JU, Re -- We talk about the technologies. OK. Talk about technologies, and why the yield problem is not fixed. Do you understand why? Stockman

James, thanks, on the subject of technology, December Byte has details on AMD K6-3D and K6+3D, in an article Beyond MMX -- AMD, Cyrix, and Centaur are adding new extensions for 3-D graphics to the x86 architecture -- without Intel's blessing. Will they split the Wintel PC standard? To answer that question, they say , "The good news is that Microsoft is modifying Direct3D to support the extensions from AMD, CYrix, and Centaur. That should prevent the Wintel PC standard from shattering -- for now." Here's some info from the article: 1. Timetable K6-3D will appear Q1'98. K6+3D in Q3'98. Intel's Pentium II with MMX2 extensions will not appear until late '98 /early '99. ('Katmai') 2. CPU features K6-3D will have 100MHz bus, superscaler MMX with lower latency than Intel, 3D instruction set. The 3D instructions are processed in a completely separate 3D FPU with more than one multiply-accumulate (MAC) per clock cycle. BTW, MAC's are by far the most important operation involved in 3D graphics, and the K6-3D will do MAC's four times faster than a Pentium II at the same clock speed. "The K6-3D core speed should soar to 300 MHz and higher." Other than even higher clock speeds and built in 256K L2 cache with backside bus, its not clear what the "+3D" model in 3Q'98 will bring to the table. As for Centaur (IDT) and Cyrix, they say that the 3D version of the Centaur C6 will be called the C3A and will appear March-April of '98, while the 3D Cyrix Cayenne will appear "2nd half" of '98. This is from the December issue of Byte on sale at your newstand now. There's also an article about the IA-64 Merced architecture. Petz
