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

Gaming Performance using F.E.A.R. & Rise of Legends
Our F.E.A.R. test should be fairly familiar by now, as it is the built in performance test included with the game. Computer settings were left at "Maximum" while the graphics settings were set to "High" with the resolution cranked up to 1600 x 1200. F.E.A.R. ends up still being more GPU than CPU bound at these settings, even with a pair of X1900 XTs at its disposal, but we do see some separation among the processors:
We mentioned that F.E.A.R. is more GPU limited than many other titles, but without antialiasing enabled the spread is still 42%. As with many other games, the Core 2 Duo chips outperformed their AMD counterparts in terms of price/performance. However, it's questionable how many people would purchase a $200 CPU to pair up with over $1200 worth of motherboard and graphics cards. That doesn't mean the Core 2 Duo isn't faster, but you will certainly need a very powerful graphics chip in order to realize the potential. On the flip side, the extremely strong performance of an overclocked E6300/E6400 means you can spent more money on your graphics setup if you're a gamer and get close enough to the speed of a X6800 through overclocking to drive those high end GPUs.
Rise of Legends is a newcomer to our game benchmark suite and what an excellent addition it is. This Real Time Strategy game looks very good and plays well too; it serves as good filler until the next Command & Conquer title eventually arrives for those looking for an RTS fix. We ran with the resolution set to 1600 x 1200 and the graphics settings set to the medium defaults. We recorded a custom demo of a 3 vs. 2 multiplayer battle and played it back at 4x speed, recording the average frame rate for 10 minutes of the battle. The 10 minutes we focused on contained a good mix of light skirmishes between opponents, base/resource management with very few characters on the screen and of course some very large scale battles. As with most RTSes, Rise of Legends is extremely CPU bound. The performance variability between runs was fairly high in this test, mainly because of how disk intensive the playback can get. Differences in performance of up to 5% should be ignored.
Rise of Legends is clearly a game that demands a lot from the processor, and the additional cache in the 4MB Core 2 Duo chips also appears to have more of an impact in this game than in other games. The only Core 2 chip that AMD's FX-62 is able to beat is the "budget" E6300. If other RTS games perform similarly, strategy gamers will definitely want to upgrade to Core 2. Once again we see that overclocking the E6300 and E6400 get you fairly close to the higher end E6700 and X6800 Core 2 processors; with performance like this, why bother spending any more on a faster Core 2 CPU?

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.
