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 the source code to Firefox while importing a 260MB PST file into Outlook 2003. You'll note that this is a slightly modified version of the test that we originally created; we modified the test by archiving the Firefox source instead of a single smaller file. The reason for this is that we wanted a more realistic test (from a file size/count perspective) as well as the ability to better discern between contenders.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 Firefox source.
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:
Remember that Windows' scheduler will give, by default, priority to the foreground task, which is why we see such a strong showing from the FX-55 here. But let's take a look at the other main task that ran in the background, the Outlook PST import:
Here, we see that while the FX-55 completed the archive task quicker than the dual core AMD CPUs, it basically got nothing done on the import emails task. Here, the advantage of dual core is clear, and once again, we see that AMD and Intel are very close in performance, but with Intel taking the crown. Interestingly enough, Hyper Threading is a major hindrance to Intel here as the Extreme Edition is significantly slower than the HT-disabled Pentium D 840.

#33 ..agreed..If anything I think AT is more biased towards AMD, not intel
and #32, there is a well known fact that in scientific testing, if you already have a bias towards one outcome (read: amd fanboi) then your results will subconciously show what you set out to say.... that's why in real scientific tests, also known as a "double blind" test, the testers dont know what they are testing and the subejects dont know what they are using ....in this case the subjects are the cpu's so they cant talk :P

#32 Wow... just. wow.crisagatie - Monday, May 9, 2005 - link
This is another Inteltech bullshit. After X2 beating Intel hands down in all tests and benchmarks, these guys put up a bag of their own tests (multitasking scenarios) toped by Intel in every single one. Then they say the results are "a mixed bag", with Intel and AMD performing equally...You, Anandtech guys, read the reviews all over the Internet! And try believing: Intel sucks! X2 is by far the best performer (even X2 4200+), being at the same time a cheaper option to Intel D 840 and EE.

As to availability, I note from the Dell site that the EE 840 isn't available till June 15th either...For applications, I noted in Tech Report's review that they did some very good graphs illustrating results on a thread-basis, and they included the dual Xeon 3.4GHz. It appears that for rendering workstations, the 4800+ blows the doors off of the dual Xeon, at a fraction of the price...
This just caused me to contact a friend who put a big hold on 12 new workstations he was ordering!

Anand, did you happen to do any overclocking with the X2? If so, were the results simular to typical single-core 90nm?I'm sure there is some headroom and 2.6GHz can be achieved with the X2, which would make it untouchable if it scales accordingly.

Scratch my comments about no power consumption tests. How did I miss them? *scratches head* ?????
