Is it possible to write software that will run on Intels processors with Intel EM64T, and AMDs 64-bit capable processors?
Yes, in most cases. Even though the hardware microarchitecture for each company’s processor is different, the operating system and software ported to one processor will likely run on the other processor due to the close similarity of the instruction-set architectures. However, Intel processors support additional features, like the SSE3 instructions and Hyper-Threading Technology, which are not supported on non-Intel platforms. As such, we believe developers will achieve maximum performance and stability by designing specifically for Intel® architectures and by taking advantage of Intel’s breadth of software tools and enabling services.
