A Plan of Attack
In our E6750 preview we demonstrated that the 1333MHz FSB basically offered no tangible performance improvement over previous 1066MHz chips. That fact, combined with Intel's aggressive pricing of 1333MHz FSB parts helped us do a little cleaning up in today's charts - let's look at the contenders.
Quad Core
The quad core lineup in today's review is straightforward, we've got Intel's four quad-core offerings (including the latest QX6850) and AMD's dual dual-core FX-74 setup:
| CPU | Clock Speed | FSB | L2 Cache | Pricing |
| Intel Core 2 Extreme QX6850 | 3.00GHz | 1333 | 4MBx2 | $999 |
| Intel Core 2 Extreme QX6800 | 2.93GHz | 1066 | 4MBx2 | $999 |
| AMD Athlon 64 FX-74 | 3.0GHz | HT | 1MBx2 | $599/pair |
| Intel Core 2 Quad Q6700 | 2.66GHz | 1066 | 4MBx2 | $530 |
| Intel Core 2 Quad Q6600 | 2.40GHz | 1066 | 4MBx2 | $266 |
Price-wise, the only AMD/Intel competition we have here is between the FX-74 and the Q6700. Do keep in mind that as the FX-74 is a dual-socket configuration, the motherboard is a bit more expensive than what you can use with any of the single-socket quad-core Intel solutions.
And you read right, $266 can get you four amazingly fast cores on a single chip with the Q6600 after July 22nd.
Dual Core
| CPU | Clock Speed | L2 Cache | Pricing |
| Intel Core 2 Duo E6850 | 3.00GHz | 4MB | $266 |
| Intel Core 2 Duo E6750 | 2.66GHz | 4MB | $183 |
| AMD Athlon 64 X2 6000+ | 3.0GHz | 1MBx2 | $178 |
| Intel Core 2 Duo E6550 | 2.33GHz | 4MB | $163 |
| AMD Athlon 64 X2 5600+ | 2.8GHz | 1MBx2 | $157 |
Above $200, AMD has nothing to offer, so the E6850 actually ends up competing with other Intel offerings. Do you go with a dual core E6850 or a quad-core Q6600 for the same $266 price tag? Below $200 we have a couple of interesting matchups: the E6750 vs. the 6000+ and the E6550 vs. the 5600+.
We're working on a lower cost CPU comparison where we'll address the sub-$150 offerings from both camps.
The Laundry List
We're trying to answer the following questions today:
1) Does the 1333MHz FSB have any impact on quad-core performance?
2) Is AMD's Athlon 64 FX-74 competitive with Intel's cheaper Core 2 Quad Q6700?
3) At approximately $180, which is faster: AMD's Athlon 64 X2 6000+ or Intel's Core 2 Duo E6750?
4) At approximately $160, which is faster: AMD's Athlon 64 X2 5600+ or Intel's Core 2 Duo E6550?
5) For $266, should you buy a quad-core Core 2 Quad Q6600 or a dual-core Core 2 Duo E6850?
Let's get to it.

nooo! I just bought an Core 2 Duo E6420 for $186The replacement seems like the E6750 at $183

sorry buddy, but these prices weren't exactly a secret.lennylim - Monday, July 16, 2007 - link
If you go according to max. multiplier, an important number for overclocking, the pricing makes some kind of sense.Looking at dual cores only, here's the pricing by multiplier.
7x multiplier : $163
8x multiplier : $183
9x multiplier : $224 (E6600) / $266 (E6850)
10x multiplier : $316
Still a damn good price for C2D. And the E6600 is actually a good deal for overclockers.

The price of the X2 6000 is $169.99 on Newegg not $180. Even though the new stuff is quicker than AMD's best it's only a little quicker and the $10 difference between them plus the cheaper motherboards for AMD will still pretty much seal the deal for my next upgrade. If the quad cores were $180 then I would be willing to stretch for the extra cost of the Intel motherboards (Intel or Nvidia chipset).MrKaz - Monday, July 16, 2007 - link
Finally someone with brains.I already have said the same with different words.
Did you also notice they only mention the extra price cost on the AMD motherboard because of Quad FX, they don’t mention Intel extra price premium on the motherboard.
The Intel motherboards are very expensive, the ASUS P5N-E SLI for example in my country costs 120€, the AMD version the M2N-E SLI 80€. Its 40€ difference.
Also the only interesting Core 2 Duo is the E6550 which costs $163. Lower than this you get one castrated CPU from Intel.
AMD X2 3600 costs 60€ in my country so its 60+80=140€
Intel E6550 168€ so its 120€+168€=288€
Its “just” 148€ difference or one X1950PRO if you prefer.

Why compare the E6550, which is faster than all but the AMD 6000+ with a 3600+ that is slower than Intel's "castrated" Pentium E2160?

I was looking at the ASUS M2N32-SLI Deluxe which is $170 compared to the ASUS P5N32-SLI Premium for $210 here. A $40 difference that I can use towards my 8800GTS and then add the $10 from the CPU difference and I STILL get a computer that plays BF2 or whatever at WELL over 100fps.Pirks - Monday, July 16, 2007 - link
exactly, this is why I'm going to use AMD for my gaming rig for the foreseeable future. cheap AMD cpu plus expensive nvidia 3D video equals best gaming experience, definitely better than that of intel FOR THE SAME PRICE. AMD is the best friend for the gamer, while Intel is the best friend for media encoder/3D renderer kind of guy, or anyone who loads all their four cores at 100%iceburger - Monday, July 16, 2007 - link
I've had the same reasoning for the last 10 years- AMD platform always cost less- sometimes the difference will cover nice video card. IMHO this Intel price cut may backfire for them- the reason you spend money on marketing is to be able to get higher profit margins. Instead of dropping the price, the reasonable decision would have been to "milk" the market- maintain the current separation: high- and mid-end for Intel, low-end for AMD. This price cut is strictly a hostile move aimed to bury AMD's entire line and force them to lose even more with consecutive AMD price cut. However Intel has higher fixed development cost and even if they sell more CPUs, their profit will be lower- it's a lose-lose situation. Reminds me of GWB's tax cuts.Sunrise089 - Monday, July 16, 2007 - link
Only problem with all of this otherwise sound reasoning is that 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, and that sort of blows the AMD side of the equation out of the water.I'm and AMD fan myself, but you have to admit, anyone who even considers overclocking their CPU has no business picking the AMD side unless they just want to help the underdog.
Pointing out Anandtech's failure to mention the cheaper AMD platform is fair enough, but it was AT LEAST equally damaging to the Intel side to not show benchmarks from an overclocked 6000+ vs a 6850. Does anyone think it would be close?
