Just done a small and basic test... Not quite real world, but still gives an idea of how the PC copes with a list of jobs.
I did the EXACT same thing on both PCs in the very same order. As I have all my PCs setup in very much the way way, with the same Desktop same Apps etc, I think its a close to fair test as I can do in many ways.
Here are the PCs as they stand right at this very minute...
Intel :-
MB = Asus P5GD1-FM
CPU = P4 3.6Ghz Prescott 660 ( HT Enabled )
RAM = 4x512MB Samsung PC3200
GFX = Saphire x800 @ x850
Audio = Audigy 2 ZS
AMD :-
MB = DFI LanParty 250GB UT
CPU = Newcastle 3000 @ 2.4
RAM = 2x512MB Corsair XMS4400 TwinX
GFX = Leadtek 6800GT
Audio = Audigy 1 LS
In order to make the test a bit fairer, I have a pair of WD200GB Sata Drives, and so, I have thrown XP Home SP2 onto both of them its a fresh install, no more than about an hour old each... I have updated all the drivers, but I have NOT doen any updates, nor are they activated ( Cos they will be wiped tomorrow and their own OS put back on )
Here is what I did
From the desktop, I double-clicked on...
3DMark 2000, 2001, 03 and 05
UnReal Tournament ( Classic ) and then UT 2004
I then clicked on FarCry, and then Quake 4
I then ran AdAware SE, SpyBot S&D, Noadware and Spyware Doctor.
Now, I did all of this as quick as I could, I moved the icon so they were all going down the right hand side of the desktop... This makes no difference in speed as such, but it was just to allow me to double click on them all as quickly as I could.
I did it first on the P4 and then on the AMD...
The AMD brought everythign up in somehtign like about 25-30 seconds, the P4 seems to be hanging there, but I can move the mouse every so often, and the display is still definitely trying to load up more thigns.
The games on the AMD come up, they obviously take priority and I have just played a round in UT Classic ( Morpheus - Skilled - 7 bots ) and had 180-220FPS just fine, no glitches or slowness of any kind.
I quit it, and up came UT2K4, I quit that and FarCry, and then I quit all the 3DMarks and not once did it have any kind of lag in any way. As soon as the last App closed, I double clicked on UT2K4 again and it came up in less than a second.
The P4 however, still has not loaded up any game at all, although it looks like UT Classic is in a fullscreen window at the back ,but the mouse movement is so poor, that I have tried to click on the window, but I dont yet know if it is bringing it up to the front.
TaskManager is showing that UT2K4 and 3DMark2001 are both taking up 50% of the CPU, and that I have not yet taken up 1GB of the RAM, and its definitely updating that as you can see the free memory changing all the time.
----
About 8 minutes into it now, and UT Classic has just displayed the PRECACHING message just before it launches into the game-start demo, so, I have ALT-TABBED and the popup window has come up but nothing seems to be chaning on that yet.
---
Further 4 minutes later, and Taskmanager is back and I am sort of able to move the mouse and highlight the apps, so I am killing off UT2K4 and 3DMark2001, but the system, while better, is still unresponsive, so I have killed off the rest of the 3DMark apps.
So far, the P4 has taken about 15 minutes to fail to start up what the AMD started up, allowed me to play UnReal Tournament with the other junk going on in the background, and then quit everything and then reload UT2K4, dump that into the background, and then type all of this...
And like I said, the P4 is still trying to start some things up!
This P4 is perhaps the most pathetic PC I have seen in a very long time. with the exception of a Celeron.
Its got 50% faster CPU ( In HZ that is ), 400% bigger Cache, 100% more RAM, same HD and yet its so much slower under load than the AMD, and yet the AMD is only a Newcastle, so its far slower than some of my others, its just the Newcastle is right next to the Intel, otherwise I would have used one of my real AMDs.
Utter pathetic.
Given a choice between a fairly top end P4 or a Mid-range AMD, then I would go for the AMD anyday.
