I see lot of new machines and laptops now having 64 bit hardware and provided all drivers are correct, will WPF and corresponding .NET will run any faster on 64 bit machines? I dont see any documentation about .NET or WPF on 64 bit anywhere, but I would like to know the difference. I see that .NET has no specific API for 64bit architecture, it is a neutral platform, but what about WPF?

A:
If the framework is compiled to take advantage of extra instructions, there might be a slight performance increase but 64bit is more about address space than extra speed.
And WPF/Avalon is a subset of .NET v3 so, yes, it is neutral too.
Edit: Here's a good thread on 64bit JIT performance. (but note that the answers are a year and a half old - one would hope MS have improved things for 64bit users)

A:
WPF application run as 64bit processes on 64bit OS (unless compiled specifically to target only x86) just like any other .net application.
