64-Bit JM 9.7 Reference Encoder

[CyberGuy]

I wanted to show an example of the speed difference between 32-bit and 64-bit compiled code. I am using the H.264/AVC JM 9.7 Reference Encoder, http://iphome.hhi.de/suehring/tml/, and have compiled the same code into a 32-bit version, lencod32.exe, using Visual Studio .NET 2003, and a 64-bit version, lencod64.exe, using the 64-bit version of the Visual C++ 7.1 libraries and build tools. The 64-bit version finishes approximately 13% faster than the 32-bit version; keeping with the universal 5% to 15% expected speed increase. You will see this universal speed increase over any 32-bit application, from a simple timed loop of “Hello World”, to very broad system resource intensive applications.
