how to compare core 2 quad's and core 2 duo's speeds

post #1 of 15
Thread Starter 
how do we compare the speed of a "Quad core" Intel processor to "core 2 duo" processor ? for example Q6600 overclocked to 3.0ghz is equal to what speed of E6850 in ghz?

It all depends on waht your doing... if your folding then you also need to account for the chache sizes and levels, then if you're using SMP or clients etc... It all depends on the usage there is no real apples to apples comparrison...

if you do many intensive tasks at once the quad could make a big difference. but if you play one single threaded game and nothing else than it would be no difference in performance... it all depends

According to SiSoftware Sandra, for example:

An E4300 overclocked to 3.6GHZ+ will have the same Arithmetic power as an Q6300 at stock speeds (1.86GHz).
From that, my guess would be to get the same Arithmetic speed of Q6600 at stock speed, you would have to overclock an E4300 to 4.8GHZ+.

Basically, double it.

Core 2 Duo: 2GHz per Core, 2 Cores, so, 4GHz of Power (2x2=4)
Core 2 Quad: 1GHz per Core, 4 Cores, so, 4GHz of Power (1x4=4)

So, it would take a 2GHz Core 2 Duo to match a 1GHz Core 2 Quad in multi-threaded applications that actually use more than one core.

Impossible to say as it depends if it's a multi threaded app or not.

In single threaded applications a Q6600 at 3.0Ghz would perform the same as an E6850 at its stock clocks. When it comes to multiple threaded applications this would vary from program to program, depending on weather the application supports more than two cores and exactly how much of each core is actually utilised.

Then just assume they're all quad ready.

After all, somebody who's considering buying a quad core is probably going to do something that utilizes it, no?

If that is the case then i think Quad core is a better deal because Q6600 @ 3.0gz = 6.0ghz in total where as i havnt seen a core 2 duo cpu at 6.0 bloody ghz !
