ATI plans to introduce its brand new R520 technology exactly a year after it announced its R420. Despite the news that ATI might even be ready with R520 for CeBIT, it seems that the company wants to hold its breath and try to release the silicon in May.
We already said that the R520 taped out and our sources confirm that the chip is in good shape, but then again it's still the first working silicon that it got out of the fab. It takes at least six weeks to get the next revision of silicon. This means that ATI is still on track and will possibly make one more revision before it goes to final production.
