Well I don’t, I get much, significantly much, less. ARAnyM, or full-system emulation in general, has very specific workloads that can only be helped with two things: • crank up the MHz (of the CPU, RAM, system bus, I/O, etc.) • use less cycles per instruction, including conditional jumps Most CPU manufactures do these things instead: • parallelise (including hyperthreading) • use less cycles per instruction, penalising conditional jumps • use deeper pipelines • do some sort of power management All of these *hurt* the performance of full-system emulation. Not scientifically proven, just a rule of thumb from my own understanding of the problem. May contain nuts. May be wrong in parts. But should be right in general. bye, //mirabilos -- 17:08⎜«Vutral» früher gabs keine packenden smartphones und so 17:08⎜«Vutral» heute gibts frauen die sind facebooksüchtig 17:10⎜«Vutral» aber auch traurig; früher warst du als nerd voll am arsch 17:10⎜«Vutral» heute bist du als nerd der einzige der wirklich damit klarkommt -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe".
