As a person currently working with both CUDA and the AMD Stream SDK, I am pretty excited about Larrabee. If nothing else, I hope Intel will simply provide better documentation and perhaps better software tools :|
Intel got absolutely spanked by the Athlon64 for ~5 years and they're not about to repeat that again.
Ah, here it is: http://www.anandtech.com/cpuchipsets/intel/showdoc.aspx?i=34...
Of course, if it ends up being a G45 class chip, it's not going to be much to write home about (performance wise). Hopefully it ends up being a Larrabee variant, but that might be hoping for too much.
I'm interested to see what AMD and Intel end up doing with an on core GPU. It could be really interesting from a GPGPU perspective as you could eliminate the current need to ship things from main memory to GPU memory.
This is the dirty secret of Fusion. Moving a dog-slow GPU from the chipset to the processor still leaves you with a slow GPU.

Unfortunately, a GPU tends to have ~150 GB/s of memory bandwidth while a processor socket has ~30 GB/s. Is it worth a 5x drop in bandwidth to avoid the PCI Express bottleneck? Maybe...
