what does superpi measure? the 'effect' of an overclock.
http://en.wikipedia.org/wiki/Super_PISuper PI is single threaded, so its relevance as a measure of performance in the current era of multi-core processors is diminishing quickly. As the calculation times become faster and faster, Super PI is also becoming a rather poor stability test due to the need for a stability test to run long enough to stress the hardware.[citation needed] Many users are moving to Orthos or OCCT for their stability testing since those are multithreaded programs.
superpi is for single core cpu's
would not a multithreaded pi test be a step forward? for everyone?
the more programs that are altered to run in parallel the more benefits to the consumer (ie me)
i dont even know whether you can multithread a pi calculation..![]()

you are mistaken if you think people are here to seek for 24/7 stability
XS in my mind is about pushing the limits in tech whether 3d or Pi
you guys keep confusing stability with benching. they do not go together. have you ever seen someone prime on subzero cooling....if you have they were just joking around put it that way.....it is just not what it's about
Pi can be run in multiple instances if you want to load all cores but who cares about loading all cores.............it's about Pi benchmark and you can even draw conclusions on rough 3D stability on basis of Pi clocks even........in AMD days dual 8m on dual core was good for any 3d bench, Intel i have not done a lot of 3d but seems about 100Mhz clock speed reduction on 32m stable
why is pi important? Pi is the best piece of software to determine how much RAM frequency and timings impact on performance of a system but it's true it does not necessarily translate across all benches and some 3d apps like tighter timings and other benches like higher frequency at looser timings ......
i start with every new CPU and RAM with Pi and quick 10m jerks in orthos to gain an idea very quickly where the system is at
24/7 stable systems people are soooo delusional about what are (for majority of people) nothing more than internet boxes and then the rest (bit of gaming, bit of video, folding or whatever you get up to) ..... you really don't have to go pushing the limits with 24/7 clocks as it just won't give you a massive advantage to squeeze out another say 200 MHz quad which is already stable at say 3.5GHz for daily use....all you will do is create problems in terms of heat, noise

if you say so; you're the one with a closet full of hardware - not me
i am more interested in cpu design/architecture etc whether it is amd or intel;
i like seeing evolutions and changes.
bottlenecks and frequency limitssuperpi is good for that?
superpi is one calculation; arent there many other types of calc/instruction?why is pi important? Pi is the best piece of software to determine how much RAM frequency and timings impact on performance of a system but it's true it does not necessarily translate across all benches and some 3d apps like tighter timings and other benches like higher frequency at looser timings ......
if it helps you maximise optimum timings etc and frequencies yadada, wellif it helps it helps
you may as well use a sooped up single core imo. for superpi. - with your super cooling etc.
i'll ask again: what does superpi measure? raw compute power? no of transistors? effectiveness of cache? etc etc
does it measure overall cpu design or just one part of the cpu's ability?
i suppose you could design/taylor a cpu specifically to run superpi

you got more than me :P![]()
some might say it's OCD (obssessive compulsive disorder)
yes i do suffer a bit from that![]()

All benchmarks which AMD losses become irrelevant...move along please.
Im waiting for some actual numbers myself then perhaps I will draw a conclusion.
Super Pi measures joined computational power of CPU / Ram / Nb.what does superpi measure? raw compute power? no of transistors? effectiveness of cache? etc etc
does it measure overall cpu design or just one part of the cpu's ability?
It is highly dependent on CPU/Ram clocks, ram timings and northbridge arhitecture. It is a tool that measures the performance of CPU's clock per clock, using only one core. And if you want to se the overall calculus power, you can use wprime![]()
