The Geforce 9400 was the same card as the 8500, but on a new media, and with Turbocache added. nVIDIA had already decided on continuing to increase the size and complexity of its high end GPUs, which greatly inhibits the development of lower powered cards out of the new designs, and the 8600 GT had really been too costly to compete with the Radeon HD 3650, so they cut it in half, roughly, making the result quite a bit better than the 8400. It was marketed as a Budget graphics card, but wasn't very good at what it was supposed to do. It wasn't until the GT 220 that they got the fence-straddling spot locked down (more or less where the GT 440 is now).
Transferred to laptops, the 8500 and 9400 took another performance cut, which is why they need low settings in screen resolutions.
