HP-Unix Hardware benchmarking

Hi everyone,

I'm working on one HP-Unix application which we have to port completely onto Windows xp. Before that I have to compare performance of two different machines. My HP-Unix is running on HP-C8000 workstation and windows XP machine is intel Xeon. Now the problem is to evaluate the performance/benchmark of these two machines interms of OpenGL & CPU performance parameters.

Does anyone here can share there hardware benchmarking experience with me?

I Gone through SPEC.org. , I think it may create problems during compilation.

Is there any other alternatives available for benchmarking?

Please reply .....
Thanks in advance ...
