What is Hybrid solutions concerning symbolic cards?

This newer class of GPU's competes beside integrated graphics in the low-end PC and notebook market. The most common implementations of this are ATi's HyperMemory and nVidia's TurboCache. Hybrid graphics cards are somewhat more expensive than integrated graphics, but much smaller quantity expensive than dedicated graphics cards. These also share memory next to the system memory, but have a smaller amount of memory on-board than discrete graphics cards do to generate up for the high latency of the system RAM. Technologies inside PCI Express can make this possible. While these solutions are sometimes advertise as having as much as 512MB of RAM, this refers to how much can be shared near the system memory.
