In the interesting of maintaining rigor, I'd like to know if there is
any hard data to back up this claim.. i.e. profiling which demonstrates
the memory bandwidth versus CPU restrictions, etc on one or more

(To be fair I suppose this means that we need a standard regression
test/benchmark for a real-time audio system, PDSpec?)

The reason I ask is that I'm interested in massively multichannel

Also I am curious as to why Intel would have less memory bandwitdth...
intution suggests it would depend on the type of system memory used...
rambus versus SDRAM, etc?
