For a single threaded CPU, that means that certain tasks will take much longer to complete simply because the OS' scheduler isn't giving them a chance to run on the CPU.

The problem in situations like these is that the Windows scheduler won't always preempt one task in order to give another its portion of the CPU's time. The reasoning behind this is more of an issue with the Windows' scheduler. You'll also note that the Athlon 64 X2 4200+ completes the DVD Shrink task in less than half the time of the higher clocked single core FX-55. The performance of the single core Athlon 64 FX-55 is dismal compared to any of the dual core offerings. Below are the results:ДЄs we showed in the first set of dual core articles, tests like these are perfect examples of why dual core matters. We waited until the DVD Shrink operation was complete and recorded its completion time. There is still quite a bit of Flash, but the load is much more realistic now.ДVD Shrink was the application in focus this matters because by default, Windows gives special scheduling priority to the application currently in the foreground. This time around, we have a wider variety of web content open in Firefox while we conducted our test. In the first review, our stored web pages were very heavy on Flash. This test is a bit different than the test that we ran in the Intel dual core articles, mainly in that we used more web pages, but with more varied content. All default settings, including low priority. We kept the browser on the AT front page.Дў) Open iTunes and start playing a playlist on repeat all.ДҐ) Login to our news server and start downloading headers for our subscribed news groups.Д¦) Start backup of Star Wars Episode VI - Return of the Jedi. 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.ДЎ) Open Firefox using the ScrapBook plugin loaded locally archived copies of 13 web pages. We ran DVD Decrypt on the Star Wars Episode VI DVD, so 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). The encoding can easily take between 20 - 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 larger.ДЇor 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. Just ripping the disc to your hard drive will eat up a good 20 minutes, and then there's the encoding. If you've ever tried to back up a DVD, you know that the process can take a long time. In the end, our previous tests have shown us that no single core CPU can compete with even the slowest dual core CPUs in any of these tests. We have already looked at Intel's dual core scalability in previous articles for those who are interested. Intel dual core scaling in another article, so for now, we are comparing the dual core chips featured in this article to the fastest single core AMD CPU - the Athlon 64 FX-55.

Both the AntiSpyware Beta and NAV 2004 were running with their real time protection modes enabled, to make things even more real world.

What's important about that list is that a handful of those programs were running in the background at all times, primarily Microsoft's AntiSpyware Beta and Norton AntiVirus 2004. Norton AntiVirus 2004 (with latest updates) We started with a test bed configured with a number of fairly popular applications:

In the end, we know that dual core CPUs make our systems much more responsive and provide the same sort of smooth operation that SMP systems have done for years, but the question now is - who has better multitasking performance? AMD or Intel? And that's exactly what we're here to find out. We've already gone over the impacts of dual core CPUs on subjective interactions, so we'll just point you back to previous articles for our take on that, if you haven't read them already. Based on this information, we formulated some of our own benchmarks that would stress multitasking performance. The Real Test - AnandTech's Multitasking ScenariosД«efore our first dual core articles, we asked for feedback from the readers with regards to their multitasking usage patterns.
