Even though the maximum processor capacity on smartphones is 1Ghz, many of them can be overclocked, often with a 10% increase or more. Overclocking basically means that you increase the capacity of a chip, such as the CPU. For example, the 1Ghz Snapdragon processor on the Nexus One has been overclocked to 1.3Ghz.
You will probably understand that a higher clock speed should result in better performance. How much it increases, depends on various things. Most important factors are the processor model and architecture, the corresponding hardware, but also the software. Every different ROM will respond differently to the clock speed. So, even if you have the same clock speed, there could still be a significant difference in the actual performance of your phone when using different ROMs. And that’s exactly what XDA member nief1313 has been busy with lately.
The are already lots of ROMs available for the HTC EVO. Nief1313 decided to compare them not only ROM vs. ROM, but also ROM vs. Overclocked ROM. Almost everything has been measured: he used three different benchmarking applications, tested the battery life, and added other features of the ROMs. Starting today, a total of 10 ROMs will be tested and benchmarked:
The results will be placed in a table. The project isn’t finished yet, as there is much data still missing. Yet, there is already some pretty interesting information available.

Update 8/6: Updated the spread sheet and put it up and google docs Niefs Rom Comparison
There are now explanations of the tests and I am going to start testing today. Also, looking for testers.
I have posted my scores for part of Fresh.
The Google Docs spread sheet is constantly updated, and we expect a lot of data will be added soon. To follow the discussion about the spreadsheet, continue on to the thread.
Concluding, this is a nice initiative, and it will really give us some more insight in how well every overclocked ROM works. Because after all, that’s what XDA is for: sharing knowledge._________
