PCMark 7 includes a range of tests that give different views of your system's performance. In the Advanced Edition you can choose which tests to run. The common use and hardware component tests are unavailable in the Basic Edition.
Overall system performance is measured by the PCMark test. This is the only test that returns an official PCMark score. The Lightweight test measures the system capabilities of entry-level systems and mobility platforms unable to run the PCMark test, but it does not generate a PCMark score. Common use performance is measured by the scenario tests - Entertainment, Creativity and Production - each of which results in a scenario score. Hardware component performance is measured by the hardware tests - Computation and Storage - each of which results in a hardware score.
Starting off with PCMark 7 we can see some strong performance out of the Ivy Bridge processors. Due to the way Sandy Bridge-E processors have performed under PCMark 7 as well we see some great performance out of the IVB chips.
Comparing the 3770k at 4.8GHz and the 2600k at 5.2GHz, we can see that the 2600k does come out ahead, but it's not by much of a margin.

HyperPi is a front end for SuperPi that allows for multiple concurrent instances of SuperPi to be run on each core recognized by the system. It is very dependent on CPU to memory to HDD speed. The faster these components, the faster it is able to figure out the number Pi to the selected length.
For our testing we use the 32M run. This means that each of the four physical and four logical cores for the i7 and the four physical cores of the i5 is trying to calculate the number Pi out to 32 million decimal places. Each "run" is a comparative to ensure accuracy and any stability or performance issues in the loop mentioned above will cause errors in calculation.
Because of the lack of Hyper Threading on the i5 3570k it becomes hard to compare the CPU to the other ones here. We do see nice gains over its stock performance. More importantly we see the efficiency side of things come in to play here with the 3770k.
While 400MHz lower than the 2600k, the i7 3770k offers much better performance. Overall it's actually the fastest running CPU in this instance as you can see when comparing it against all our other CPUs.
