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

Overclocking
Overclocking lower end CPUs is always more fun if you're actually buying these things because, as long as the manufacturing process is mature and your component selection is sound, you're usually able to reach much higher speeds than you paid for - an ever rewarding achievement. The Athlon 64 X2 CPUs have been fairly good overclockers, with the X2 3800+ usually able to run anywhere from 4600+ speeds (2.4GHz) up to FX-62 speeds (2.8GHz) and sometimes slightly beyond (3.0 - 3.1GHz). While we don't have any Socket-AM2 Athlon 64 X2 3800+ CPUs on hand (we will use a 4600+ and underclock it for our benchmarks), we do have performance results of the X2 4200+, 4600+ and FX-62 to give you an idea of where an overclocked X2 3800+ can get you performance-wise.
What we didn't know previously however was how far we could overclock retail E6300/E6400 CPUs, and furthermore we had no idea what a highly overclocked 2MB Core 2 Duo CPU would perform like. Armed with two B1 stepping Core 2 Duo CPUs, one E6300 and one E6400, we went to task on overclocking them. Our goal wasn't to reach the absolute highest overclocks using high end cooling, but rather the maximum stable overclocks easily attainable with a stock Intel heatsink/fan. Undoubtedly we could have reached higher frequencies with more elaborate cooling, but we were more interested in the bare minimum of what was attainable - and we weren't disappointed.
Our E6300 was able to reach 2.592GHz using a 370MHz FSB at 1.400V (up from 1.320V stock):
Our E6400 was a bit more successful, reaching 2.88GHz using a 360MHz FSB at 1.350V (up from 1.300V stock):
Both CPUs were totally stable when overclocked and were able to complete our multiple days of benchmarking without behaving any less stable than when clocked at their default frequencies.

That's exactly my freaking point.These prices, while listed on their respective manufacturers sites, are not correct. They are two different pricing schemes. One is using the price at which Intel sells them to distributors, the other is not using any pricing scheme that I've ever seen before, except on this site.
I have varifiable proof(read: I know for an ABSOLUTE FACT) that the AMD prices are too high. How do I know this? Because my distributor prices are lower than what is listed in this article. Ergo, the prices listed CANNOT be the prices at which AMD sells to distributors.
Thus, you're using two different pricing scales, making any conclusions based on pricing completely bogus.
Here are accurate pricings(I'll list my price as well as listed MANUFACTURER Suggested Retail Price):
Athlon64 X2 3800+ - $149.00 - MSRP: $186.25
Athlon64 X2 4200+ - 183.00 - 228.75
Athlon64 X2 4600+ - 235.00 - 293.75
Athlon64 X2 5000+ - 294.74 - 368.75
Athlon64 FX-60/62 - 811.00 - 973.95
Core 2 Duo E6300 - 199.58 - 229.95
Core 2 Duo E6300 BTX - 209.05 - 229.95
Core 2 Duo E6400 - 239.58 - 272.95
Core 2 Duo E6600 - 334.32 - 379.95
Core 2 Duo E6700 - 553.26 - 629.95
Core 2 Duo X6800 - 1021.68 - 1164.95
Now, regardless of which pricing you use(distributor pricing, which is based off of manufacturer pricing, or MSRP), the pairings in the article are ALL incorrect. I tell everyone who asks to take these kinds of articles with a grain of salt.

That's not good enough, your word isn't a verifiable item. So that is what needs to be taken with a grain of salt.
It's has to be publicly available information on the web avialable from AMD and Intel, which it is as the AMD pricing charts are avaialble at AMD's site. The Intel numbers correlate directly to Intels' 1000 Unit Quantity chart.
The pricing chart listed for you is only worthwhile for you.
As well the current pricing scheme you posted correlates quite well to which processor vs which processor.
I am using the pricing scales using available information, the pricing scales you have been using aren't publically available so they can't be used. The results used in this article are jsut fine.
The problem with the information you posted is this is the first time I have seen numbers like that and it wasn't available to all.
The MSRP's you quoted while higher then the ones listed in the article paint approximately the same picture.
4200+ vs E6300
4600+ vs E6400
5000+ vs E6600
Your prices will not be use, as they are different from everything else we have seen so far.
The numbers in the article are apples to apples as they are both what is available to the public by both corporations.

That is EXACTLY what I said. Do you even read things before you reply to them?
The Intel pricing is using Intel's price to distributors. The AMD pricing is not using any pricing that is available in any chart or anywhere else.
Hence: the Intel pricing is too low and the AMD pricing is too high...thus forcing processor comparisons that do not actually exist.
And, no, my pricing is not only available to me. It's available to any company that uses distributors, because the pricing is the same, within a few dollars, between all of my distributors. Regionally, every company generally uses the same distributors. Thus, the pricing available from distributors is extremely relevant, despite the fact that you would like it to be otherwise.

Erm... pulling the two (closest) price points out from ZZF:A64 X2 4600+
Anand: $240
ZZF: $260
Delta = $20
E6400
Anand: $224
ZZF: $239
Delta = $15
*****
A64 X2 3800+ (Really should be the 4200+, since it's closer to the E6300 in price, but ZZF has majorly overinflated prices for that chip for some reason.)
Anand: $152
ZZF: $154
Delta = $2
E6300
Anand: $183
ZZF: $199
Delta = $16
In one case, the delta between the two is $5 in Intel's favor, and in the other (not quite matched up price point) it's $14 in AMD's.
Going by ZZF, it would seem that the point you're trying to make doesn't seem to be based in fact.

The prices are completely accurate as they are MSRP's. You want "real world" pricing, this fluctuates based on supply and demand, and is pointless to report as it constantly changes.If AMD wanted they could have listed their "OEM Distributer" pricing on their website, but they don't so we go by what they have listed there. If you want, you can complain to AMD about not listing the distributer pricing on their site.

Like I said if your talking about prices at online retailers it will be a different story, I already discussed this part. Those reamin to be seen.bob661 - Wednesday, July 26, 2006 - link
The AMD prices are a tad higher than listed at ZZF and Monarch. We'll have no way of knowing Intel pricing until the chips are released. I heard it got pushed back to 8/7.coldpower27 - Wednesday, July 26, 2006 - link
Yeah judging by what we have seen so far, no online store has decreased below AMD's retail pricing on their website for the time being. Let alone the OEM distributer prices reported by Dailytech earlier before.gmallen - Wednesday, July 26, 2006 - link
For AMD owners, the true cost of using Conroe includes a new motherboard. I can upgrade to the 5000+ with my current board. So, for me, the AMD solution is much cheaper.krisia2006 - Wednesday, July 26, 2006 - link
The AM2 AMD cpus in the review also require a new mobo/platform for many AMD owners, no?
