The new 22nm Ivy Bridge processor was fastest when the memory modules were ran at their default memory clock rate of 1600MHz.. The processor was approximately 4% faster than previous generation of Sandy Bridge Core i7-2700K CPU, which was also run on the same motherboard with the same operating parameters. Interestingly, the overall score of Intel i7-3770K with clocked-down memory modules at 1333MHz was about 3% behind the pair of slower Sandy Bridge CPUs - Core i7-2600K and Core i5-2500. While some of the difference can be attributed to the stronger ASUS P67 motherboard's performance, the contrast in performance is rather surprising.
However, focusing on the workload breakdown, you can better appreciate how the performance scales better with the various CPUs. It seems that SYSmark's emphasis on productivity scores for its overall rating is way too high. The difference between DDR3-1600 and DDR3-1333MHz are not very obvious, but the Core i7-3770K did perform rather well as a whole - even rivaling or surpassing the massively powerful Sandy Bridge E processors like the Core i7-3820 and the Core i7-3960X. Clearly these behemoths were meant for workstation usage, not everyday usage scenarios of these benchmarks. Generally speaking, the new Ivy Bridge was about 20% to 30% speedier than the pair of Sandy Bridge CPUs, and a small margin ahead of the Sandy Bridge E CPUs.
With the results from Lightwave 3D 9.0 (64-bit), the Intel i7-3770K took pole position in all test situations. The different clock frequencies of the CPU's memory modules didn't affect its scores significantly. The raw CPU power of the Sandy Bridge-E processors failed to upstage the Ivy Bridge processor even in highly threaded workloads from this program.
