Dat doe ik wel voor hem.
Ik citeer uit interview met Dave Orton:
"Sampsa: Can you tell us a little about the problems which you encountered when you moved to 90nm production technology?
Dave: "Xbox 360-game console’s Xenon-graphics chipset was developed on 90 nm with tremendous success, so we felt confident using it for the R5xx family. RV515, which will be aimed at the entry-level PC segment, also worked perfectly from the outset without encountering any manufacturing issues. But to be honest, we’ve had our share of challenges with the R520 and RV530 chips. Even though all the simulations that were done with the chips were looking good, there were still issues with the silicon when it came back from the fab. It was also surprising that RV515 and RV530 were designed by the same team and manufactured in the same fab using same technology, but RV515 worked perfectly and RV530 caused us problems".
According to Dave, R520 chips taped-out in November 2004 and original plan was to announce it seven to eight months later during the June-July period. Adopting smaller manufacturing technology delayed the schedule by a couple of months, but because of other challenges the engineers faced, the chips were delayed by an additional 2-3 months."
In feite kwam ATI onverwachte problemen tegen, wat goed te maken kan hebben met TSMC zelve.
Nog meer info:
"Sampsa: Last year when ATI moved from the 130nm to the 110nm manufacturing process, only the entry-level, mainstream and upper-mainstream products made the migration. How come this time around you’re using the latest process technology, 90nm, for your entire product family, including high end?
Dave: "One major factor relating to adoption of smaller manufacturing technology was naturally our deal with Microsoft on the graphics solution of Xbox360, and the success of the Xenos graphics processor has given us a high confidence level in the 90nm process. And although there have been challenges along the way, recent results with the R520 and RV530 are looking excellent, and indicate that they'll be very well placed in the market in terms of both performance and image quality when they arrive in the fall.""
Dave Orton geeft nVidia ook credit voor zijn SLI, maar:
"Sampsa: Would it then be fair to say that you launched CrossFire because of pressure from Nvidia?
Dave: "Nvidia certainly deserves credit for bringing SLi to the market and generating more consumer interest in multi-card solutions, but the vision behind CrossFire was to create the only multi-card solution on the market that provides a performance or image quality improvement to 100% of 3D games, not just 2 or 3%. Delivering a solution with 30X the level of game compatibility means a longer engineering investment, and the feedback we’ve received from customers is that they are prepared to wait a bit longer for a solution that meets their needs better"."
