First, L3 cache of the upcoming Intel processors works at full CPU frequency, which means that it will work faster if the CPU clock speed increases.

Anandtech writes:

The CPU operates on a multiplier of the QPI source clock, which in this case is 133MHz. The top bin Nehalem runs at 3.2GHz or 133MHz x 24. The L3 cache and memory controller operate on a separate clock frequency called the un-core clock. This frequency is currently 20x the BCLK, or 2.66GHz.
