My new X2 4200 seems to run alot slower than my 3700 and they have the same clock speed. The 3700 has 1 mb l2 cache but does that make all the differance?

It shouldnt be slower, it should be the same speed, as only one core is needed for single threaded applications, like surfing the net. In games and mutli threadsed apps is were you will notice the difference. And in multitasking aswell.

Yea it does make a 5-10% diffrence i belive. I thought teh 4200+ only had 512kb l2 cache on both cores to make it 1mb cache. Or is it 256kb l2 on both...

People never realise this when they buy Dual Core processors is that the individual cores are inferior to a proper single core CPU, so if your running single threaded applications the true single core will perform better. But in a Dual Core enviroment it will pwn a single core chip, but not by much imo

You may want to check this thread I created on Dual core fixes and how to make sure your win xp sp2 makes full use of your cpu..There are several links to follow and I noticed a considerable difference in the overall performance of my machine when I applied ALL of the needed hot patches..Read through all of the links and apply whats needed

Provided that the individual cores are at the same speed performance should be the same for most appss. (single threaded). Cache will make a small difference, but not one you will easily notice. Any evident slowdown will be caused by Windows itself (if it fails to properly juggle dependancies and processes between the two cores).

Not quite... you never ever have just one single thread running. OS, network, anti-virus, background tasks, ect are always running. A dual core allows off loading those tasks to help improve performance of that primary app's single thread. Also, dual core processor will beat a single core by 80+% in a optimized multi thread app.

It's possible that you're running newer or more programs than before so you perceive that it is slower. Who knows, maybe you've installed several programs on your machine that are system resource hoggers? Do you still have your old 3700? If you pop that back in, I think you will notice a difference now. There's also a small chance that the programs you were running on the 3700 before were strictly single threaded cache intensive programs?

I haven't loaded anything that wasen't there before. I did all the hox fixes and driver and optimizer and it just seems slower for some reason. When i put in my x2 i had to call microsoft to get a new key to boot windows and the guy on the phone said i would have to call every time i change my cpu (i dont know about any other parts) so im not gonna do that again.

EDIT: I guess i was just mad cause my 3700 would hit 3.0ghz and my x2 won't hit 2.5.. im gonna cry now....

They don't realize this, because you just made that **** up. lol.

dual core is literally 2 cores on the same die.

Intel goes one step further, and uses shared cache.

Either way, the dual core SHOULD be faster, because you can take the load of an individual core, and let one do what it's gotta do and only that...
