We were closely monitoring CPU Boss - a site dedicated to comparing two processors side by side. The way it did was create a database of the processors and, when, someone searched for two processors, it looked at the data of the two processors and listed them side by side.
Well, this thing works in some scenario where the two processors are of the same line. For example when both the processors belong to the Haswell line of processors. In such case, if you compare the clock frequency of the two processors, it makes sense to compare the frequencies.
However,if you look at these shoddy websites, things fall apart. They often compare the clock frequencies, number of clocks and other parameters of two processors of heterogeneous families - like one is from Intel and another is from AMD.
Listing just the data is not going to work. The processors today are more complex in the sense that they also encompass the Graphics Units built into it. And it is really hard to compare the GPUs ( Graphics processing Units), just based upon the underlying data.
What we need is some explanation on the individual comparison of the processors. This is where we come into picture. We compare two processors, not only based upon the underlying data but also upon the underlying architecture. The data is still used, but not as the only source of information. It is complemented by individual explanation of the data and we derive the results and explanation.
Sometimes ago, findthebest.com also tried the same thing and failed miserably. There are few sites that do the job a bit better - notebookcheck.com and anandtech.com do a better job and creating a database of the CPUs. Both of them back up with a lot of time they spend in actually reviewing the CPUs.
