From: pravi on 9 Mar 2010 03:37 Hello all, I need to buy a new laptop mainly for doing compute intensive 3D image processing using Matlab. Does anyone have any suggestions for a good configuration or product suggestions? Thanks in advance. Ravi.

Skip matlab. That step alone will boost performance by a factor 10-50-100. No kiddin'. Apart from that, the obvious comment is that if you intend to do graphics, then you will need to address the graphics performance of the candidate computers. Rune

Eventually, the application will be ported to a stand-alone processor. However, the initial proof-of-concept has to demonstrated with matlab. So, currently, the interest is not in performance as meant by time, etc. but more to see if our algorithmic design functions. Any suggestions for laptops with very good graphics performance? Thanks again. Ravi.

Again, skip matlab. Matlab's matrix-centric semantics is a straight-jacket you would like to stay away from whenever possible. Such a simple operation as computing the histogram of an image is a major understaking in matlab, both what coding time [*] and run-time is concerned, but can be coded in mere minutes in C++, using the STL containers. And the C++ version runs a *lot* faster, 10-50-100 times faster, than the matlab version. [*] I know; matlab have built-in functions to compute the histogram. For the sake of this argument, though, take a minute to contemplate how you would do it to implement your own version. > Any suggestions for laptops with very good graphics performance? No. Ask your local dealer. Rune

If you want to use the CUDA/Jacket plug-in you should go for a laptop with a high end graphics card based upon the GeForce 300 or similar (or maybe some vendor will include the Fermi scheduled for availability later this month in their laptops).
