ATI today announced HyperMemory, an innovative technology that reduces PC system costs by allowing its visual processors to use system memory for graphics processing. HyperMemory uses the high-speed bi-directional data transfer capabilities of PCI Express to store and access graphics data in system memory, leading to less of a dependence on graphics memory and ultimately a lower overall system cost.
Under previous interconnect standards, the data transfer between the visual processor and the CPU was not fast enough for real-time graphics applications, so graphics cards have shipped with up to 256 MB of dedicated graphics memory to store textures and rendering data required by the graphics processor. HyperMemory gives ATI and its board partners the option to deliver cards with less on-board memory and instead use system memory to handle the graphics storage requirements. The result is a lower overall PC cost for the same great graphics performance.
HyperMemory uses intelligent memory allocation algorithms to optimize the use of available local memory and ensure critical components are placed in fast local memory when required. Optimal assignment of data to local or system storage is determined dynamically to ensure the best user experience. HyperMemory also increases the performance of system bus data transfers, making accessing system memory faster than ever before.
