Well, I'm not from Convex, but here is what I have gleaned from the press releases.... --------------------------------------------------------------------- C3200 series --- 1-4 processors -- 25 MHz clock. 200 MFLOPS peak performance (64-bit or 32-bit). This product is essentially the same as the old C200 series except that it has been redesigned to make use of the new fabrication techniques developed for the C3 series. The entry level price has dropped from ~$600,000 to $350,000. C3400 series --- 1-8 processors --- 50 MHz clock 800 MFLOPS peak performance (32-bit) 400 MFLOPS peak performance (64-bit) This product is the slow version of the new cpu. Unlike the C200 series (and apparently the C3200 series), these new machines run at double-speed on 32-bit floating-point numbers. Note that the vector pipe only runs at 50 MHz for 32-bit operands --- for 64-bit operands, it runs at the same rate as the C3200 series (and old C200's). C3800 series --- 1-8 processors --- 60 MHz clock 1920 MFLOPS peak performance (32-bit) 960 MFLOPS peak performance (64-bit) This is their new flagship, implemented in Gallium Arsenide technology. Price is $2 million to $8 million. Two machines (4 processors each) have already been sold to German and Danish Meteorological centers. -- John D.
