slight correction, the Intel i740 is not a derivative of Real3D/Pro-1000. it was a freshly designed chip by Intel, Real3D and Chips & Technologies. it was a very low-cost chip in 1998, that could barely compete with Voodoo2, and was closer in performance to a Voodoo1, even though i740 was higher quality in features. i740 in practice was not even as good as the old pre-Real3D Martin Marietta/Fujitsu Model2 board. i740 had no geometry processor of its own, unlike Model 2 which had the Fujitsu DSPs and Model 3 which had geometry processors inside the Real3D/Pro-1000 GPUs.

In short, the i740 did use Real3D technologies, but not specifically a derivative of the Real3D/Pro-1000 used in Model 3. the analogy would be: General Motors: they make an older 1995 Corvette and a newer 1997 Chevy Cavolier. both cars use GM technologies, but one is far cheaper and has less performance than the other. the older higher-end car outperforms the newer lower-end car.
