Intel Quad

The Q6600 is a 2.4GHz chip, like its little brother the E6600. Both CPUs are nearly identical and use the same die(s), except that the Q6600 has two of them. Essentially, everything is doubled. Twice the cores, twice the cache and twice the drool. Like the other Core 2 Duos, Core 2 Quads are based on a 65nm process, although the process requires a slightly higher stock voltage. Since both the Quads are so similar to the Duos, it's no surprise to see that the die size is simply doubled as well, resulting in 2 x 143mm^2.

When compared to the top of the line QX6700 chip, the specs are again identical except for the 2.66GHz clock speed. Other than that, the CPUs are the same, just binned differently. When comparing to the top end Core 2 Duo, the differences are a lot more meaningful. While the QX6700 retails for just under $1,000, so does the X6800. However, when considering the QX6700, you receive a lower clock speed in return for twice the cores. At that point, it's up to you whether you want or need the sheer clock speed or greater benefits for your multi-thread applications.To help put everything into perspective, here's a simple graph showcasing all of Intel's current Core 2 offerings.CPU Model.
