The memory bandwidth performance of the Core i7-3770K is similar to that of the i7-2600K, in fact the slight increase in performance can likely be attributed to the 100MHz bump in clock frequency.

Although the memory bandwidth wasn’t improved greatly compared to the Core i7-2600K, the L2 cache performance does. The write performance in particular was much faster when using the Core i7-3770K.
