Therin: I can answer your questions: <<1. When is the latest approximate shipping date for the K6-3D chip?>> June is when AMD will debut the K6-3D. I am not sure the exact date. <<2. Is the 3D chip going to made at .35 micron first and then at .25 micron later, or will it debut at .25 ? Also at what speeds are the cpus expected?>> According to sources, the K6-3D will be manufactured on 0.25um, none on 0.35um. The released speed is 300MHz and 350MHz on 100MHz bus speed of Super Socket 7. <<3. How will the 3D chip work with existing 3d graphics cards? Or is it one or the other? Either the software uses code written with the 3d MMX extensions or code written for the 3d chipset of the graphics card, but not both at the same time. Is this correct? >> If you play old games there is no performance improvement since the old softwares do not utilize the 3D MMX extension of the CPU. The 3D graphic card will do everything. If you play new games written for K6-3D the softwares will access the 3D MMX often and improve performance. The 3D graphic accelerator also improve the speed as well. Thus you have 2 engines doing 3D, in theory. We'll have to wait till the actual chip comes out and play the games to get the benchmark. << It is my understanding that both .35 and .25 micron cpus are currently being produced, until all the Fabs are converted to .25 micron. What marking or lettering is placed on the .25 cpu to that tell everyone that this is indeed a .25 micron cpu ?>> 0.35um K6 runs at voltage 3.2/3.3V. 0.25um K6 runs at 2.0 to 2.2V. If you don't know what this mean, then just remember the followings: Desktop K6 CPUs that are rated at 166, 200, and 233 are 0.35um. Mobile CPUs such as 233, 266, and 300 are 0.25um. Destop K6 of 266 and beyond are 0.25um. Maxwell
