Does anyone out there know how the X performance of a DEC 5000/200CX compares with a 5000/200PX? I know that the PX graphics subsystem utilizes the PixelStamp chipset to perform scan conversion, but does the X server take advantage of this hardware? Is there any hardware in the PX that is designed specifically with X performance in mind, or does the PX address other graphics API's, e.g. PHIGS? On a related note, how does the X performance of the 3D systems (the PXG and PXG-turbo) compare to the 2D systems? Did DEC make sacrifices in X performance in order to speed up the 3D cases? It appears that IBM made exactly that kind of tradeoff in their offerings for the RS6000 line..... Thanks for any info! --Rajeev /\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/\/ ARPA: rajeev@caf.mit.edu UUCP: ....!mit-eddie!caf!rajeev "Do they think we can be frightened by men with plastic noses?" - Genghis Rex
