quote: As a recap, there are 3 parts of a modern CPU: General registers, address pointers, and data bus. In actuality, there is a few more, including external address bus. A 128-bit CPU typically refers to the first one of those, using 128-bit general registers. It would not be inconceivable, and actually highly likely that the external address bus of any 128-bit ARM would still remain 64-bit (or even less... perhaps even 36 or 40-bit), and yet it could have a significant on its speed for many different types of operations, including networking, video processing, and cryptography.
quote: Vector processing is pretty much only used for FP math
quote: SSE was actually all originally integer functions.
quote: That was not the case when CPU FP was on an outside chip.. but these days... If you look inside any modern processor the 128-bit registers exist in the FPU.
quote: The FMAC performs the SIMD instructions in fact, using FMA3. Two guesses what those Fs stand for.
quote: and outside of SIMD what purpose is there for 128-bit silicon?
quote: Fused, meaning single precision, as in floating point.
quote: To bring this full circle, 128-bit SIMD registers does not a 128-bit chip make, or all current chips would be considered 128-bit...
