Intel Core 2 Duo E4300: Affordable and Highly Overclockable

Encoding Performance
At default clock speeds, the Core 2 Duo E4300 completed our DivX test in the same amount of time as AMD's Athlon 64 X2 5000+. Overclocked, the E4300 has a 11% advantage over the X6800.
Windows Media Encoder is far more favorable to AMD CPUs and thus the E4300 ends up being a little slower than the X2 4200+. Our overclocked chip ends up, once again, on top of the charts.
MP3 encoding performance is quite competitive, with the E4300 offering performance similar to the X2 4600+ and the E6300. Overclocked performance is once again competitive with the X6800.

It would be nice if they would include 64bit benchmarks, even nicer would be 64bit Linux benchmarks since I am not paying $300-400 for Vi$ta.mlambert890 - Wednesday, January 10, 2007 - link
http://www.xbitlabs.com/articles/cpu/display/core2...">http://www.xbitlabs.com/articles/cpu/display/core2...Core 2 performs a few fetch and decode tricks in IA32 that it cant perform in EM64T. People seem to be overdramatizing the presumed effect that these tricks (or lack thereof) would have on 64bit performance. Ive done a lot of testing with C2 in various forms on XP, 2k3 and Vista x64 and have seen no defficiency with real world performance of C2 EM64T. I'm confident that benchmarks will prove this out.

If you're not into overclocking, there are numerous cheap C2D motherboards and unlike the A64, you don't need fast memory. Unlike the A64 which requires DDR2-800 just to perform like S939 DDR-400. And if you overclock, then a simple overclock gives you performance that no AMD can touch.And for Vista, the C2D will out-perform the A64 just like it outperforms the A64 in everything else.

Hello!Could you explain to me if Intel's energy-saving feature still works in idle situations when overclocked or does changing the FSB mean that the CPU is _always_ running at those high speeds?
Can you give me a link to a tutorial how to change FSB speed - or is it simply a matter of mainboard BIOS settings?

I believe EIST won't work with overclocking(someone update me), but C1E works. The lowest speed at C1E will increase proportionally to FSB speeds though.
Changing FSB speed is done by BIOS. You can do it from Windows too if your mainboard has the software for it.

What is more efficient regarding energy-saving?C1e or EIST?
I really would like to see documented in the article _how_ the CPU was overclocked.

All I can say is... wow... just simply wow...A friend of mine is considering sticking with AMD for building a new budget system. I'll have to show her this to see if this'll change her mind. I've already suggested to her to go where the performance is. I hope she'll change her mind after looking through this quick article.
I so wish I could jump on the Core2 bandwagon right now. I'm glad that Intel is going to put 4MB on all of their 6000 series processors. This'll give me an additional incentive to look at their lowest 4MB Core2 offering. All I'd need then is a good matching motherboard and some quality DDR2 RAM.

This could very well be put at work in a performance microATX board. When a microATX boards review will be here?Macuser89 - Wednesday, January 10, 2007 - link
I would like to see the same benchmarks, but with the x6800 overclocked as far as it can go. with the same cooling as the e4300.
