Usually the final specification are locked at least 6-8 months before launch. If MS is planning to launch in November 2011 (which seems likely to happen), the final specification will be locked during Spring 2011. By that time, Ati should have their new architecture out. So Xbox Next could have a tuned version of N.I or an improved RV870. If they launch in Nov. 2012, Xbox Next will have for sure a N.I derivate.
Let's put one thing clear. Next-gen console won't be enough powerfull to have realtime radiosity. But all the assets that will be developed for next-gen games, will be of CGI quality: high-resolution texture, models, shader. And one thing that next-gen must focus on is image quality: i rather have a slighly less complex engine, but without aliasing at all, and with awesome post-processing effects. So there are two aress were MS/Sony/etc engineers have to wrap their mind around are:
- Huge amount of bandwidth
- High amount of memory
I think both eDRAM and fast streaming are the proper way to resolve them. It will be nice to see how MS and Sony will use different technology and ideas. :smile:
thank you very much, now i have a mental image of what may come next gen (esp cgi quality).
