Pen D 930/940/950 vs. Core 2 Duo E6400

[halutzparilla]

either way its still quite expensive...

so you mean to say i have to cut down in other hardware and invest on the cpu

well you see, i really would like to have C2D but the budget is really in question...

specially with my wife... (so guys if you want to be able to buy things you want don't get married yet...)

anyway i'll stick to P D 930 or 945, until the C2D drops prize...

Core 2 Duo spanks all previous Pentium D. It also appears they OC well.

To put things into perspective for you: An E6600 outpaces FX62 in just about every benchmark. There's no doubt in my mind that any Allendale(E6300 or E6400) can be overclocked fairly easily past E6600 speeds.

E6300\E6400 have 2mb of cache while E6600, E6700, and X6800 EE have 4mb cache. The average performance gain from the extra chache yields anywhere from 0-10% performance increase over 2mb.

Stay tuned as I have an E6400 on it's way to me, I ordered it a couple hours ago. E6400 is also instock at ZZF.

How much do you think E6400 Allendale can be OC'd?

I wish I could tell you with certaintiy. With aftermarket air cooling, I would estimate to around 2.66ghz with no voltage increase. It could go higher. That is a 500mhz OC. Sit tight and in a few days I will have my results posted here so you can see first hand..

okay... but i saw this while i'm browsing the net...
"""Our E6400 was a bit more successful, reaching 2.88GHz using a 360MHz FSB at 1.350V (up from 1.300V stock):"""

probably it can really reach 3.0ghz and have the great stability...

Be carefull those are B1 stepping Engineer Samples. Retail Core 2 Duo are coming out in step B2, so retail will be revised and improved.

I personally think E6400 will be able to do 3.0ghz, and if I was you, I would pull the trigger on one ASAP!

I'm watercooling mine and plan on running 3.2ghz 24/7.

i'll give it a thought since i won't be able to move a penny until my financial crisis for august gets uplifted, then i can start the time to do the list of good and probablly worth it hardware...

well after getting tossed about the benchmark ring like a joint at a bob marley concert intel finally said enough is enough and began to search for a new architecture. they purchased an isreali company and asked them to make an enerygy efficient processor that was powerful but had a low power requirement for their moble department. this company set about this project by heavily modifying the pentium 3 core into what eventually became known at the pentium m. development continued into the core duo line of mobile processors. they ran cool and performed admirably.

these processors proved to be a godsend for intel who got the bright idea to modify them into what is now known as core 2 duo. while they have lower clock frequencies, they perform many more instructions per cycle when compared to the older netburst line of processors. in fact the lowly E6400 has performance on par with AMD's vuanted FX 62 and the performance only increases with higher model number.

overclocking the core 2 duo has been rather successfull too. in fact reaching 3+ ghz with a core 2 duo is not a far off idea.

if you have the choice between any of the above listed processors, go with the core 2 duo. it runs VERY cool and has performance to boot.

*correction: it was an isreali firm*

I haven't read the entire thread, but I believe it comes down to the number of instructions being executed per clock. With the Conroe at least that number has been increased 4 times. I believe from 3 to 12? Someone can correct me if If I'm wrong. That is why you can get such a bigger bang for less MHZ>

With a Core 2 Duo, you can do this on air.

I have a 920 arriving in the mail in the next few days. I'm expecting to get it around 3.5ghz on this motherboard. So I'll post the super pi from it here. It won't come anywhere close I am sure. But it will be a good comparison for the original thread question.

There is also a review on here somewhere of the 920 and 930. You can compare those numbers to the ones above and that will show it clearly.
