Future Promise for Graphics: PCI Express

Bridge It - NVIDIA's HSI Bridge

After ATi attacked its strategy at IDF using shirts with the slogan "GO NATIVE - PCI Express Done Right!" at IDF, NVIDIA is now defending its approach. There are some good arguments in favor of NVIDIA's plan. After all, a bridge isn't by definition a bad thing - consider that the northBRIDGE on your motherboard is also nothing more than a bridge...
