Question

I know that since ~2004, Moore's law stopped working for CPU clock speed. I'm looking for a graph showing this, but am unable to find it: most charts out there show the transistor count or the capacity per year.

Where can I find some data showing the CPU frequency of computers (anything is fine, personal computers, servers, laptops, ...) from the last few decades to today?
Raw data that I can plot myself would be fine as well (hum, probably even better).

Was it helpful?

Solution

Bob Warfield wrote a blog post (A Picture of the MultiCore Crisis) that has the kind of graph you're looking for.

Update

It sounds like the Stanford CPU DB has what you're looking for. You can browse visualizations and download the raw data.

OTHER TIPS

The graphs you want are printed in the book “CMOS VLSI Design” Weste/Harris (2005), on page 5 of the freely available introduction.

See Sutter, The Free Lunch is Over (2005): it has graphs, discusses how various processor characteristics relate to performance of actual programs, and makes some predictions that turned out true, as far as I can tell.

The 5th edition of Computer Architecture, A Quantitative Approach has several related graphs.

The clock rate graphs is divided in 3 parts, from a 5MHz Vax in 78 to a Sun SPARC at 16 MHz in 86 (15% per year), to an Intel Pentium 4 Xeon in 2003 at 3200 MHz(40% per year) to an Intel Nehalem Xeon in 2010 at 3330 MHz (1% per year).

The performance graph is also divided in 3 parts, from the VAX 11/780 in 78 at relative performance 1 to the VAX 8700 in 86 at relative perf of 5 (25% per year), to an Intel Xeon in 2003 at relative perf of 6000 (52% per year) to an Intel Xeon in 2010 at relative perf of 2400 (22% per year). Note that SPEC on which the performance measure is based has automatic parallelization turned on and so multiple core of a processor are used here.
