Intel Core 2 Duo E6300 & E6400: Tremendous Value Through Overclocking

Final Words
If it weren't for AMD, we wouldn't have Core 2, and if it weren't for Core 2 then we wouldn't have affordable Athlon 64 X2s. Right now is one of the best times to purchase a new processor that we've seen in a long time -- assuming current prices hold and that availability of Core 2 Duo chips is reasonable in the next week or so. If you've been running a single core processor and are finally looking to make the jump to dual core computing, there's little reason not to at this point.
The processor landscape has been changed once more thanks to AMD's extremely aggressive price cuts. The Core 2 Duo E6300 is a better performer than the X2 3800+ but is also more expensive, thankfully for the E6300's sake it is also faster than the 4200+ and the 4600+ in some benchmarks. Overall the E6300 is a better buy, but at stock speeds the advantage isn't nearly as great as the faster Core 2 parts. In many benchmarks the X2 4200+ isn't that far off the E6300's performance, sometimes even outperforming it at virtually the same price. Overclocking changes everything though, as our 2.592GHz E6300 ended up faster than AMD's FX-62 in almost every single benchmark. If you're not an overclocker, then the Athlon 64 X2 4200+ looks to be a competitive alternative to the Core 2 E6300.
The E6400 finds itself in between the X2 4200+ and X2 4600+ in price, but in performance the E6400 generally lands in between the 4600+ and 5000+. Once again, with these 2MB parts the performance advantage isn't nearly as impressive as with the 4MB parts (partly due to the fact that their native clock speed is lower, in addition to the smaller L2 cache), but even with AMD's new price cuts the Core 2 is still very competitive at worst. If you're not opposed to overclocking, then the E6400 can offer you more than you can get from any currently shipping AMD CPU - our chip managed an effortless 2.88GHz overclock which gave us $1000 CPU performance for $224.
There are two potential concerns with building a budget Core 2 Duo system. The first is availability, and hopefully we will have a clear answer on that subject in the near future. The other is motherboard cost. The ASUS P5W-DH we used in this article is currently the best overclocking motherboard we've seen for the socket 775 platform, but at $250 it is anything but cheap. We have seen quite a few of the P965 motherboards that can also overclock the budget Core 2 chips to reasonable levels, with prices hovering much closer to $140. Unfortunately, none of those boards can support SLI or CrossFire at present.
If you are simply interested in maximum processor performance, P965 with any of the Core 2 Duo parts is going to be very fast. Gamers on the other hand are probably going to at least want to think about SLI/CrossFire, as typical gaming settings will be GPU limited with just about any current single GPU. That means they might need to pay more for an appropriate motherboard, especially if overclocking is a primary concern. We're also waiting to find out how nForce 500 for Intel does in the overclocking arena; at present, there's definitely concerns about whether or not the NVIDIA motherboards can reach the high FSB speeds that are required for overclocking everything but the X6800.
The E6300 and E6400 can easily overclock to E6700 and Core 2 Extreme X6800 levels, though the smaller cache does limit performance a bit. That being said, our overclocked E6300 was able to equal and in all cases but one outperform AMD's Athlon 64 FX-62. In fact, in quite a few benchmarks, the overclocked E6300 is essentially out of reach of anything AMD can offer with their current K8 designs. At $183, the value here is tremendous, and if you're willing to overclock the benefits don't get any clearer than that.

Damn, Intel must have lost my address. ;-)

This is just so sad, how far AMD fanboys will go. I really wish there was moderation allowed, here the user point system is hardly effective enough.JarredWalton - Wednesday, July 26, 2006 - link
I'm pretty sure that was sarcasm, Coldpower. LOL :)coldpower27 - Wednesday, July 26, 2006 - link
Well, I guess my bad, though without a /sarcasm tag it's hard to tell. This is n't real life where you can here the tone of people's voices. :PSunrise089 - Wednesday, July 26, 2006 - link
You were unable to tell "the Magic Money Fairy" was sarcasm?Why not just come clean and admit that you didn't read carefully.
coldpower27 - Wednesday, July 26, 2006 - link
I read plenty carefully, thanks.Sunrise089 - Thursday, July 27, 2006 - link
Seriously?You were seriously unable to tell the following was sarcasm:
"...you all get weekly checks from Intel"
"...most Intel processors really don't even work at all"
"...Intel pays off the companies to say they're Intel Inside"
and of course
"the Magic Money Fairy."?
Dude, it's understandable that you were reading fast and thought the post was fanboy-ism, which there is indeed a lot of. Refusing to admit that and stating instead that the original (actually quite funny) post wasn't clear is insulting to that poster and frankly somewhat alarming.

Your taking this way to seriously, if I can't recognize without smiley faces or a tag that it is sarcasm, it's acceptable considering this is written language. I rely on the tone of the conversation, which is absent here.
There is nothing to admit. There continues to be alot of AMD fanboyism at this site, even reading carefully, it sometimes isn't a simple task to deduce what is sarcasm from the rest of the fanboy drivel.
I am not refusing to admit anything, the poster should have considered this before he made the post, that not everyone will be able to catch the sarcasm, I assume the poster would have thought about this, and I already said my bad in the above post. You may think the establish indicators are sufficient for you, for me they are not.
Not everyone can percieve exactly the same things you can allright, and assuming otherwise is ridiculous in itself.

lol - was a bit of a knee-jerk response, I thought the same thing until I read all the replies before, and then realised that it was indeed (hopefully!) sarcasm. You can't blame coldpower with the amount of rubbish being spouted by some users with how 'biased' this site is.VooDooAddict - Wednesday, July 26, 2006 - link
Nice to see you get your own article again from time to time, reminds me of when I started visiting AT.The following deals with the gaming performance question most people are asking. I understand that the true focus of the article is 2m Cache vs. 4m Cache and the Overclocking impact. E6600 is still at the top of my list for a powerful new SFF thanks to the article. Regardless the article has prompted the following:
(Maybe the following can be highlighted in a Budget/Midrange Gaming system buying guide...)
I think it's undeniably clear that the Core 2 Duo Chips offer the most headroom for future GPUs and should therefore be at the top of most gamers’ lists if they can afford it.
What I think some people may still find important is that with any of these amazing CPUs ... gaming is still GPU limited. It begs for the comparison of the E6300/E6400, the 3800/4200 X2, and 3500/3800 Single Cores. With a quality lower cost boards and single video cards like the 7950GX2 and 1900 XT. Do the lower end CPUs really limit gaming with a single card solution? I think the 7950 would also give a good showing as to if the new higher end and Dual Cores really needed for SLI, or if new new "low end" which used to be the high end are enough to keep that 7950 going. Most gamers I find at LANs still only run 1280x1024 without massive AA/AF simply due to the popularity of the cheep 17" and 19" sub 12ms LCDs. I also find a large number of gamers (who enjoy gaming but don't really spend much time enthusiastic about the hardware) don't ever turn on AA/AF.
I'm not saying you didn't state that most games are still GPU bound. You clearly tell gamers clearly in the article that it's probably best to buy the E6300 with a high-end video card then a E6600 and a mid range video card. I just think that it needs to be shown.
