x264 HD Benchmark 5.0
by graysky
updated by Adrian Wong & Dashken


Initial Setup

Download and install AviSynth 2.5.8 (needed to run the benchmark). You can get it from this link or by simply double-clicking on the link provided in the benchmark package.

Then extract the files in the RAR package to a folder of your choice. If you do not already have WinRAR, you can download a copy here.

That's it!

Important - If you are using an Intel Core i7 or Core i5 processor (or their Xeon brethren), please be sure to turn off Intel Turbo Mode in the BIOS for accurate results! Similarly, if you are using an AMD processor that supports Turbo Core, please disable that as well. Otherwise, please inform us that your results are based on a CPU using Turbo Mode or Turbo Cache.


Running The Benchmark

Simply double-click on the Run Benchmark.vbs file. It will launch a window that appears like this :

Before the benchmark begins, you will be asked to enter a file name for the results. It really doesn't matter what you use; but be descriptive - it helps you remember which set of results corresponds to which overclock or computer. You can use the CPU multiplier and FSB speed as the file name (333x9, for example), or any other description for the matter.

After you hit <ENTER>, the benchmark will start. It will run through a 2-pass encode of a short 1920 x 1080 video clip a total of four times and then write a file containing the results along with relevant system specs.

Please do not use your machine while the test runs to allow for an accurate result.

You can test your machine at different overclocked levels, but it is a good idea to also test it at its stock level so you have a baseline to compare the overclocked results with.

Here is an example of the data output when the benchmark finishes :
