Intel Dual Core Performance Preview Part I: First Encounter

Multitasking Scenario 3: Web Browsing
For our final benchmark, we decided to switch things up a bit and keep Firefox as our foreground application while background tasks ran. To make things even more stressful, we had no less than 12 tabs open in Firefox, with our main tab being IGN's PSP website - which happens to be very Flash heavy.
The iTunes and Newsleecher tasks from the first test scenario were also present in this one, plus we did the following:
Open Outlook, immediately import 130MB PST file and immediately switch app focus to Firefox.
We then recorded the total time required to import the new PST while Firefox was our foreground application. The results were very interesting:
The most surprising is how poorly AMD did in this test. We actually had to exclude them from the graph as it distorted the bar lengths too much. AMD weighed in at over 27 minutes; from actually using the system, it looks like Flash takes a much bigger performance toll on AMD platforms than it does on Intel. The end result is that the scheduler devoted very little time to the Outlook process, resulting in the import taking an extremely long time.
Ignoring the AMD outlier, dual core offered serious performance improvements over single core within the Intel realm alone. The 840 completed the PST import in around 70% of the time of the 3.73EE. Again, the gap would grow if more tasks were running, or if we were actually interacting with Firefox instead of just sitting there and reading one page (we confirmed this by actually doing it, but it is a little too difficult to do in a repeatable fashion for testing purposes).

AMD's dualcore will use less power and produce less heat apparently and last I checked an FX-51 (2200) out performs the Intel 3200 in a single core configuration so it will be interesting what a dualcore AMD at 2200 or 2400 will do compared to the Pentium 4 3200 dualcore. AMD is going after the busines market where the money and the desire for dual core will be greatest. Why isn't Intel going for that market? Interesting question.CrazyCurl - Monday, April 4, 2005 - link
good review! cant wait to see more info. I am particularly interested in heat dissapation as well and would be nice to see the new unreal engine that supports multithreading benchmarks but that would be be a ways off id assume.Is the 955X gonna support pressler? is that why it has 1066 fsb and ddr-667?

How about a web developer test I constantly run these programsDragonflycms 9.1.2
Apache 1.3.9
MySql 4.1
PHP 4.0
Photoshop 7.0
Flash MX 2004
Fireworks MX 2004
Dreamweaver MX 2004
Firefox
Hydra IRC
Messenger
Yahoo Messenger
The web server and mysql drastically effect the runing of the multimedia applications. This would be a great multitask test.

#34 You are absolutly right there Anand, to this day I have still not had a single CPU system as responsive as my old dual O/C Celeron 550 machine. I ran it along side a P3/800 for a long time and always much prefered the Celeron box for general day to day tasks, hell my AMD 3500 feels damn fast most of the time but when I try multitask a bit too much it just takes forever to even get menus to pop down. Dual core is definately the way to go for the future, when the apps/games start to catch up with the technology everyone will wonder how they ever did without a multi core/cpu system.stephenbrooks - Monday, April 4, 2005 - link
If it's any help to y'all asking about thermals, [H]ard|OCP says:"Our Intel 840 will have an operating voltage between 1.2V and 1.4V and have a Thermal Power Design of 130W"

thanks Anand... it is the power consumption and power dissipation profiles that I really want to see.Anand Lal Shimpi - Monday, April 4, 2005 - link
oh and power consumption is coming... :)Anand Lal Shimpi - Monday, April 4, 2005 - link
Hans MaulwurfThese usage scenarios were described by AnandTech readers in my recent request for benchmarks, they weren't anything prescribed by any hardware manufacturers.
Ask anyone who has used a dual processor system, things are just smoother. The reason we've never recommended dual processors systems in the past is mostly because of price. In less than 3 months you should be able to, in theory, purchase a dual core processor for as little as $240. Not since the days of the dual Celeron 300A systems has dual processing been that affordable.
Take care,
Anand

The best thing about dual core is that you do not need HT aware OS's anymore. It sucks when you want to run Win2000 with HT and getting slower speeds.Shlong - Monday, April 4, 2005 - link
Instead of trying to take screenshots, maybe you could've used one of those desktop video capture programs to try to get a better visual representation of what you were trying to explain.
