Multitasking Scenario 2: File Compression
For our next test, we simulated what would happen if we performed two disk intensive tasks at the same time: zipping a file while importing a 260MB PST file into Outlook 2003.
We ran the same Firefox and iTunes tasks from the last test again, and then did the following:
1) Open Outlook.
2) Start importing 260MB PST.
3) Start WinRAR.
4) Archive 130MB test file.
WinRAR remained the application in focus during this test.
Here, we looked at two metrics: how long it took WinRAR to compress our test file, and how many emails were imported into Outlook during the time that WinRAR was archiving. Let's have a look at the results:
The Pentium D did slightly better than the Athlon 64 in the WinRAR test, but as expected, had well over twice as many emails imported into Outlook by the time that the test was over. Even the Pentium 4 630 also managed to import significantly more emails than the AMD platform.

the power consumption is a series mofo here.hm, with a P4 EE or PDEE, with 2 6800Ultra or GT, you're definitely expecting an oven case.
Wonder how those dualcores overclock-->that should help to make up the single thread performance. On the other hand, Clearly HyperThreading is GOOD, but AMD still says NO.

Great article. Well done guys.The only thing I have to question is how a dual core Athlon-64 at encoding. On the last page you say, "For encoding performance, you still can’t beat the Pentium D. Even a dual core Athlon 64 isn’t going to help enough in that area."
What makes you think that when the 2.2 GHz Athlon-64 is RIGHT behind the 3.0 GHz Pentium 4 630?
Everything I've read so far has told me that the Athlon-64 should scale better than the Pentium 4 as far as dual cores are concerned... so... what exactly are you basing your opinion that even a dual core Athlon-64 won't help in encoding???

Does http://www.anandtech.com/cpuchipsets/showdoc.aspx?... page have an error?It lists the PD 3.2, P4 3.73 EE and the PD 3.2 EE, not the 3 CPU's montioned in the article. Wrong graph maybe.

Holy crispy power and cook my eggs in true multitasking while I surf the net Batmansmn198 - Wednesday, April 6, 2005 - link
I guess it makes sense that NCQ would help when multitasking. I assume that this would be the same on single cores as well? The new focus on responsiveness is a good move IMO. The time to switch between apps and redraw the screen and clicking on menus and buttons is what frustrates me when I am multitasking.
