The VSX supports both scalar and vector instructions for both floating-point and integer, all happily mixed into a single register file.
We probably see here heavy microcoding and internal register-renaming.
The Power8 is internally surely not what it represents to the outside.

All in all comparing Gunnars 68080 to Power8 is a far fetch.
Power8 can not be a good example, if Apollo wants to go ASIC one day ... unless this ASIC should cost over $5000. Power is fast, but it runs hot and uses lots of silicon.
