I am considering an Dell Precison 64-bit workstation with an Intel Xeon Processor. I would like to know whether the Floating-Point Unit (FPU) is 64-bits. I have Googled on the web and searched on the Intel web site and cannot find the answer.

Thanks,

WWBD - :)

I suggest that you contact Dell about this. I bet they are much better about answering questions BEFORE you buy than AFTER. :rolleyes:

*laughs* I'd love to see the Dell support guy in their Indian call centre answer that question.

It depends on your code. You can use 32bit (float), 64bit (double) and 80bit (long double) floating point values even on a 32bit CPU. Both AMD's and Intel's 64bit CPUs have extra 64bit instructions in addition to the standard 32bit i386 instruction set, if your compiler supports them. There are also the MMX, 3DNow, SSE, SSE2 and SSE3 SIMD instructions you can use to gain better floating point precision and speed. This question really belongs in the development forum.
