so I have a bastard child Conroe that flunked Cache school..

Well I just checked my Bank Account info.. and my pay went in today.. hmm let me seeeeeee newegg..tigerdirect... make sure the wife isnt watching (She is kinda upset still about this $300 upgrade going closer to $1500 right before Christmas..)

hmm an X6800 hmmm comes with a free MP3 player.. think if I gave her the MP3 Player it would stave off a divorce?

prolly not.. and I cant afford to upgrade HER! she is #4.. and I still owe for the first 3!

The 2MB more of cache helps by about 3-5% in mostly desktop applications. The reason you see SuperPI jumps is because the program can run INSIDE the L2 cache much easier. For the same reason DDR2 runs SuperPI better the higher the bandwidth. SuperPI runs better with high mhz RAM and big L2. SuperPI is by no means a good indicator for real world performance. It's a 100% synthetic benchmark that is easily manipulated to yield high results.

ckp64 is correct. The allendales ARE conroes with disabled cache. The allendales are also more overclockable than the conroes. People seem to think that the Conroe core is better at overclocking. Let me put this into perspective. What's easier, running a 6300 at 3.3ghz stable or running a conroe at 3.9ghz stable?

6300 stock = 1.8
6600 stock - 2.4

6300 at 3.3 = 1.5ghz oc. 6600 at 3.9 = 1.5ghz oc.

There you have it.

benchmarks show that 2mb extra cache doesnt make that much of a difference since 2mb in windows XP already is alot. It would basicly be the same as running 2gb over 4gb in windows. 4gb you may find faster at some times but you really only need 2gb and its not noticable enough. At this point right now I say that the E6300 and E6400 are perfectly fine and compete with the 6600 very well. You could go either way and wouldnt notce that much of an increase in speeds.
Yet later on when vista is out then i think we will start seeing more and more of a difference from 2mb opposed to 4mb. Even then though 2mb will still be enough. If I actully had another 140 bucks to blow I would have gotten the E6600 but i was on a budget so I got the E6300.

In your case I suggest you dont worry about it and keep your E6400 untill Q3 of 07 when the new intel's and amd's will be out. So just save that 320 bucks and use it later on an awesome Intel or AMD chip later (whichever is the best in the next gen).

You are going to have to, have to I said, show a proof of such claim. Two times it has been said but no a link that it proofs it.

And last time I checked, the micro-code name for the E6300 and 6400 were and are Allendale.

And AFAIK, I haven't heard nor red anything about cache being disabled.



I think that by overclocking an E6300 or E6400 300mhz+ than an E6600, it compensates for the less cache. Something like a 3.0ghz Conroe to 3.30ghz to Allendale.

You'll find plenty of sources that will tell you the code name for these 2MB Core 2 Duo processors is "Allendale," but Intel says otherwise. These CPUs are still code-named "Conroe," which makes sense since they're the same physical chips with half of their L2 cache disabled. Intel may well be cooking up a chip code-named Allendale with 2MB of L2 cache natively, but this is not that chip.

Allendale (E4300):


These pics show the difference between a Conroe and TRUE Allendale (E4300).

Also, why does Intel only provide ONE data sheet, for ALL of the E6700, E6600, E6400, E6300? See here.
IF they were different core types, wouldn't you think that Intel would provide us with a E6700/E6600 data sheet and a E6400/E6300 data sheet?

Anandtech tested the difference between 2MB and 4MB cache.

http://www.anandtech.com/cpuchipsets...spx?i=2795&p=4

It's about 3.5%. For games it doesn't even excede 2%. So that's a 2fps gain when your game runs 100 fps...

I beleive that if you are trying to Save money , you should stick with the E6300 or E6400. These are quite overclockable and with the E6600 , you can aquire higher speeds , but it will cost you 300 + , and thats without the after market cooling. Technology is always changing.
