Intel's Core 2 Extreme & Core 2 Duo: The Empire Strikes Back

Encoding Performance using DivX 6.1, WME9, Quicktime (H.264) & iTunes
Multimedia encoding is typically a very good CPU benchmark, with performance that scales very nearly linearly with faster CPU clock speeds. Video testing was conducted using three popular codecs and applications: Xmpeg 5.03 with DivX 6.1, Windows Media Encoder with WMV9, and QuickTime 7.1 with H.264. The complexity of the encoding process increases as we move from DivX to WMV9, and H.264 encoding is in a league of its own in terms of the amount of CPU time required.
In something of a change, both the Core 2 Extreme and that E6300 manage roughly a 25% margin of victory over their AMD counterparts in the DivX test. The E6300 very nearly matches the X2 5000+ here. The X6800 maintains the 25% lead in WMV9, while the E6300 lead over the X2 3800+ drops to 8.5%, roughly equaling the 4200+. Finally, in H.264 encoding, the Core 2 Extreme claims one of its largest victories coming in 36% faster than the Athlon FX-62; the E6300 also manages a large 21% performance lead over the X2 3800+ and falls between the 4600+ and 5000+ in performance.
Moving over to audio encoding performance, we used Apple's iTunes 6 application to encode a single 307 MB Wav file into a 192kbps MP3. Audio encoding is still very CPU intensive, but of course the faster encoding times make the differences less noticeable in practical use. At the top and bottom price points, Intel leads again: 5% at the low-end, and 15% at the extreme performance segment. Unless you frequently encode really large amounts of audio files, however, it's unlikely you're going to notice Intel's 2-4 second lead.

The first nF4 Intel Edition boards will be available the week of 7/20. The nForce 500 boards for Intel will not be available until early August. We are now under NDA for the nForce 500 until NVIDIA makes their release announcement. However, there are a couple of nForce 500 boards that look very promising at this time. Do not expect high FSB overclocking results until NVIDIA's next chipset but overall performance is very good at this time.mobutu - Friday, July 14, 2006 - link
Thank you very much for the info you shared.Still, one more question: what do you mean "nVidia next chipset"? Like nF6 or smtg? Because if so it means probably Q4 2006 or Q1 2007 ...

The one that will come out this winter that we cannot discuss except for the fact that it will be a single chip and dual x16 capable. :) Of course, no real mention of it so far but ATI has a really nice Intel chipset due in late August to early September followed up by a refresh in the winter also.mobutu - Friday, July 14, 2006 - link
Oh, I got it. Thank you very much, much appreciated.Looking forward to see Anandtech review of Conroe motherboards.

you really need to include scores for 4ghz conroes, and maybe some 3.2ghz x2s(though this isnt really needed) and your review will be the most perfectest one evar!JarredWalton - Friday, July 14, 2006 - link
We generally reserve overclocking scores for articles specifically looking at that aspect. It's unfair to include OC'ed Core 2 without OC'ed X2, FX, etc. I hope to get a Core 2 in the near future to run some specific OC benchmarks comparing a lower end (E6300 and/or E6600) Core 2 with X2 3800+ (hopefully EE, but we'll see).junior1 - Saturday, July 15, 2006 - link
Jarred that would be great to see. The E6300 and X2 3800+ seem close, but the final AMD pricing and the overclocking potential of each could really make either the clear winner for performance per dollar in the midrange segment.
Is the die size smaller on E6300 and E6400, or is it a full die with half the cache disabled? Any chance the smaller cache means better OC potential?
It would be great to see results with several chipsets.

awww. At least give us a taste, maybe 2 or 3 of the most CPU intensive tests run at 4ghz.Gary Key - Friday, July 14, 2006 - link
Just wait a few days.... :)mendocinosummit - Friday, July 14, 2006 - link
Ya, that is what I was hoping for. I want to see a dual core (that has some balls, unlike the preslers) run at 4ghz and do some benchmarks
