In reality, it is about 1/4 of this or so, or 200M bytes per second. But note at that speed, you are doing *nothing* else, just pumping data thru the cpu... and since copies are a read/write pair, even getting 200M bytes per second is difficult... And a second issue is that this will blow hell out of cache while you are doing it, naturally... :)
