HP 48G -------------------------- 53m40s ------------ 717.928325369
HP 39GS ------------------------ 20m28s ------------ 717.928325369 (EDIT)

My HP48G is currently running (39 minutes and counting), with only FLAGs 02 and 03 set

The HP 50G produces the same result, as it should, and takes about as long, 10s of minutes anyway, despite having a 50MHz ARM processor because it runs an emulator.  I am not up to timing it accurately.

It is kind of sad actually considering that a processor designed and built 20+ years later draws more power to do less.

stand allone, yes, pocket, no.
.. and full of Nixies  :)

The 50G was just emulating a Saturn processor to be able to leverage everything that had been written for the 48 series, so yeah it was not that much faster than the 48 in the end. It was faster for some tasks, and a bit slower for others. It was just a transition product IMO.

The later 39gII and Prime were using 100% rewritten and native code. Eons faster. The nostalgic wish HP had ported more of what was available in the 48/50 to the Prime. But those address the student market rather than professionals. I guess this is related to the point raised in this thread, that professionals increasingly use computer tools rather than true calculators, so the market has shrunk and doesn't interest the major players that much anymore. It's not just with HP; all other major manufacturers (TI, Casio, ...) mainly release calculators for students (not to say they are not usable for professionals, but they are clearly not tailored for them as the old HP ones were.)
