Bandwidth isn't really most of the issue. It's latency. It's the amount of time from the CPU requesting a segment of memory to receiving it, which bandwidth doesn't effect.

Depends on your workload and access pattern.

...I'm saying can be faster. Not is faster.

Yeah, but the point of RAM is fast random (the R in RAM) access times. There are ways to make slower memory work better for this by predicting what will be needed (grab a chunk of memory because accesses will probably need things with closer locality than pure random), but it can't be fixed. Cloud memory is good for non-random storage or storage that isn't time critical.
