HKEPC says NVIDIA will launch GeForce 7 cards with TurboCache to meet the harsh graphics requirements for Windows Vista Premium on its budget cards.
TurboCache is an old technology which has been introduced in Geforce 6 family, Geforce 6200 TurboCache, code name NV44, for sample. By the use of PCI-Express x16 bandwidth, the GPU can share some of the system memory, reducing the size of memory equipped in the card and hence its cost. It was a great idea, yet PCI-E was not common at that time and there was not crying need for a cheap upgrade, it was dead very soon, and TurboCache is almost forgotten.
The upcoming Windows Vista initializes the wave in system upgrade, and graphic of course. In order to making old and weak IGP products to be ready for Windows Vista, nVidia make TurboCache returns in Geforce 7 family. Using G72 core as Geforce 7300 (4PS 3VS/64Bit), the first product targets to ATi Radeon X1300CE (RV505, 4PS 2VS/64Bit) in the value level.
