Affordable Quad Core: AMD Athlon 64 FX-74 vs. Intel Core 2 Quad Q6700
AMD doesn't have any quad-core CPUs on the market today, but you can get four cores in a single motherboard by going with a Quad FX platform. AMD's attempt at building a enthusiast class dual socket, dual core platform is far from the most elegant solution in the world, but it does provide an interesting upgrade path. The Quad FX platform uses Socket-1207 CPUs and will be able to be upgraded to dual quad-core chips when they are available, giving you eight cores on a desktop motherboard. Intel has a similar offering called V8, but the AMD Quad FX platform uses standard desktop DDR2 memory which makes it infinitely more attractive.
The problem with Quad FX is that the motherboard is expensive, the whole platform consumes a great deal of power, and you can just as easily get a single socket, quad-core solution from Intel for less money. We haven't revisited Quad FX vs. Quad-Core since AMD introduced the platform, and since then there have been some price cuts on both sides of the fence. AMD now sells two Socket-1207 Athlon 64 FX-74 processors (3.0GHz) at $599 for the pair, making it quite cost competitive with Intel's Core 2 Quad Q6700 ($530).
If we forget about the added cost of a Quad FX motherboard for the moment, how do the two similarly priced processors stack up? The chart below shows the performance advantage/disadvantage the Q6700 holds compared to the FX-74:
That's not very pretty for AMD. The Athlon 64 FX-74 ends up being 1.1% faster in Cinebench but on average, the Q6700 is 14.1% faster than the more expensive Quad FX platform. The only benefit you get with Quad FX is the ability to eventually upgrade it to eight cores, but in our opinion for the majority of users the upgrade path is simply not enough to justify the means to get there.
Taking advantage of four cores on the desktop is tough enough today, and if you really need 8 cores today buying a platform that will support it in the future isn't going to help make your applications faster now. The market for Quad FX continues to be limited and our original recommendation from the first Quad FX review stands: you're better off with Intel's quad-core.

I don’t know but I have very doubts that someone who buys some premium and highest end CPUs will even bother in OC.If I was going to buy one AMD CPU for OC I would choose one of the single core or one dual up to the X4400+, higher than that I was shooting myself in the foot.
With Intel I would go for one of the lowest FSB versions (800/1066) or the slowest of the 1333Mhz (but I doubt I would go for one of this). Going for the 3.0Ghz Intel versions I was again shooting myself in the foot. Why OC something that is already so fast and already in its limits.

VERY far from truth - I'm kind of enthusiast myself, but I specialize in silent & inexpensive gaming computers, and AMD gear is VERY solid choice here, I pick old single core AMDs for nothing on ebay, like $45 for a fast gaming San Diego 4000+, pick older 7900GTX cards on ebay as well for cheap (only the ones I know are silent 'cause reviewers say so) and then I stuff it all in Antec P182, do some other voodoo with Cooler Master or ThermalRight gear... voila, a SILENT gaming rig, chews through S.T.A.L.K.E.R. just like that! and cheap, compared to some intel rigs from overclocking Intel freaks - it is DIRT cheap, cause there are no water, no overheating from fashionable overclocked quad-core intel shit, nothing like that.so you are TOTALLY wrong when you classify all enthusiasts as overclocking intel freaks - there are a lot of us who specialize in silent & inexpensive PCs, including gaming ones. it's easy to pay intel $$$ $$$ $$$ and get watercooled quad extreme blah blah blah, or get a cheap and noisy overclocked aircooled rig. but to get 1) gaming 2) silent 3) cheap PC - this is REAL ART, btw it's not covered at anandtech at all

A User said:"the same folks who are enough of an enthusiast to know that the AMD MB's can save them a bit, and then apply that savings towards either the GPU or grabbing a higher-end AMD processor are very likely to overclock."

Very far from the truth? Possibly for you specifically but he was generalizing and I believe he is correct. People who do care enough and are being specific, building their own PC's tend to be the same people who tinker, and OC their computers. People intrigued enough to read this whole article and pay attention to the benchmarks are more likely to overclock then not.
So to say that it's "VERY far from the truth" is not only incorrect, but ignorant. It's just more fanboys spouting propaganda for their favorite company.
I don't have a preference personally. I buy what the best is for my money, at the time. If it's AMD, then I buy them, if it's intel, then them. I suggest everyone do the same. I've purchased 6 intel chips and 7 amd chips in my life. Most of my intel chips were 286's 386's or pentium 1-2's. Lately I was buying AMD cause they were the better buy, but not now. For the money, I get alot more with intel. I have noticed an increase in reliability as well, after switching to intel.
I may have to take that into consideration on my next chip purchase which (if the wife allows me) will hopefully be soon. :)
Oh and I noticed that some people mentioned that the price cuts would be bad for intel as far as profits go etc... The price cuts benifit us, and thats what matters. I don't care if amd/intel's revenue is down this year by 100% and neither should you. What matters is that we get a good price and a good cpu. If someone brings that up, it just further proves they are fanboys and care more for that particular company then they probably should. Again, getting a decent price is what should matter, not profit margins of a huge company.

please learn to tell the difference between "most likely" and "all"Pirks - Tuesday, July 17, 2007 - link
doesn't matter if you classify all enthusiasts as OC guys, or just "most of them" as OC guys - this is still your subjective opinion, you have no facts to prove it.I classify "most of enthusiasts" as silent PC guys, not OC guys, so what? here ya go, my subjective opinion versus yours. enjoy your meal :P
yeah, and when you get some solid arguments besides your opinion - don't forget to post them here, I'm interested! maybe I'm wrong about most of us being silent PC people, who knows ;)

Well, silence enthusiasts would be better off with Intel seeing as how most of their Core based dual-core lineup now uses less power under load than the 4000+ San Diego, and with the G0 stepping Intel has only increased its performance/watt.
Pirks - Wednesday, July 18, 2007 - link
nice shot, but, alas, a miss - you have no idea how much AMD 65nm and 35watt dualcore chips consume under load. get back to school, read you hardware docs, come back - we'll talk again. good luck ;)Accord99 - Wednesday, July 18, 2007 - link

Pirks - Wednesday, July 18, 2007 - link
you're right about consumption, intel is slightly ahead, but if we take prices and upgrade scenarios (like copious amount of old DDR RAM in the system) into account, the picture is not so rosy for IntelAccord99 - Wednesday, July 18, 2007 - link
In the same way that AMD's K8 was slightly ahead of Prescott.
How so? There aren't any of the low-voltage or 65nm X2s on Socket 939, they're all high-power 90nm models where even the lowly 3800+ uses as much power under load as the fastest dual-core C2D. Meanwhile there are a few DDR1 MB that support C2D if you want, and with the excellent power usage of the C2D, passive cooling is a piece of cake with a half-decent tower heatsink.
