SiSoft Sandra is a diagnostic utility and synthetic benchmarking program. Sandra allows you to view your hardware at a higher level to be more helpful. For this benchmark, I will be running a broad spectrum of tests to gauge the performance of key functions of the CPUs.
Cache and Memory
Power Management Efficiency
AIDA64 Extreme Edition: is a software utility designed for hardware diagnosis and benchmarking. I will be using the CPU Queen test that looks for the solution to the "Queens" problem on a 10x10 chessboard. This tests the branch prediction capabilities of the processor. The FPU Mandel test measures double precision floating point performance through computation of several frames of the "Mandelbrot" fractal.
Higher is Better
In all of stock frequency tests, the Core i7 3820 delivers a higher level of performance than the 2600K and significant improvements over the aged Core i7 920. When overclocked, these margins stay relative to each other, based on the core clock similarities between the i7 3820 and 2600K. In applications that can use it, the quad-channel memory bandwidth on the Core i7 3820 provides a significant point of difference to the dual-channel Core i7 2600K.
