The notes for XNA 4.0 Refresh state:
"SIMD (Single Instruction Multiple Data) support has been introduced for XNA vector and matrix types, providing
significant performance advantages."
Which platform(s) does this apply to?
I've seen it mentioned elsewhere specifically relating to NEON support in phones, but does it apply to PC and 360 as well?
The notes also mention generational garbage collection. Is this for phone or 360 or both?
