The release of the Microsoft Xbox 360 will be driving performance of ATI and SiS in the fourth quarter of this year. Foundry service providers for ATI and SiS, TSMC and UMC will likely benefit from the huge demand for the game console that three million units will be sold worldwide in the first three months of launch. ATI places graphics processor foundry orders for the Xbox 360 with TSMC at the foundry’s 12-inch fab on 90nm production node. SiS is the sole southbridge supplier for the game console, with the chips mainly being manufactured at UMC’s eight-inch fabs on the 0.15-micron node.
