As compared to? I routinely run SPLAT! coverage plots on my trusty
1.333 GHz Pentium III based T23 laptop. Yes, it may take a couple of
minutes to chew through some of the more demanding plots. For SPLAT!
purposes, enough computing power is available on the used market for
even the most frugal ham.
Even in the case of SPLAT!, memory is more important than CPU speed. I
have 768 MiB in the laptop and a full GiB wouldn't hurt, but it really
isn't worth tossing a 256 MiB chip for a 512 MiB one. Opening the
PPM files generated by GNU Plot in the Gimp is no problem for my T23
either. I do this work on a Slackware partition which is quite a bit
leaner than my Debian partition which I have set up for as a rich
desktop.
