It's the opposite of the unified bus approach - something done to save on cost not for the sake of performance. Rather than GPU access to dynamically allocated video and system RAM competing for bandwidth on the same bus as the CPU uses to access system RAM, each of these have their own high-bandwidth bus. Fewer bottlenecks as they don't have to compete for memory access.
