nVidia's HSI and PCI Express Plan Documentation

By: Cameron Wilmot | Editorials in Video Cards | Posted: Mar 23, 2004 5:00 am



Hopefully these slides and accompanying information have provided you with a better understanding on nVidia's PCI Express GPU plans and intentions for the near future. From what we can see on paper, the HSI bridge chip should do a good job at providing all the bandwidth the PCI Express 16x bus will require through nVidia's clever thinking.


It remains to be seen if native PCI Express parts from ATI and XGI and so on will perform better than the overclocked AGP16x products from nVidia but at this stage there is no evidence to suggest that might be the case.


Initially we thought nVidia might be at a disadvantage by employing the use of Hi-Speed Interconnect technology but they have put down a pretty good case (on paper!) with the benefits of providing existing AGP GPU parts into PCI Express and visa versa by later down the track providing pure PCI Express GPU parts back into AGP for those still with older motherboards who do not wish to upgrade their entire system. It makes a whole lot of sense since if you want to upgrade to a PCI Express supported motherboard in the coming months, chances are you will need to upgrade your CPU, memory and possibly ATX case to a BTX case and power supply.


I doubt anyone will be entirely certain until they have the actual products in their hands when we can all compare the difference in approaches to PCI Express employed by each company involved in the exciting bus transition.


Nevertheless in ending all these new technologies provide me with a type of technological warmth in my body which I haven't felt for a long time as we await a whole bunch of new technologies to hit the market. It is this new technology which renews my interest in the industry and should be considered a very good thing for everyone involved in the IT industry as the leading companies help spice life up for us all.
