Already read that thread. Those Adobe guys Chris Cox, Scott Byer and Marc Pawliger seem very sheepish on the issue.

Note they all are very quick to put down Core Image and the only explanation why not Core is by Scott how is wrong AGP 8x throughtput is 2.1GB/s and with PCI Express in the new G5s it is 4GB/s but its really the power of 16 pixel pipelines lines in the x800 GPU which are basiclly vector units even the new Dual CPU with Dual Core ( Now for the math a G5 core has 2 vector units so 2x2x2=? ) only has 8 and remember that with only one gpu ( using the new x850 and sli you'll get 4 GPU's each with 16 pixel pipelines) and photoshop currently doesn't make very good use of even 4 vector units in like a 2.7Ghz Dual G5 with 8GB of RAM it putts along at 60%-70% usage on even large files when doing tasks that are "Optimized" for the G5. I too have dealt with this.

And on the GPU issue go have a look at Evans & Sutherland they make Image proccessing equiment use ATI GPU's upto 64 GPUs in one box. They are used for every thing form flight simulators to Render Servers.

Also when Core Image is Hardware accelerated with the GPU its not like it only uses the GPU it does still use the CPU and its vector units.

Of course Adobe's programmers are going to poo-poo CoreImage! They didn't write it and already had all of it's features in PhotoShop. What makes CoreImage a value is that it makes it easier to write or port graphic intensive programs to the Mac platform and incorporate features that were previously Adobe only domain.

CoreAudio's been around awhile, and most professional sound software now uses it since it makes it a lot easier to implement those features. There are some sound programs that existed before CoreAudio, that don't use it though.

I think I recall reading some years ago that the Photoshop source code was something like 5 million lines of code. Such a program takes much more than "months" to develop.

Even if we were to make the assumption that using new technologies might reduce the number of lines of code to a mere half-million (500 KLOC), then (from the tables in Steve McConnell's "Rapid Development" book), the fastest possible time to write such an application would be about 20 months (with a team of 70 developers).

Note: the open-source graphics program "GIMP" had something like 400 KLOC in its 1.2 version. Presumably the latest versions are a lot more. And the GIMP of course uses the GTK which is now over 600 KLOC.

OK...... Finally........... Adobe have seen....!!!!!!!!!

I've been speaking with Adobe direct on this matter since i first posted the original thread. And after me running around 50 or so tests and giving them results back, they have now posted articles on their tech website.

Photoshop has a problem with images when the G5 has more than 4GB RAM installed.
