Found some NBench figures of both to compare.

Sam440: http://amigadev.free.fr/powerpc/nbench.html

Result scores (for 800 MHz each):

Efika MX:
- MEMORY: 4.87
- INTEGER: 5.15
- FLOATING-POINT: 1.22

Sam440 (scaled from 553 MHz | scaled from 667 MHz):
- MEMORY: 2.54 | 2.52
- INTEGER: 5.13 | 4.46
- FLOATING-POINT: 3.56 | 3.56
