It's a move.
That's 25 million 32 bit integers per second. I think a 68000 CPU from 25 years ago could nearly equal that. Well, I can't say. Maybe they wired it up to an 8 bit DRAM chip, an 8-bit channel.
Even if that was 32-bit, the memory bus was at best 40MHz then (say an 68040 in a Quadra 840AV, which is big iron compared to an original 68000). So even if you could fetch a word every cycle, that would be 160MB/s read, 80MB/s R/W. And I doubt it could every cycle :-)
An 8 bit data channel is what you connect a Z80 to. Actually if you could put one 32 bit register into a Z80 and brought out 32 address pins, I think that would be more interesting for me. If you had been able to put a Z80 with 4 Gbytes of RAM in 1979 I'm sure there the world would be a very different place, with a very different style of programming and computer science would have taken very different research directions.

RASP PI ZERO 3 3 01.04.2016
Just a reminder that the $15 price tag on the PINE64 has no WiFi board included. That's an extra-cost feature, probably more than the board itself!
Pretty amazing how cheap and capable these little computers are becoming. Like most of the computers in this class, the PINE64 does have a large number of GPIO pins (3.3v). Also this board has a built-in LiPo charging circuit, something that is sorely missing on the Raspberry Pi.
It's also interesting to see that these little boards are actually useful and used for creative things. With the older generation of devices, they all ended up in my desk drawer, I'm afraid. Devices like the SheevaPlug, GuruPlug, Raspberry Pi 1, etc, that turned out to be much less useful in practice than in theory. I suspect 90% of the original Pis never made it out of drawers. But I've seen a few cool things done with it.

Next I have to get those wlan modules....and then the wiring :)
the PINE64 is kickstarter project, there's no telling how long it would take for you to receive a unit, I made that mistake once with Parallella and will never do it again, it took over a year last time.
