Multitasking Scenario 1: DVD Shrink
If you've ever tried to backup a DVD, you know the process can take a long time. Just ripping the disc to your hard drive will eat up a good 20 minutes, and then there's the encoding. The encoding can easily take between 20 and 45 minutes depending on the speed of your CPU, and once you start doing other tasks in the background, you can expect those times to grow even longer.For this test, we used DVD Shrink, one of the simplest applications available to compress and re-encode a DVD to fit on a single 4.5GB disc. We ran DVD Decrypt on the "Star Wars Episode VI" DVD so that we had a local copy of the DVD on our test bed hard drive (in a future version of the test, we may try to include DVD Decrypt performance in our benchmark as well). All of the DVD Shrink settings were left at default including telling the program to assume a low priority, a setting many users check in order to be able to do other things while DVD Shrink is working.
We did the following:
1) Open Firefox using the ScrapBook plugin loaded locally archived copies of 13 web pages; we kept the browser on the AT front page.
2) Open iTunes and start playing a playlist on repeat all.
3) Open Newsleecher.
4) Open DVD Shrink.
5) Login to our news server and start downloading headers for our subscribed news groups.
6) Start backup of "Star Wars Episode VI - Return of the Jedi". All default settings, including low priority.
This test is a bit different than the test we ran in the Intel dual core articles, mainly in that we used more web pages, but with more varied content. In the first review, our stored web pages were very heavy on Flash. This time around, we have a much wider variety of web content open in Firefox while we conducted our test. There is still quite a bit of Flash, but the load is much more realistic now.
DVD Shrink was the application in focus. This matters because by default, Windows gives special scheduling priority to the application currently in the foreground. We waited until the DVD Shrink operation was complete and recorded its completion time. Below are the results:
In this test, the Athlon 64 X2 4400+ does better than the Pentium D 840, but the Extreme Edition manages to offer slightly better performance. A faster X2 shouldn't have much of a problem remaining competitive, however.

Sounds like computing could change a lot in the next 6 months.I can't wait to get my hands on a dual core chip - that type of multitasking gaming performance is what I've been waiting for... 92% of unfettered performance during Doom3? That's unbelievable.

Another thing to consider is that the 939, and 940 Dual Cores work with old mobos. so that saves upgraders ~$100 for the mobo (I have no clue what PD mobo's are going to cost) plus the cost of DDR2 ~$100 for 512MB, not true if you're going with the PD. So if you own a 939 a 2.8 PD will realy cost you ~$441, 3.0 -$516, 3.2 ~$730.Throw that out the window if you're starting from scratch however.

Great review very detailed, I have one caveat, and I should preface it with the fact that I own 4 systems, and all of them have Athlon 64's or XP's.That being said your "Multitasking Scenario 2: File Compression" Seems to be misleading, and identifies the A64 as the processor of choice in the 2nd portion of the analysis.
Maybe I'm wrong but from what I understand with how the test was performed you archived the file, got the amount of time it took to archive the file "x" for instance, and then figured out how many emails got imported in time "x" now because some processors took longer to create the archive than others they had more time to import emails. so in order to make this data more reflective of the performance of each processor you need to divide the number of emails imported by "x", and get e/s. The modified graph should be
PD 3.2 =19124/5.08 or 3764.57 e/s
A64 X2 =21687/6.25 or 3469.92 e/s
PEE 3.2 =16875/6.65 or 2537.59 e/s
AFX 55 = 3800/5.88 or 646.26 e/s
These corrected numbers show that at least in this test the PD 3.2 is the winner by ~8%

At that prices, most of the users really won't need their current mainboards for new dual core processors. I would prefer to have lower priced single core than that prices on dual core.blckgrffn - Thursday, April 21, 2005 - link
We are talking about by this fall, folks. And a 90nm Dual core still uses LESS die than 2 2800+ put together because it is on a manufacturing smaller process, especially if they stick to a 512k cache which is obviously the sweet spot. By this fall I expect that we will see sub $200 dual cores from Intel to squeeze AMD on the desktop market. What is a real shame is that AMD doesn't have suffcient fabs to handle potential demand.For those of you who got all hot in your pants and said I can't buy a sub $200 dual core Intel right now, it is just as true that I can't buy one it all! ;P Chill!

Am I mistaken in thinking that AMD was throwing out their desktop dualcore line (A64 X2) in 2006? What prompted their earlier release of them? Was it the demand for desktop dualcore, pressure from Intel stealing desktop dualcore market, or excellent manufacturing at the AMD plants?KeithDust2000 - Thursday, April 21, 2005 - link
blckgrffn, "so if they can't bring anything out under $200 I will probably have to go with Intel. Boo for that ;) "INTEL doesn´t have one under $200 either.

#14... all socket 939 motherboards will support the X2 with a BIOS upgdate.Zebo - Thursday, April 21, 2005 - link
#9 They'd have to release a 1.6 @ $240 to accurately compete with Intels slowness in Pentium D's starting at $241. Sorry not gonna happen. AMD not for budget shoppers anymore but those interested in performance. Want the best? Pay the price. Or substandard CPU at a discount?I can see a 1.8 for about $250 though however no way you're going to get into DC for less than $200.
