The next generation Xbox chip, the R500 will be ready as soon as the end of the first quarter of next year.
This chip comes as a derivatove of the R520 chip better known under its code name Fudo and will be of a similar architecture to the upcoming desktop chip. The only main difference will be an integrated frame buffer that you don’t see that often on desktop cards.
At this time, sources said the Xbox 2 development kit includes a 9800XT card and platform and you can only achieve five to 10 FPS with Xbox 2 working titles.
That’s why a full developer's kit will be available in late Q1 2005. This kit will include the flagship R500 chip that will give the right measure of graphics performance.
