quick query which of these is more powerful

[Clark the White]

Hi folks,

can someone please tell me which of these processors is more powerful overall?

also if anyone can give me a rough percentage of the difference that would be good.

Intel(R) Core(TM)2 Duo CPU L7500 @ 1.60GHz (2 CPUs). - (a Laptop processor)

VS

intel(R) pentium(R) 4 CPU 3.00Ghz (2 CPUs) -(a DESKTOP processor)
(from a Dell optiplex GX620)

Also if anyone knows, which would be better for running Folding@home?

the reason I am asking is that at work we will be getting these naff (not performance-wise - I mean as in physically small and annoying - especially the display and keyboard compared to the desktop I currently use.) laptops and if it is at least better for folding then it would be a small consolation.

I would say in multithreaded apps and for folding the Core 2 Duo would be faster but in single threaded apps probably the P4.

IIRC there were no dual core P4's, so it's just a single core with Hyperthreading.

I would avoid a P4 based laptop personally.

[Updated with other likely models]

There's a 3ghz Pentium 4 631 which shows on the Tomshardware charts as being dual-core...that could be the model Clark means. Just sifting through the charts and trying to find identical tests in both their mobile and desktop listings you get some of the following:

3dmark06 cpu test
L7500 - 1427
P4 631 - 904
Pentium D 830 - 1330
Pentium D 930 - 1330

PCmark05 cpu test
L7500 - 4036
P4 631 - 3770
Pentium D 830 - 4956
Pentium D 930 - 4990

Cinema 4d rendering
L7500 - 412 seconds
P4 631 - 659 seconds
Pentium D 830 - 407 seconds
Pentium D 930 - 408 seconds

Quake 4
L7500 - 68.2fps
P4 631 -50.6fps
Pentium D 830 - 66.9fps
Pentium D 930 - 65.7fps

There's no info about other system components though so I'm not sure how comparable they are really.

EDIT - Not quite so clear cut any more with those extra results.

 

[Yamahahahahaha]

Well, looking at those test results, get the L7500. There's no argument.

 

[Fothsn]

The P4 will have HT so its 2 threads not cores. HT = Hyper-threading.

 

[Emlyn_Dewar]

The P4 is a hot, dated POS. The Core2 would be the more powerful CPU.

 

[Nullvoid]

Actually it's more likely to be a Pentium D 830 or 930, surely they're true dual-core models and both are 3ghz?

 

[Fothsn]

It could very well be a Pentium D which are dual core CPUs basically 2 P4s stuck together so are very hot and insufficient at what they do, just a way of Intel saying they had a dual core CPU but there were rubbish, I would get the Core2 chip every time without a doubt, remember it isn’t about clock speed more the architecture and the Core2 wins hands down.

excellent thanks for the replies and benchmarks folks much appreciated.
