If you look around at the notebook market today you will possibly find a solution which features a so called Mobility Radeon X2300 graphics chip. If you think about it this is something odd, the whole R600 aka X2K series is still be announced. Though the XbitLabs reported about one of these (the Asus A8Jr laptop) this January already. Today TheInquirer sheds some light onto the situation. It seems like AMD/ATI are mixing up the brand names of different chip generations. This former mentioned X2300 Mobility chip is in fact a rebranded X1300 chip, so nothing really fast and nowhere near sporting enough to be named in line with the R600 stuff.
