Core i7-4820K vs i7-4930K
Description
Both models i7-4820K and i7-4930K are based on Ivy Bridge architecture.
"Ivy Bridge is the last Intel microarchitecture for which there is official driver support for Windows XP . It is made under 22 nm Tri-Gate transistor (""3D"") technology and is basically a Sandy Bridge shrink. It has PCI Express 3.0 support and RdRand instruction for security tasks."
Using the multithread performance as a reference, the i7-4820K gets a score of 134.1 k points while the i7-4930K gets 198.3 k points.
Summarizing, the i7-4930K is 1.5 times faster than the i7-4820K . 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.
