The NV40 code-named chip is scheduled to come this year, but no one knows when exactly it will be available. Some believe that in Fall, some other say by Christmas. The high-end VPU will consist of 150 million transistors and will be made using 0.13 micron fabrication process. Compared to 125 million of the NV30 (GeForce FX) the code-named NV40 does not seem to be something brand-new, but a very-well improved GeForce FX.
NVIDIA’s code-named NV35 graphics chip should be available this Summer. It will implement 130 million of transistors, just a little bit more than its unlucky predecessor. No precise ideas about possible improvements.
There will be three flavours of the NV31 graphics processor that will be unveiled at CeBIT 2003 in March and will be intended to substitute the GeForce Titanium series on the performance-mainstream market. All the babes feature 80 million of transistors (about 65 million is utilised in the GeForce4 Ti) and 4 rendering pipelines. Note that they are already taped-out. The only difference between the chips will be in their clock-speeds for core and memory. VPUs will run at 350, 300 and 250MHz, while the memory clocking are to be determined. It is estimated that the higher-end version will be supplied with 650MHz memory, while the lower-end aka NV31-Mobile will be equipped with 500MHz DDR SDRAM memory.
The number of NV34 versions is going to be huge: from three to six maybe (four is the current estimation). NVIDIA may even allow some of its partners to clock the graphics cards according to their vision of the market and clients’ requirements. It is said that the chip contains 45 million of transistors and features 4 rendering pipes. The VPU will run at 300 to 375MHz, according to preliminary information. I wonder if there are going to be any NV34 derivatives specially developed for integration into NVIDIA’s next-generation nForce IGPs since 45 million of transistors is too lot for a graphics core integrated into a North Bridge
