CPU DB, a database of processors for researchers and hobbyists

A link to the ISSCC keynote by Mark Horowitz, curator of cpudb. IMO worth a listening to for most anyone interested in CPU performance related issues. http://isscc.org/media/2014/plenary/Mark_Horowitz/NewStandar...

The plots shown in his presentation basically show off the underlying data in cpudb.

Nope:

  Failed to connect to cpudb.stanford.edu port 80: Connection refused

The actual link to get the .tar.gz archive is http://cpudb.stanford.edu/cpudb.1416196069.tar.gz (on the download page, both links points to the .zip file). They are basically the same size anyway (~728kiB).

A few interesting charts showing the evolution of CPUs:

* Transistor size (http://cpudb.stanford.edu/visualize/technology_scaling): the process is still regularly scaling down

* Clock frequency (http://cpudb.stanford.edu/visualize/clock_frequency): processors do not tick significantly faster than 4GHz, a speed they reached in 2004/2005

* Performance (http://cpudb.stanford.edu/visualize/performance_by_freq_and_...): I am still unable to display this graph

The clock frequency graph shows a processor at 21.3GHz. It's the Z3480, whose clock actually ticks at 2.13GHz (http://ark.intel.com/products/70102/Intel-Atom-Processor-Z34...).

I love that it goes back to MOS 6502, Zilog Z80 etc. It also includes the WDC 65C02 which is still in production.

Interesting. Pity it does not feature anything DEC beyond Alpha.

Is it down? Any mirrors?
