Audio/Video Encoding
MusicMatch Jukebox 7.10
DivX 5.2.1 with AutoGK
Armed with the DivX 5.2.1 and the AutoGK, we took all of the processors to task at encoding a chapter out of "Pirates of the Caribbean". We set AutoGK to give us 75% quality of the original DVD rip and did not encode audio. 
XviD with AutoGK
Another very popular codec is the XviD codec, and thus, we measured encoding performance using it instead of DivX for this next test. The rest of the variables remained the same as the DivX test. 
Windows Media Encoder 9
To finish up our look at Video Encoding performance, we have two tests, both involving Windows Media Encoder 9. The first test is WorldBench 5's WMV9 encoding test.

#88 (not 48 lol)"Pd (3.2) vs X2 (4200+), Pentium D wins price/ performance"
What are you talking about?
PD 3.2 estimated cost is $530 and X2 4200+ estimated cost is $537. Not to mention much more expensive board and DDRII. And X2 4200+ simply smokes to PD 3.2 in basically everything.

Was it possible to drop the multiplier to 11 so we could see the potential performance of a 4400+?PetNorth - Tuesday, May 10, 2005 - link

Sorry about my original post inquiring about NCQ; I failed to notice the PATA notation on the Seagate. Having said that, would you consider comparing the multitasking performance with NCQ enabled and disabled on these new dual core X2s?CrimsonChaos - Tuesday, May 10, 2005 - link
Nice review. I'm in the crowd of those who can't wait for (AMD) dual-core processors to become available. As far as I can tell, the X2 4800 ran games nearly as fast as the FX-55 and outperformed the FX-55 in multi-tasking. So what reason is there to buy the FX-55 once these are released (assuming prices are close)?#84 - I do not think that the background tasks of Anti-Virus and Anti-Spyware programs use much CPU. Aside from the initial launching of the program, the CPU usage to keep the program running is minimal -- if any at all. I was under the impression they just ate up RAM while running. Correct me if I'm wrong?

Anand, was this tested on 32bit version of XP? Wouldn't the #s be even more in favor of X2 should we have the proper drivers and run it under XP x64 OS?Psyched.

Pricing for the X2 dual cores within amd product like makes sense. 4200+ is a tad faster than the 4000+ only in mutlitasking mode, but then that's why you are buying dual cores anyway, for multitasking multithreading.but once you put intel's pricing in the mix, with intel's capacity to just churn out silicon, they can afford to price these much lower. unlike amd, pricing it down to stimulate demand...
the x2's sit in the happy middle of the Pd, and the PEE, and the pricing shows that.
Pd (3.2) vs X2 (4200+), Pentium D wins price/ performance
but X2 (4200+) vs PEE (3.2), X2 wins hands down. which is kinda sad, the 4800+ is not even challenged.
300 vs 500 vs 1000, those are the competing prices for the chips... so it's a bit hairy to compare.
now, dual core 256k or even 128k would be welcomed, as we saw performance betwen sempron 3100+ and the a64 2800+, performace with half the cache is negligable. so if amd makes dual cores with 256k cache or even 128k, that could help with the transistor count and keep the total area small. giving amd some slack in cost, and lower power consumptions. (*but that doesn't necessarily mean lower prices to consumers).

#85... with dueling cores Unreal 3 will suck... the processors will be too busy dueling with eachother to run the game. ;)jkostans - Monday, May 9, 2005 - link
Awesome article. I was reading an article over on tom's hardware on the X2 where they did a little more intensive power consumption test. Here is a quote which really got my interest,"However, there is something that we can't really tolerate: the Pentium D system manages to burn over 200 watts as soon as it's turned on, even when it isn't doing anything. It even exceeds 310 W when working and 350+ W with the graphics card employed! AMD proves that this is not necessary at all: a range of 125 to 190 Watts is much more acceptable (235 counting the graphics card). And that is without Cool & Quiet even enabled."
I just felt this is something anandtech didn't touch on as thoroughly and should really be considered. I mean a 350w PS will fry or shut down using one of these bad boys in a gaming machine. I wouldn't even feel safe with my Vantec 400w PS.

Anand, Please write article showing what futuregames will be like with duel core cpu's and
if with bois updates performance might increase.
future game i.e. UNREAL III
