NV18 & NV28 : NVIDIA Chips with AGP-8x Flavor

As expected, AGP 8x can safely be considered a marketing feature for now. Although it sounds impressive, it offers no real benefit for the current generation of games. A GPU like the GeForce4 MX440 would be unable to handle the amount of data the 8x interface is capable of supplying anyway, and it would be much slower than the on-board memory as well.

The most telling sign that the switch to AGP 8x is more of a calculated marketing move than a push for desperately needed hardware resources is the fact that the only two NVIDIA cards that are being "upgraded" to the new interface are also the company's mainstream cards, the best sellers MX440 and Ti4200, while the heavyweights Ti4400 and Ti4600 remain unchanged.
