu itself ?

Just trying to make the best choice .. I certainly dont want to get a q6600, get it around 3.0ghz, and still have slowdown or non-maxed results in games, when I could have went with a c2d, and gotten better results.

Lol I am not feeling like explaining but I will say something that you have to think.

If Core2Quad @ 3Ghz less powerful than a Core2Duo 3.5GHz then Core2Duo 3.5GHz less powerful than a P4 4GHz. So that means that my secondary rig will be much more powerful than those new quad cores.. WRONG THINKING!!!

I will bring you an exampole to let you understand. Pentium Dual Core is a highway with 2 traffic lines, C2D is again a highway with larger traffic lines though and quad has the same wide traffic lines and it has 4. Today most games and programs do not need to use 4 traffic lines so a quad will most probably not get filled. Its not wise to compare things that are not the same. Remember a quad is not useful right now because not manyu things are programmed to work on them but next year probably it will be exactly what you need.

A Core 2 Duo processors and quad cores at 3GHz is more like a P4 Prescott core at ~5GHz.

The comments with regards to quadsd being a waste, games are now becoming multithreaded so will take use of the quadcore processors.

One example that springs to mind is Supreme Commander. My LAN buddies Quadcore (Q6600) 2GB of RAM, and dual 8800GTX can even struggle when running 4v4, 81KMx81KM maps.

You can't compare a P4 with A C2D. The dual core technology be it virual or not lets you do 2 different things the same time while 1 core lets you do only one. If you try copying a big file and doing something else on a P4 since the CPU will keep switching from one task to another they will slow down, on the other hand dual core CPUs will let these two work normally since they will be using a different core. Again its bad to compare somethiung that its totally different.

Put it this way

The p4 does 6 ops per cycle (ghz)

The C2D is estimated at around 12 (there is no exact number as of yet)

But for a p4 to keep up with 1 core on a c2d it will need to be running twice the speed. But don't forget C2D has 2 cores compared to the p4's one core.

Most games that come out now will be multi threaded so it will take advantage of both cores. With this is mind i will give you example

C2D @ 3 Ghz

For a P4 to even compete with (1) of the C2D's cores it will need to be running @ 6Ghz

However when in a multi threaded app it will need to be running at about 12Ghz (because it will need to make up for the lack of 1 core)

The Q6600 is just 2 E6600 slapped together.

But i doubt may games willbe threaded for 4 cores anytime soon (except for alan wake)

However it would be wisetoinvest in one if you do other things besides game.

This is only an estimation, do not take any of it as hard fact

Your referring to the change of technology. If you want then I will restate what I said by comparing a P4 with a PentiumD. Both have their cores based more or less on the same technology. Even then P4 can;t compete with a D because the D can do 2 things the ame time with no sweat. The only way to make a P4 compete with a D is to raise the clocks to a point that it will be able to do the work of each task in half time that 1 of the cores of a D will need to complete it. In that case since it will take half the time to complete a task then it will be the same as a pentium D..which ofcourse is kinda crazy,,
