May be if you use 100+ of these (~14400 'computers') you can build a machine with emerging behavior, brain-like?
On a more serious note, what we need much more of is not the processing speed. What we need much more of is what I call "memory processability", which roughly means "how many times per second can you process the whole memory" - or something like that. Basically how much CPU is there per RAM. Indexing is a great hack, but a hack it still is. Memory and processing cells must be merged into a single, massively parallel chip.
Users recall them fondly. In the end, clusters became too cheap for custom hardware like this to compete.
I might be misinterpreting, but I think the phrase you're looking for is "memory bandwidth".
