ATI's release schedule is proceeding as planned, with follow-ups to the Radeon 9600 Pro and 9800 Pro coming later this month and mid-to-late August.
So claim unnamed sources cited by Xbit Labs. The two upcoming chips are dubbed the RV350 and R360, respectively.
Further down the line, ATI is expected to unveil the R420 in November, in time for the Christmas sales season. It will be followed by a more mainstream version, the RV420. Both chips are believed to deliver next-generation pixel and vertex shader technology and DirectX 9.1 support.
R420 will almost certainly go up against Nvidia's anticipated NV40 chip, the company's first chip to be offered on PCI Express boards. NV40 is said to double the performance of the GeForce FX 5800, so R420 will need to offer a comparable leap over the Radeon 9800 Pro.
As previous Nvidia roadmap reports have suggested, the GeForce FX 5x00 line will be extended in the summer with the NV36 and the NV36X towards the end of the year. ®
