Intel Core 2 Extreme QX6850 and Massive Price Cutsby Anand Lal Shimpi on July 16, 2007 3:04 AM EST

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.
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.
|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?
