Where can I get a list of processing speeds in mbps for the major intel processors?
millibits per second?
what bits? going from where to where? undergoing what transformations? it seems more like memory or bus speed. they use flops for CPUs.
Well these processors have pipelines of say 15-30 stages or whatever. That means that an instruction has a 30 cycle turnaround time. Of course, the instructions are 'pipelined' so that many are put into the pipe one after the other. There is branch prediction logic to know what future instructions to put into the pipe.
Of course mistakes will be made and then there is a lag to bypass those erroneous instructions that were pipelined. So the performance can differ depending on the software itself. I think that usually the clock speed and the pipeline length are good indicators of the processor speed.
Notably, the earlier Athlons had a much shorter pipeline than the P4's which led to them having a PR rating, like 1700+ which actually ran at 1200Mhz or whatever, don't quote that figure.
mbps is not a meaningful cpu performance indicator because (Intel) CPUs process in parallel. CPU speed is a measure based on the clocking rate forced on a CPU but does not accurately indicate final processing speed because different CPUs have different bus schemes and op code capability. "Bus speed", in XHz and slower than CPU speed, indicates how fast a system bus transfers wide words in parallel. Google "Intel specs".
Perhaps you mean MIPS which stands for "million instructions per second"?
In that case there is a Wikipedia http://en.wikipedia.org/wiki/Million_instructions_per_second" that lists the number of MIPS for various CPUs.
According to the article an Intel Core 2 Extreme QX6700 is rated at 57063 MIPS. Quite amazing, an IBM System/370 model 158-3 from 1972, which at the time was considered a pretty powerful computer, is rated at only 1 MIPS.
