techreport had a few articles where the same author contradicted himself. in the gf3 review, he says that gf3 keeps the fixed-function unit from gf2: https://techreport.com/review/2515/nvidia-gef … cs-processor/11
in the radeon 8500 review, he says that the gf3 implements the fixed-function unit as vertex shaders, while the radeon 8500 kept the legacy unit: https://techreport.com/review/3203/radeon-850 … force3-ti-500/2

which is true?
