Normally, the size of a pointer or general-purpose integer register is used
to determine 32 or 64-bit rather than the size of the FP unit since nearly
every processor more powerful than a microcontroller supports 64-bit FP.
even the 8086 (16-bit) supports 64-bit floating point (or even 80-bit) with
the 8087 math coprocessor. Also, recent intel processors support 512-bit FP
registers (the avx512 instruction set), but it's only a 64-bit processor.

From some searching I found a linux port for the WiiU, however, it only
supports booting 1 core.

The main benefit of Power Macs is the software's highly likely to work,
whereas both the WiiU and PS3 are less likely to.

yup. :)
