Photoshop Demo - on 68K, Pentium, and Native PowerPC
Demo:
1) On 68K Mac, launch Photoshop with demo file "MacPortrait". Now under the Filter menu, choose the Blur submenu, and then the Radial Blur selection - accepting defaults. This is a complicated graphics manipulation that really takes some number crunching Power. Start the 68K Mac on the blur. This is very complicated .. let it run for a moment, and let the audience gauge the speed.
2) Now go and switch one monitor on Pentium system. •••••• See Mazan's Script for Windows PC Applications, Photoshop section! ••••••
3.) Now let’s look at a prototype PowerPC native version of Photoshop (MAKE SURE YOU’RE IN 16 BIT COLOR !!!!_ - launch Photoshop app, typing the password “jade” when prompted. Use the magnifying glass to make the photo fill the screen if it doesn't automatically.
4.) Select the Filter menu, then the PowerPC submenu - then the Radial Blur selection - accepting defaults.
5) Start running, and watch it beat Pentium, even with a head start! This is a great example of the power of PowerPC and native solutions! PDM, our lowest cost system is beating a higher priced pentium with a Graphic accelerator! This is a very early Native version. Adobe is estimating that with some tuning, they will be running 50% faster than this beta code when their product ships!
(Practice your timing on this!)
Let’s look at another example program:
Mathreader from Wolfram Reasearch - on Pentium and PowerPC
GETTING READY TO DEMO
1. Mathreader is • Faster at 256 colors -use depth charge to change to 256 colors
DEMO:
1.) ••• Again, •••••• See Mazan's Script for Windows PC Applications, Photoshop section! ••••••
2.) Now load the same Mac Native PowerPC version of Mathreader. This version is a beta version that is a straight recompile from their current Mac version, with no special optimization. Load the same “four plot” graph. Click on the farthest right vertical line, to the right of the graphs to “select” them. Choose “animate graphics” from the "Graph" menu (Note that once animated, there are speed controls on the bottom left corner of the graph. Use the up arrow to crank it up to optimum speed if it isn't there already.
3.) Wolfram Research is reporting a 6 to 7 times performance gain with their recompiled apps on PowerPC over current high end Mac systems.
