:Mebibytes per second is a measurement of bandwidth, and a very limited one these days.  It's difficult to impossible to measure CPU performance in "bytes per second" because it does not simply transmit and receive data.  Some traditional benchmarks have been MIPS and FLOPS, though these too are very limited metrics when you consider the high amount of TLP, ILP, and vector capabilities in a modern "general purpose" processor.    03:06, 2005 Jun 6 (UTC)
