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

3D Rendering Performance using 3dsmax 7 & CineBench 9.5
We're looking at 3D rendering performance using two different applications: 3D Studio Max and Cinebench 9.5. Cinebench is a free performance testing utility based off of the CINEMA 4D R8 rendering package. Our scores from 3D Studio Max are a composite score from four rendering tests: CBalls2, SinglePipe2, UnderWater, and 3dsmax5 Rays.
3D rendering relies almost entirely on CPU performance, and cache sizes have very little impact. The end result is that our overclocked E6300 and E6400 place very near the top of the charts, and the overclocked E6400 actually manages to take the lead over the X6800 in the Cinebench multi-CPU rendering test. Clock for clock, Core 2 Duo holds about a 9-11% performance advantage in 3D rendering over the AMD X2 processors. The difference between the fastest and slowest systems tested here is roughly 60%-70%, and due to the time-consuming nature of 3D rendering even small performance increases are very welcome.
Once again we see that while the Core 2 Duo E6300 is slightly faster than the Athlon 64 X2 4200+, and once overclocked it's out of reach of even an FX-62. The E6400 is also an impressive little chip, offering performance around the X2 4600+ and X2 5000+ levels.

Read the entire post and see what the outcome is before posting this kind of information.

That's the reason why he was using stepping 5 cores, if he would have used stepping 6, no article, no clicks, no advertising money (from Intel(?) ;-) )
I mean an overclocking article itself is nonsense, exspecially if you only have 1 kind of a specific CPU and that one is directly from Intel...
Just wait until the first guys bought E6300s because of anandtech and then stuck around ~2.0/2.2 GHz. Guess who is angry then ...
Sadly but it looks like anandtech does not care too much about that :(

The retail chips are overclocking just as well as the ES chips from all indications the past few days. I know my retail E6400 is 150MHz higher than the ES sample. ;-) Here is an example at XS.......

As soon as we can get our hands on something other than B1 stepping CPUs we'll include those results. As far as I know, there's nothing that has been changed in current silicon revisions to severely limit overclocking. I haven't run into the issues myself but I will do my best to follow up once I can get later silicon.Take care,
Anand

Thanks Anand,I don’t know if this is true any more but I seem to recall that Intel has a small scale FAB just for engineering samples, and I think that they tend to use it both as a test to validate the new FAB process as well as the CPU design. Thus the engineering samples tend to be better then the mass production chips. Remember the 5 GHz Prescott Intel showed off. I don’t think that anyone go a 5 GHz Prescott running from production chips without having to use liquid nitrogen to keep the chip cool.
This is something to keep in mind when benching the ES ability. The real production chip might be totally different from a thermal and OC aspect.

its been reported that there is one change in b2 retail stepping .based on 3 6800 retail versions (b2) @ (xs) b1 stepping seem to oc better than the retail versions
so right now it seems to early to prejudge ..

Anand, your X2 4200+ $215 is wrong. It's EE version. Normal version is $187http://www.amd.com/us-en/Processors/ProductInforma...">http://www.amd.com/us-en/Processors/Pro...ion/0,,3...

Get a better mobo AT and you'll see what the E6300 can really do. The $150 Gigabyte DS3 goes well over 400 FSB with the right RAM.goinginstyle - Thursday, July 27, 2006 - link
His motherboard is fine, using stock cooling is what limited the overclocks.rjm55 - Wednesday, July 26, 2006 - link
It's been interesting to watch as AT has paid more and more attention to overclocking. Fortunately for me, the overclocking on good air cooling has been a perfect match for what I'm looking for. I just checked and the monster Tuniq cooler we saw in the Conroe launch sells for just $49. People using it say it is silent because of the huge fan that turns slow inside the core. The point is I can likely go even further with the Tuniq than Anand found here - which was impressive enough.Now that we see the headroom on even the cheapest Conroe CPUs it is hard to understnad why anyone can consider an AM2 for anything but the low-end. Until Am2 drops to 65nm the Conroe OC blows away anything I can do with my AM2 chip.
Thanks for showing us what great overclockers Conroe is turning out to be! The E6600 with 4MB cache for $312 is looking mighty sweet for me. If I remeber you got yours to 4GHz.
