[filmscanners] Re: PC memory type for filmscanning (OT - slightly)

["Herm" <hermperez@worldnet.att.net>]

I have noticed this too, I briefly played with a customers Pentium IV 1600 and
compared it to my Athlon 1000, mine with 512mb of PC133 vs. 512 of Rambus for
the Pentium.. I manipulated large images (50-100mb tiffs), levels, unsharp mask
etc.. I was shocked to find that the Athlon would consistantly perform faster
even when it had a much slower processor. After further testing I found out that
the Pentium had substantally faster memory throughput, but the athlon was about
40% faster in math operations (integer and floating point operations).. so
overall photoshop performance is not fully dependant on memory performance..

and the funny part is that the Pentium IV system is a lot more expensive!.. If
anybody is interested I can forward (to them) the test result logs for both
systems.
