Kentsfield is based on Intel’s Core 2 architecture. Some of the architecture’s characteristics are that that all processors are based on a 65nm process, the FSB is at 1066 MHz, and the processors have a shared secondary memory cache of 2 or 4 Mbytes on a single die. An L2 cache of 2Mbytes is used for Intel’s lower end models while the higher end processors usually come with 4 Mbytes.

Externally, Kentsfield looks exactly the same as other Core 2 Duo CPUs. It also uses the same LGA 775 socket. As we have said before, it is important to remember that the Core 2 Extreme QX6700 has 2 separate die on the same processor. Each die contains 2 cores and has 4Mbytes of L2 cache each adding up to a total of 8 Mbytes. The large cache, no doubt, will help capture the heart of enthusiasts.

The only main difference that can be seen between the two processors is the filter caps. These can only be seen when looking at the bottom side of the chip.

In the above screenshot of CPU-Z, we can see that the FSB is 1066.7 MHz. This is identical to all other Core 2 solutions from Intel. L1 data and instruction cache are independent and designated for each core.

Intel has certified their 975X and 965 chipset for use with the Intel QX6700. NVIDIA and ATI have also certified a couple of their chipsets to be compatible with the QX6700. Even though certain solutions have been certified, it is still essential to check whether your specific motherboard is compatible with Quad-core processors. We advise to always check on the manufacturer’s website whether the motherboard is certified or not.
