nv30 128bit mem "confirmed" ;)

Bandwidth was an essential performance aspect in current and last generation chips. Matrox's Parhelia came without any support for bandwidth saving features and suffered. Do you think more time should be spent on bandwidth savings then brute force bandwidth efforts? Matrox, 3D Labs, and ATI have all moved to 256bit architectures, does this signal a necessity to move towards 256bit? What do you think of DDRII?

In the past few generations of NVIDIA’s products, both bandwidth and computation affect performance. Overclocking either memory speed or core speed improves performance, so that means that sometimes rendering is limited by memory bandwidth, and other times rendering is limited by pipeline processing power. To truly move to the next level in terms of performance and features, we’ll need to increase both. A wider memory interface is one way to increase bandwidth, but there are other ways. As you mention, DDR2 is another way of building a higher throughput memory system. I think that DDR2 is going to be really exciting for the graphics community, since it brings the potential of more memory bandwidth per signal pin. This is a good trend, regardless of how many bits wide the datapath is!There are costs associated with both increasing the datapath width and increasing the computational core. If you look at the new programmable features on the OpenGL and DirectX, you’ll see that a lot more floating point math is required, which requires both bandwidth and computation growth. Both of these will be increased in the next generation. We’ll move to 256bit when we feel that the cost and performance balance is right.
