Hypothetically, would 2 CUDA cores at 1 MHz function the same as 1 CUDA core at 2MHz?

Not really. The idea behind CUDA and GPGPU is that you can do lots of simultaneous processes. So while the one core is faster it can't do two things at once. However, the two separate cores will have to recombine the finished product if we are talking about running the same job.
it depends if there supposed to be parallel tasks the 2 single cores would finish slightly quicker.
reason being is the single core would have to stack the task, run the first 1 check that its finished and the load the second it may only be 1 or 2 cycles difference but there will be a slight 1.
you get the same penalty when you have a hyper-threading cpu with 2/4/6/8 cores and 4/8/12/18 threads.
