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.

Xbitlabs has a great E6300 review:http://www.xbitlabs.com/articles/cpu/display/core2...">http://www.xbitlabs.com/articles/cpu/display/core2...
Overclocking was limited by a motherboard, but they still managed to achieve 2.94GHz with 420MHz FSB, not bad from a <$200 chip. E6300@2.94GHz was way faster than Athlon64X2@3GHz.

Loved the title, and loved the article. Can't wait till the Return of the Jedi...JackPack - Friday, July 14, 2006 - link

Yeah, but the Emperor WAS overthrown. :)Anyways, good job on the review. Intel is definitely trying to almost GIVE those PD cpu's away it seems. $93? Not that I don't blame them. They would almost HAVE to give them away to get rid of them.

Page 18:According to the prices on page 2, the price for the 2.4GHz E6600 is $316, while the 2.13Ghz E6400 costs $224.

I quote:"The 2.4GHz E6600, which outperformed the FX-62 in most benchmarks at stock speed costs $223, and overclocked to 4Ghz with excellent air cooling"
It costs $316 according to Intel charts. Please fix it.

I was like skimming throught the article and thinking to myself wow. Then I went back and looked at the benchmarks and realized that until I see benchmarks with a wider range of video card and cpus I will reserve my excitement. At the moment my $120.00 used 3200 venice running at 2600MHZ with an X1800XL gives me some very good performance.JarredWalton - Friday, July 14, 2006 - link
I http://www.anandtech.com/guides/showdoc.aspx?i=279...">looked at performance with several CPUs using a 7600 GT (slower than X1800XL, but not by a huge amount). Basically, on lower end GPUs you will be GPU limited and just about any fast CPU. Maybe not always with NetBurst, but K8 and Core2 will be more than sufficient for all but multi-GPU setups (until next gen GPUs arrive).
