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.

just to show you how EASY it is to O/C the system! (and for the Futuremark junkies :-) )http://www.futuremark.com/forum/showthread.php?p=1...">http://www.futuremark.com/forum/showthread.php?p=1...
You would want one :)
if you want to know, 3DMark 2001SE posted a score of 45k, and 3DMark 2003 posted a 33k, FACTORY.

I was wondering if you could possibly do some "single core" performance testing in the CPU's by simply changing the HAL to "ACPI Uniprocessor PC" instead of "multiprocessor PC" This would tel windows to only use one of the Core2 Duo cores, and I think would give us a good indication of how it will perform when released. Especially on the 2MB cache models, since I'm guessing the single cores won't bust out the door with a full 4MB.Just some food for thought/consideration. I personally would love to see a few tests run this way and compared to some single/dual core A64's.

Conroe-L is so far off that it's really an afterthought. The only reason it's not shipping is that Intel has a ton of Netburst stuff to offload, IMO. At $145, the PD 945 is still interesting in terms of certain computational tasks. (I miss the QMD Folding@Home cores....)fishbits - Friday, July 14, 2006 - link
I had hoped AMD could gain even more market-share before something like this happened, would rather see the two CPU makers on more even footing. Intel just hit this one out of the park however, if pricing holds and availability is decent. Was looking at upgrading my 3500 (939) to a $300 X2 4600 after the price drop, but now? It looks like I'll probably keep this system and build a new rig around a $300 Intel 6600, which wins over or smokes the 4600 depending on benchmark. I really don't know what AMD can do to keep me in the short term, because I don't know if they can make any money dropping prices as far as it looks like they'll need to go.SpaceRanger - Friday, July 14, 2006 - link
One thing to consider though, if you decide to go with the C2D 6600, then you will also have to spend $$ on a new Mobo + Memory (since your DDR RAM won't work on the platforms for C2D. Keep that in mind when you're upgrading.fishbits - Saturday, July 15, 2006 - link
When I said that if I went with Intel I'd keep my current rig and build a new one around the Conroe, didn't it dawn on you that I'd already "considered" the need to get a new mobo, memory, etc?SpaceRanger - Sunday, July 16, 2006 - link
Holy arrogance.. EXCUSE ME for pointing something out..epsilonparadox - Friday, July 14, 2006 - link
Well the loads of money they made when they had the better performing architecture can hopefully keep them doing very well also the Opteron isn't really being challenged and thats really their moneymaker right now. They shouldn't have any problems lowering prices on their desktop chips while keeping the status quo on the Opterons.zsdersw - Saturday, July 15, 2006 - link
They can't really keep the status quo on the Opterons either. Woodcrest excels (or, at the very least, is equal to the Opteron) in the 1P and 2P server space.. which is a huge chunk of the overall server market.LoneWolf15 - Friday, July 14, 2006 - link
While I'm sad to see AMD lose the performance crown, I'm not so obtuse as to deny it's happening.I'm excited by Intel's newest chip, but I think the results for me will be that I'll buy a faster Athlon 64 X2 when the prices drop (assuming Socket 939 ones become cheaper as well, I don't plan a move to Socket AM2 for some time to come). So Intel's newest chip should benefit even those of us sticking with an AMD system. :)
