Thanks to Mackey D for pionting out theses two article over at Xbitlabs called ATI R420 and NVIDIA NV40 Presumably Taped Out and Matrox Graphics Prepares PCI Express x16 Graphics Processor ! that's worth checking out! Here's a snip.
ATI has two high-end graphics chips in its roadmap for the first half of they year: R420 and R423. The former is designed for AGP 8x, the latter is developed for PCI Express x16. Other specs of both chips are supposed to be the same. NVIDIA has only one high-end chip for the 1H of the year ? the code-named NV40. It is not fully clear whether this is an AGP 8x or PEG x16 part, but even in case it is engineered for AGP 8x, NVIDIA still can address the PCI Express market with it, as the company has a special PEG x16 to AGP 8x bridge.
