E6600 or E6400?

post #1 of 33
Thread Starter 
Ok, hopefully my dad will give me the rest of my money from graduation soon(long story..don't ask ) And the time to build my conroe will be at hand. So, I'm at odds between 2 different processors, and the board I've already gotten picked out (AW9D MAX; I have faith in Abit.) Basically i'm wondering which cpu is better for overclocking, the E6400, or the E6600.

Thanks,

I'd get the E6400.

The models with 2mb of L2 cache have been getting 80% overclocks on air.

I'd have to lean towards the E6600. Between having a higher multi and having double teh L2 cache available, it's a winner all 'round. remember, that L2 on the Conroe isn't per core... the 4MB L2 on the E6600 can be available entirely to one core or the other, depending on what is needed... and that's potentially a MAJOR increase in processing speed/power.

But what about FSB. Wouldn't that limit performance somewhat?

I'm leaning towards the e6600 as well...I'm just worried I'll get one of those cores that limit itself at 3.3 or something.

I've run my Conroe CPU with a 450fsb x7 for a 3.15ghz and now I'm runing it at 333fsb x9 and the difference in performance is......well not noticeable at all.

The only part where I can see the difference is in Super PI 1.5xs whic was a second or less than a second slower but otherwise is pretty much the same, at least from what I can see.

But I know there's a big difference between Allendale and Conroe when overclocked, Conroe always wins of course. Is it worth it? Every penny of it.

I agree with nasgul, the 6600 is a sweet cpu, IMO very worth every penny too. It seems faster to me than my 6400. They're both really fast, but I just like the 6600 more. I also agree about the fsb with you, it does help performance some, but it's not nearly the whole shibang, and won't make a 6400 the better cpu at the same clock. And you're right about once OC'd too, my 6600 at 3.6ghz is so fast it blows my mind. I can hit 3.6ghz with the 6400 too, but it's just not quite the same as my 6600, unless you're just clicking around or doing little stuff, but dang my p4 prescott is even quick for the little stuff. I like the 6600 cause it's gotta big brain , and it will be faster for things like video encoding or other intensive tasks.

You will get the 6400 to higher fsb's, maybe even clock it a little higher, but the 6600 will still be faster (for many things). If you want the 4mb cache and high fsb's, get a mobo that can lower multis and pump up the fsb on the 6600 some more . I know it depends on what you're doing on you're pc, but for alot of things the 6600 is faster, even at slower clocks than 6400. The 4mb cache is deffinitely more futureproof as well, if that matters to you, and eventually it will help performance more than now. I don't wanna shoot down the 6400 though, like I said it's quick too, not far behind the 6600 really, and at it's price I can't begin to call it a bad buy. It's an awesome cpu too.

Well, would it make a difference in gaming, since that's what I do a majority of the time?

Maybe to some extent, depends on you're poison. Some games ya, some no. Eventually (maybe sooner than later) it will be more of the ya, and less of the no. As of right now either cpu will smoke in gaming, and will for some time. Gaming is way more dependent on your gpu than you're cpu. I can tell you that neither of these superfast cpu's will even be close to you're gaming bottleneck, it'll be your vid card.

--you're right sdumper, benchies don't mean everything. And ya you won't really feel the difference probably for gaming (yet). You're gpu will hit the performance wall before any of the allendale/conroe cpu's.

In benchmarks but I doubt you will see or feel the difference. My e6400 is no where close to my e6700 in benches but it feels just as fast to me with most things...im talking stock air not extreme cooling...

That said I am selling my P5B deluxe, e6400 and Zalman fan in order to purchase an e6600. So my choice/prefference is pretty clear

Ok, I switched the e6400 on my wishlist to a e6600..so I guess when I get my grad money, I'll be buying it

thanks guys.
