The value-end video card segment in the past employed a mixed product status. GPUs of the past under $100 were stripped down in features. This practice dates back quite a while and the most famous example of this was the GeForce4 MX series which stripped the features of a programmable pixel and vertex shader that its bigger brother the GeForce4 Ti series had. Another recent example of this is the GeForce 6200 series of the last generation which stripped FP 16 HDR framebuffer support and Z compression support.
