Richardson, Texas-based Cyrix Corp, which causes Intel Corp such problems by trumping all its maths co-processor aces, has expanded its FasMath line with two parts offering faster clock speeds – a 40MHz 83D87-40 for use with 32-bit bus 80386s, complementing 16MHz, 20MHz, 25MHz and 33MHz versions, and the 25MHz FasMath 83S87-for use with 80386SX 16-bit bus parts, for which the company already has 16MHz and 20MHz versions. The company claims that FasMath processors offer 5.5 MFLOPS peak performance and are pin and software compatible with Intel’s parts. The design is claimed to execute floating point maths operations up to 10 times faster while consuming one-third the power and providing more accurate results when compared with the Intel 80387 maths co-processors. The company has also reduced its prices so that the FasMath 83D87-16 is now $513; the 83D87-20 is $582; the 83D87-25 is $732; the 83D87-33 is $894; and the new 83D87-40 is $1,075; the 83S87-16 is $481; the 83S87-20 is $528; and the new 83S87-25 is $600. All products are available immediately, the company affirms.
