Tweak on a PDA

[Sachin Desai]

Anyone have experience of running Tweak on a PDA? What's the
performance like?
I'm leaning towards the Dell Axim 51V as it has Bluetooth and WiFi
which is a must and
at 624MHz I'd figure it should be able to run the applications at
decent speed.

Does this seem right? Any thoughts or insights would be appreciated.

My RISC OS machine is an Iyonix PC which runs a 600MHz XScale 80321 -
a very similar cpu to that in most PDAs - and tweak performance is
not particularly thrilling. Which, considering that under a large
suite of fairly complex benchmarks it scores about 30x Dorado, is a
bit depressing. Back in the old days (cue soft violin music, misty
filter on the lens etc) a score of >50% Dorado meant a quite snappy
machine. All those cycles are going somewhere so the question must
always be "are they going somewhere useful to me". Of course, a lot
of graphic performance these days can be gained with good GPUs and
good GPU programming. Do pocketPC machine have any of either?

Hi, Tim,
The Axim has a GPU, of I don't know wich power, so it could probably be a
better performer than your machine.

You might be in luck then; does it support openGL? That would
probably be a very good sign. The other downside is lack of a
hardware floating point unit but maybe, just maybe, the GPU can
handle enough of the detail graphics FP work to be useful. ARM have
never really got their act together wrt FP hardware; although it is
supposedly available on more recent designs it is quite rare to find
actual hardware with it. An ARM11 with fully specced caches and TCM
and multiple FP would be awfully nice.
