Where can I get a list of processing speeds in mbps for the major intel processors?
What are the MIPS ratings for major Intel processors?

In summary, CPU speed is a measure based on the clocking rate forced on a CPU, but does not accurately indicate final processing speed.

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.

linux kid,
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"?linux kid said:
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.

1. What is the meaning of "mbps" when talking about processor speeds?
Mbps stands for megabits per second and is a unit of measurement for data transfer speed. It indicates the amount of data that can be transferred in one second.
2. How is processor speed measured in mbps?
Processor speed in mbps is typically measured by the number of bits that can be processed in one second. This is known as the clock speed and is measured in hertz (Hz) or millions of hertz (MHz).
3. Is a higher processor speed in mbps always better?
Not necessarily. Other factors such as the number of cores and the efficiency of the processor also play a role in determining overall performance. A higher mbps speed may not always result in better performance if other components are not optimized.
4. Can different types of processors have the same mbps speed?
Yes, different types of processors can have the same mbps speed. However, their overall performance may still differ due to other factors such as architecture, cache size, and efficiency.
5. What is a good processor speed in mbps for everyday use?
For everyday use, a processor speed in the range of 1-2 GHz (1000-2000 MHz) is generally considered good enough for basic tasks such as web browsing, word processing, and streaming videos. However, for more demanding tasks such as gaming or video editing, a higher mbps speed may be necessary.
