when i write application, sometimes i must check some things via cpuid. For example existance of fpu/mmx/sse/some instructions like cmpxch16b.

Is it possible, that cpuid will success on 1 cpu - one having SSE, and fail on other?

When my thread will be scheduled on other cpu not havins SSE, it would be bad.

Is it possible that in multiprocessor envorenment cpus can be diffrent?

I would say no. Especially if it's a multicore processor - that'd be a pain to schedule threads on. Plus I have no idea why a manufacturer would put different cores on a die...
