Monitor Setup

Before watching charts, using desktop mode and playing games, setting up your monitor's contrast & brightness levels is a very important thing to do. How do we know this? Because we receive a couple of emails every now and then telling us that a reader can't distinguish between the benchmark charts (colors) in our reviews. We realized, if that happens, your monitor is not properly set up.

This simple test pattern is evenly spaced from 0 to 255 brightness levels, with no profile embedded. If your monitor is correctly set up, you should be able to distinguish each step, and each step should be roughly visually distinct from its neighbors by the same amount. As well, the dark-end step differences should be about the same as the light-end step differences. Finally, the first step should be completely black.
 

DhryStone CPU test

We make use of a multi-threaded Dhrystone test from SiSoftware Sandra, which is basically a suite of arithmetic and string manipulating programs. Since the whole program should be really small, it fits into the processor cache. It can be used to measure two aspects, both the processor's speed as well as the optimizing capabilities of the compiler. The resulting number is the number of executions of the program suite per second.

Alrighty, first stop is the SANDRA DhryStone and Whetstone tests. These two tests are pure unadulterated 100% CPU tests that run completely within the CPU + cache memory itself. A perfect test to observe the general efficiency per core.

Though one of the oldest, Dhrystone remains a simple yet accurate and effective way to show you RAW CPU processing performance making it a very good indicator. 

The highlighted bars are the processors tested, the other processor/mobo entries are there for comparing CPU/APU and respective platform scaling throughout the benchmark session.

Whetstone FPU

The Whetstone benchmark is a synthetic benchmark for evaluating the performance of computers. It was initially written in Algol 60, back in 1972. The Whetstone benchmark originally measured computing power in units of kilo-Whetstone Instructions Per Second (kWIPS). This was later changed to Millions of Whetstone Instructions Per Second (MWIPS).

The Whetstone benchmark primarily measures the floating-point (FPU) arithmetic performance. A similar benchmark for integer and string operations is thus Dhrystone.
