HyperMemory

thumb|HyperMemory HyperMemory was a brand for ATI's method of using the motherboard's main system RAM as part of or all of the video card's video memory on their line of Radeon video cards and motherboard chipsets. It relies on new fast data transfer mechanisms within PCI Express.

However, to make up for the inevitably slower system RAM with a video card, a small high-bandwidth local framebuffer is usually added to the video card itself. This can be noted by the one or two small RAM chips on these cards, which usually have a 32-bit or 64-bit bus to the GPU. This small local memory caches the most often needed data for quicker access, somewhat remedying the inherently high-latency connection to system RAM.
