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

The Test
The performance results in this review are largely the same as those from our earlier Core 2 review. However, there are a few changes to the test configuration that are worth noting:
- The E6300/E6400 were run on the ASUS P5W DH Deluxe as it is a better motherboard for overclocking than the Intel D975X. Performance differences between the Intel and ASUS boards are negligible and thus the results are directly comparable to one another.
- The E6300 numbers in this review are a bit higher than in our last review because we are using a B1 stepping E6300, compared to the A1 stepping E6300 used in our previous article. The A1 CPU we used in the last article was a pre-production chip, while the B1 CPUs we're using here today are production CPUs that offer slightly better performance in some cases. All other Core 2 and Core 2 Extreme CPUs in this article are all B1 or later.
- As we mentioned earlier, we did not have a Socket-AM2 X2 3800+ on hand that we could use for overclocking results, but you can get an idea of what an overclocked X2 3800+ would perform like by looking at the performance results for the X2 4600+, 5000+ and the FX-62. We looked at Athlon 64 X2 3800+ overclocking in the past on socket 939, and we would expect the AM2 chips to overclock similarly.
- We've eliminated all of the Pentium D lineup from the bar graphs except for the Pentium EE 965, which is included as a reference point.

I wonder if motherboard prices fore the Conroe's will go down once Nvidia and ATI start making chipsets for those CPU's.Sunrise089 - Wednesday, July 26, 2006 - link
I'm sure they will, and I will myself switch to Conroe when prices drop enough.For now though, there seem to be many questions left unanswered: how much these chips actually overclock (seems both that low-end parts do not overclock nearly as well as high-end, which is very different from X2s, and it also seems that not everyone is matching AT's overclock results), how expensive of a motherboard you need to get a good overclock (seems like a very expensive one, very different from X2s once again, where a cheap DFI Infinity or ePox motherboard overclocks basically as well as an expensive ASUS), and my above point of whether or not Conroe is actually faster dollar for dollar at the X2 5000+ level and below (I suspect it isn't). These articles need to be adressing these above points, rather than pointing out what we already understand - yes Conroe is faster clock for clock.
Anandtech is doing something very dangerous by putting certain chips together in people's minds. The X2 3800+ and E6300 are NOT competitors, the AMD part is probably $150 cheaper after motherboard purchase. But since AT is placing ideas in people's heads about the Intel part being so much faster, when Conroe is available for purchase and the very possible price-gouging takes place, people are still going to buy them thanks to sloppy reporting, since they are now convinced that Conroe destroys AMD's equivilent chips by such a large degree, and therefore paying $250 for a E6300 must still be a good choice. If AT were instead comparing the E6300 to a X2 5000+, buyers would see the true performance difference, and then be able to figure out that if the Intel part is at all above MSRP it isn't a good deal with these motherboard prices.

Again, where are you getting that? It's an AM2 AMD vs Conroe comparison, so again, you're point about motherboard cost isn't as relevant as you make it out to be. Granted, you'll pay more this week for a Conroe-capable motherboard and the E6300 is still approximately $31 more but it's not the dramatic price gap that would elevate the 5000+ parts to be equivalent.
It would have been nice to see a 939 vs. Conroe comparison, but even that's not apples to apples since the 4800+ is rated at 110w on AMD's site vs. 65w for the Conroes. Personally, sitting in a heatwave I'm beginning to appreciate how much a s939 4000+ throws off.

And check the article again Mr. Attention-to-detail. An E6300 isn't $250, it's $183. Guess you skipped that part once you started foaming at the mouth....Sunrise089 - Wednesday, July 26, 2006 - link
Please read more carefully. I was talking about buying a post price-gouging E6300, and therefore making up a higher price it might go for. I think it was quite clear.theteamaqua - Wednesday, July 26, 2006 - link
meh no where near extremeES5 stepping B1 (retail is stepping6 , B2) can go much higher
E6400 : 8x480
E6300: 7x500
this is weak OCing

Everyone knows AMD processors have always been, and will always be, far superior to the crap from Intel. Any article suggesting otherwise is clear evidence of pro-Intel bias, that indeed you all get weekly checks from Intel for the favorable press. The reality is that most Intel processors really don't even work at all; all the supposed PC's sold with Intel processors secretly use AMD processors instead, but again Intel pays off the companies to say they're Intel Inside. Intel has an endless supply of money because of their unfair business practices and the Magic Money Fairy.johnsonx - Friday, July 28, 2006 - link
hey, also, why did y'all mod me down to zero on that? come on, it was funny! at least a little funny? worth a chuckle for everyone but coldpower?johnsonx - Friday, July 28, 2006 - link
I daresay I got quite a laugh out of coldpower's response(s) to my little attempt at satire.johnsonx - Friday, July 28, 2006 - link
by the way, coldpower, I didn't include the silly /sarcasm tag because I thought it would be far less funny (just plain stupid even) if I did. The idea was to start off sounding rather fanboy-ish but potentially serious, head towards the deep-end, and then go completely into tin-foil-hat territory. I was actually going to make it far longer and more complicated, probably tie in to the Masons somehow, but I had other things to do so I just wound it up quick with the 'Magic Money Fairy' bit.Surely I thought anyone I got on the hook would have wiggled off around the time I claimed that most 'Intel-Inside' PC's actually had AMD chips in them...
