Here thetas of anything surprising as integer at series 6 is shorter, than at 7. And on integer operations with the bad code optimization under a flow they, with other things being equal, will be faster. Yes, at systems on 6 productivity of a subsystem of storage is much worse, than at remaining modern platforms, without looking at frequency of the bus. Here, on it, even in the resulted test small lift-off 7 but if the task would get into a cache completely would be on the contrary is watched.
.... The Main lack of series 6 was not FPU, here, just, the considerable lag from the modern platforms on the optimized tasks (and today all such) is watched. But on majority FPU of operations series 6 fast, . does identical operations 6 for a smaller amount of clock periods, than 3 and 7.
..... It is a pity To me that these series 6 are laid off, I for technology equipment practically do not have changeover, well, unless , but it is necessary to alter and rewrite all.
