Wait. You're right. I did a double-take then doubted myself.

I can't find anything historical that used 3.2kHz memory access speeds, but I'm pretty sure there was something out there... from the 1960s.

That speed is slower than magnetic memory; it could be delay-line memory, which would be even earlier.

I'm not sure what your question is. It's shared with the integrated GPU, so faster is better even if it means that it costs a bit battery life.

Memory speed is usually in MHz, not Hz. They're just making fun of the mistake.
