What we see [in the picture] appears to be nVidia's first native PCI Express NV40 graphics processor. While we knew nVidia would eventually transition the 6800 series to work on a PCI Express connection without the need to use an HSI chip, we were surprised to see that this chip is actually shipping to market. The physical dimensions of the core are identical to that of nVidia's NV40 AGP variant, but the chip itself does not have any need for any bridge chips to connect to a PCI Express bus. Unfortunately, we can’t be sure if this is a “true” native PCI Express chip or if nVidia embedded the HSI logic within the core itself. Looking at the dimensions of the core, it would appear though that this is indeed a native PCI Express component.
