Core i7-2600 vs i7-3930K
Description
Both models i7-2600 and i7-3930K are based on Sandy Bridge architecture.
"Sandy Bridge codename was originally ""Gesher"". The development began in 2005 and four years later, the first Sandy Bridge CPU was presented. The most prominent features are Intel Turbo Boost 2.0, AES encryption and SHA-1 hashing acceleration, Advanced Vector Extensions (AVX) 256-bit instruction set and the ability to have up to 8 physical cores or 16 logical cores through Hyper-Threading."
Using the multithread performance as a reference, the i7-2600 gets a score of 93.7 k points while the i7-3930K gets 155.9 k points.
Summarizing, the i7-3930K is 1.7 times faster than the i7-2600 . To get a proper comparison between both models, take a look to the data shown below.

Monothread performance graph
Monothread performance graphics gives the performance vs time. They are useful to measure the time it takes to the CPU to reach the maximum performance.
Usually, CPU's performance will be steady during these tests but if it has a slow frequency strategy, the first samples will show a lower score.

Multithread performance graph
Multithread graphs measure the performance against a heavy load during certain time.
If CPU's TDP doesn't limit the frequency and the machine is properly cooled, performance should remain steady vs time. Otherwise, the performance score will oscillate or decrease over time.
