I'm looking at getting a new laptop and was wondering about what 
processors are deemed to be the best. I basically have a choice between 
the Intel® Core™ processor Solo U2100 (1.6 GHz) and the Intel® Core™ 2 
Duo U7600 (1.2 GHz). Both machines comes with a gb+ of RAM. With regards 
to the Core 2 am I right in assuming that most applications don't 
utilise dual processing thus leaving one chip idle while that other does 
most of the work? If that's the case won't I get better performance on a 
higher speed single chip? My current machine is a 1.8Ghz pentium M and 
it performs fine but my employers are giving me the opportunity to 
upgrade. Any ideas?

Rory.

This probably means nothing for WinXP with Intel Dual Core, but my Dual G4
PPC Mac running OS X 10.2 does an excellent job of balancing tasks between
processors.  When I run Csound with top running in another terminal, I can
clearly see Csound using nearly 100% of one processor while the other
processor runs the GUI ("TrueBlueEnv" I think it is called).  (I don't think
Csound always stays on the SAME processor -- the tasks sometimes flip-flop,
I believe).

Thanks for the replies. By the looks of things the core 2 duo is the way 
to go. Either of then will out perform my current laptop and I've never 
really had any performance issues with it so I don't anticipate any 
problems with a quicker CPU!

With the core 2 duo then I can install ubuntu studio 64 which would 
provide extra umph for most applications? When building software on 
64bit systems are there any special considerations that need to be taken 
into account?

Hi Rory, hi list,

I highly recommend 64 Studio as Debian based 64bit Linux distribution
http://64studio.com/
and they somehow even solved the problem with the Flashplugin in the 
latest version so there is no problem with the occasional Youtube break...

Cheers,

Malte

presentation of Minicomputer softwaresynthesizer

This certainly seems to be the forerunner at the moment. Thanks for the 
feedback.

Rory.
