The rpi is far more than a bit slower, more than the cores and clock counts imply. The pi is a slower microarch and is cache deprived too.
For somethings this doesn't matter but many of those things should probably be done on a proper microcontroller.
The odroid stuff appears to have a lot of users too, and these devices are less 'weird' than the rpi— they're more like the pandaboard and beagleboard— so there are less sharp edges to figure out.
That's why I'm hoping the next-gen Raspberry Pi will be 64-bit based on Cortex A53. They should skip the ARMv7 architecture and jump from ARMv6 to ARMV8. It should make things easier for the people maintaining the Raspbian OS,too, if they didn't have to support 3 architectures at once.
I have been assuming that it's most likely they won't make another board - or at least not another design.
I assume that, because in that case - they'd be fanfaring a lot more about how their newer design is being worked on. I'm seeing that they're more focusing on developing the userbase and utilities of the current board.
ie. with expansion cards, refining the software stack and such.
