The essential guide to IT transformation

Earlier this week, we reported some interesting facts about Nvidia's NV11, the follow-up to the GeForce 256. An Nvidia PR guy contacted us to confirm the accuracy of our earlier story. So now it's time to lift the veil on some more Nvidia secrets, which are also true. It's time to tell you something about the NV15 and - believe it or not - NV20. Here are the NV15's key features. It will have a 135MHz 3D core, 333MHz memory clock (obviously DDR), transfom and lighting set-up and rendering, a 256-bit rendering engine, a 540 million pixels per secound fill rate, and support up to 128MB RAM. In addition to T&L, the NV15 will offer a new feature called clipping. It will have two texture per pixel, four pixels pre-clock, memory flexibility, 128-bit SDR/DDR, 64-bit SDR/DDR, 96/48MB support (dissimilar memory sizes), an integrated single-link TMDS transmitter, support up to 1600x1200 panels. Cards based on the NV15 will use a VIP 2.0 port, the palette will have DAC/w Video overly and a digital interface for HDTV encoding. The NV15 will support both AGP and PCI buses. Based on 0.18 micron technology, it will pump out less than half the power dissipated by the GeForce 256 with which it will be 100 per cent software compatible. The NV15 should offer up to three times the performance of the GeForce. At teh same clock speed it will be faster than the GeForce, but when it's running athigher clock speeds, it will offer a two to three times improvement for multi–textured applications (like Quake III) and a 45 per cent improvement on T&L performance. Like NV11, NV15 will have dual display options such as VGA + TV out, VGA + LCD, VGA + VGA (with external DAC), LCD + TV out and LCD + LCD. It has memory flexibility and support for DDR/SDR swith 128, 96, 64, 32, 16 and 8MB frame buffers. As for the NV20, we know that the chip will be based on a massively complex architecture, containing more than 20 million transistors, and will be available at the end of 2000. NV20-based cards will be introduced six months after the NV15. It will be used in high-end systems for serious gamers and professionals (as the Quadro brand). ® Fuad Abazovic is the editor of the Bosnian IT magazine Info
