Business/General Use Performance
Business Winstone 2004
Business Winstone 2004 tests the following applications in various usage scenarios:. Microsoft Access 2002
. Microsoft Excel 2002
. Microsoft FrontPage 2002
. Microsoft Outlook 2002
. Microsoft PowerPoint 2002
. Microsoft Project 2002
. Microsoft Word 2002
. Norton AntiVirus Professional Edition 2003
. WinZip 8.1
Office Productivity SYSMark 2004
SYSMark's Office Productivity suite consists of three tests, the first of which is the Communication test. The Communication test consists of the following:"The user receives an email in Outlook 2002 that contains a collection of documents in a zip file. The user reviews his email and updates his calendar while VirusScan 7.0 scans the system. The corporate web site is viewed in Internet Explorer 6.0. Finally, Internet Explorer is used to look at samples of the web pages and documents created during the scenario."
The next test is Document Creation performance:
"The user edits the document using Word 2002. He transcribes an audio file into a document using Dragon NaturallySpeaking 6. Once the document has all the necessary pieces in place, the user changes it into a portable format for easy and secure distribution using Acrobat 5.0.5. The user creates a marketing presentation in PowerPoint 2002 and adds elements to a slide show template."
The final test in our Office Productivity suite is Data Analysis, which BAPCo describes as:
"The user opens a database using Access 2002 and runs some queries. A collection of documents are archived using WinZip 8.1. The queries' results are imported into a spreadsheet using Excel 2002 and are used to generate graphical charts."
Microsoft Office XP SP-2
Here, we see in that the purest of office application tests, performance doesn't vary all too much. 
Mozilla 1.4
Quite possibly the most frequently used application on any desktop is the one we pay the least amount of attention to when it comes to performance. While a bit older than the core that is now used in Firefox, performance in Mozilla is worth looking at as many users are switching from IE to a much more capable browser on the PC - Firefox. 
ACD Systems ACDSee PowerPack 5.0
ACDSee is a popular image editing tool that is great for basic image editing options such as batch resizing, rotating, cropping and other such features that are too elementary to justify purchasing something as powerful as Photoshop. There are no extremely complex filters here, just pure batch image processing. 
Ahead Software Nero Express 6.0.0.3
While it was a major issue in the past, buffer underrun errors while burning a CD or DVD are few and far between these days, thanks to high performance CPUs as well as vastly improved optical drives. When you take the optical drive out of the equation, how do these CPU's stack up with burning performance?As you'd guess, they're all pretty much the same, with the slight variations between chips falling within expectations. Any of these chips will do just fine.
Winzip
Archiving performance ends up being fairly CPU bound as well as I/O limited. 
WinRAR 3.40
Pulling the hard disk out of the equation, we can get a much better idea of which processors are truly best suited for file compression.

People have been saying that a dual-core processor at the same speed as a single-core one will not speed up games and such, but I beg to differ: In a real-world situation, one would have MS Antispyware and an AV program running in the background, while running a game. Also, don't forget the OS as well as onboard sound, chipset raid, USB, and other various programs. A dual-core cpu, even for single-threaded apps like most games, will pretty much give that game its own core. I am excited to see the dual-cores come out personally.SLIM - Monday, May 9, 2005 - link
Hey Anand,Nice article as always, but why do you think the extreme edition suffers so badly in some of the benches compared to its non-HT brother???
Is it possible/plausible that some of those terrible results are due to the more cpu intensive apps being saddled on the two logical cores of just one physical core? Do you think bandwidth can really explain the huge drops in performance?
Oh and thanks for the overclocking results too.

For those talking about multitasking tests. Look at them carefully and not bla bla bla. I mean: X2 4800+ Vs. PEE 840 and X2 4200+ Vs. PD 840.So, in these 5 Anand multitasking scenarios:
X2 4800+ Vs. PEE 840: 2-3
X2 4200+ Vs. PD 840: 4-1
And don't forget that Multitasking compiling scenario from Opteron DC review is missing in this X2 review: http://www.anandtech.com/cpuchipsets/showdoc.aspx?... Another X2's victory.

Hyperthreading can be a loss when there are memory bandwidth intensive apps. The P4 implementation shares a the data TLB, which ends up thrashing when you have lots of requests that go to memory from both threads.Brian23 - Monday, May 9, 2005 - link
Thank you for the overclocking results!Son of a N00b - Monday, May 9, 2005 - link
I wont be upgrading to a dual core anytime soon, ill stick with my fx55 on water @3000mgz, but when i do go DC its nice to know there will still be a amd heart at the center.pdr - Monday, May 9, 2005 - link
Can y'all start adding some linux tests (32- and 64-bit would be nice) on things like dual core? Everybody seems to think that if you want some oompfh in linux you will obviously want to build a mega-box cluster. But I just want to minimize my kernel compiles (yes, I run Gentoo), video processing (transcode, ffmpeg, mencoder, etc) - I don't want to turn my living room into a data center.Anand Lal Shimpi - Monday, May 9, 2005 - link
For those of you asking for overclocking results, here's what I've seen:Pentium Extreme Edition 840: 3.6GHz was the maximum stable overclock I could obtain with standard air cooling. I had to bump up the voltage by around 5% I believe (it was a while ago so I don't have the numbers fresh in my mind).
Athlon 64 X2 4200+: The best I could do here was just under 2.6GHz (2.53GHz to be exact). This was with air cooling and no voltage tweaks necessary. I couldn't get it totally stable at 2.6GHz.
Take care,
Anand

Anand,Could you run the real world tests with a single-core Pentium to compare against the FX-55?
I'm interested in seeing if there's an issue with how well AMD's platform switches threads. If the Pentium beats out the FX-55 significantly then maybe AMD's platform has trouble switching among huge number of threads. This would mean the X2 would be more suitable for multi-tasking among 2-4 threads where the Pent-D would be more suitable for 6-inf threads.

#61 "hear what you're saying...to me, they don't seem faster but they do seem "smoother". "There is an easy explanation what you are saying, for example a game on intel does 50 to 70 fps.
On AMD 50 to 100 fps.
Who will be the smoother, the one that appears to be working always at the same speed, because the one that will give you higher differences of performance peaks will of course look "erratic".
