X-Bit Labs have an interesting article posted derived from a few words said over at AnandTech by Anand suggesting that nVidia will launch two new GeForce4 Ti graphics cards later this year - The Ti4800 (essentially Ti4600 with AGP8x) and TI4800SE (essentially Ti4400 with AGP8x). The naming conventions are a little misleading and X-Bit Labs tend to agree.
Apparently, NVIDIA will soon launch two new GeForce4 Titanium graphics processors this year. According to the source, one will be called the GeForce4 Ti4800 and another - the GeForce4 Ti4800SE. The first will represent the GeForce4 Ti4600 with AGP 8x support, while the remaining will be the GeForce4 Ti4400 with AGP 8x protocol.More information @ X-Bit Labs
