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.

Sorry but the Netburst stuff is STILL garbage. Core 2 is head and shoulders better than anything they've made since the P3. Although, I thought the power consumption would be better.aznskickass - Friday, July 14, 2006 - link
Man, some AMD fanboys just can't take defeat with dignity.Really expensive? Top of the line, sure, but funny you fail to mention the E6300 and E6600, which both offer far better value than the equivalent priced A64.
Finally match (or even exceed by a few points)?
OK, here is where I suggest you get your eyes checked out, or go back to school and learn to read graphs. C2D *spanked* A64, not 'match it or exceed it by a little'.
I think you are just upset that AMDs days as performance crown are over. Tough life being a fanboy eh. You gotta take the ups with the downs son. ;)

how is a $999 C2E hundreds of dollars more than a $999 FX-62? How is a 55% increase in performance "match (or even exceed by a few points)"? Perhap a slow reading of the article is need.Genx87 - Friday, July 14, 2006 - link
Intel has a hot chip on their hands here. Problem is, when will it have SLI available?And when will we finally see a review using an Nvidia chipset on the AMD side of this equation?

newegg has started the conroe game by getting a $460 premium on extreme CD2http://www.newegg.com/Product/Product.asp?Item=N82...">http://www.newegg.com/Product/Product.asp?Item=N82...

errr......thats a rape of $360, not $460 - my bad (duh)

It's not on the website anymore. I can't find any Conroe's up their at all. Non-existant. Also, and I know some of you read this but didn't AT say that the supply Conroe would be tight and would drive prices up until the end of the year? So why the bitching about higher prices? If Dell and others are buying up and making supply tight then prices go up. That's the way stuff is.Also, who has a Conroe other than the EE that we can buy today? Also, if these CPU's aren't available and today is the launch day then wouldn't this be considered a paper launch? And one more thing, where are the motherboards for this thing?

technically a paper launch means there were none available at all on launch date. my understsanding is that there were some of these available, they have just been bought up. a limited supply is still better than a true paper launch, imho, even if the end result is the same for most of us - no product available to buy.JarredWalton - Friday, July 14, 2006 - link
This is a paper launch, and there's a variety of political reasons for it. Among the reasons:1 -- AMD is cutting their processor prices in a couple weeks, right after Core 2 Duo was supposed to launch. Intel wanted to launch first.
2 -- People have been previewing Conroe performance for a while, because they got processors without going through Intel. Some were upset that they couldn't do articles because they didn't want to put in the time or effort trying to get a chip through other sources. By moving up the NDA lift date, Intel now allows all of the web sites to talk about Core 2 Duo in the open.
Anyway, it's all a marketing war right now, and both AMD and Intel are guilty. Where are the Energy Efficient AMD processors? In about the same place as current Core 2 Duo chips. Basically, though, Intel is building up supply before the official availability launch as opposed to the NDA launch. We might actually be pleasant surprised by availability at the end of the month.

How can it be a paperlaunch if they haven´t launched yet? Launch is still july 27th.Having sites test an upcoming product is a whole other matter.
And just because some can buy B2 stepping retail Core 2 Duos from sites already shipping them means nothing.
Here is a pic of a retail X6800 btw ;)
