Sreejith,
As has been stated in this thread, you should work hand-in-glove with your hardware vendor for these numbers as you are going to find that they will vary from system to system. Given the CPU that you mention, I think that you will be pleased with the SAPS they will provide and the resulting VM density that you will get.
Here are some published benchmarks that may give you some idea of what you can expect.
I hope that this helps.
