Graphics drivers have been doing this for some time already with the AGP bus and even the initial PCIe cards, but NVIDIA’s TurboCache technology extends the functionality to include renderable surfaces and writing to them. The memory is allocated and released on demand meaning that no memory is statically locked down as is the case with most integrated graphics solutions. Using standard Microsoft approved methods for memory allocation, idle pages of system memory are used and mapped on demand as the driver determines they are needed. The memory buffer that is stored in main memory is controlled and maintained by the graphics driver. The memory allocation process on the 6200TC is pretty straight-forward process. TC has the ability to render to and from system memory efficiently, the ability to texture from system memory as well as the ability to dynamically allocate and de-allocate system memory for its use. TurboCache is an NVIDIA solution that allows you to utilize system memory as a graphics buffer in much improved fashion thanks to PCI Express. NVIDIA’s TurboCache, utilizing the high bandwidth of the PCI Express bus, is able overcome that obstacle. This makes recent trends/effects in gaming technology, like rendering to textures, very slow because of a basically one-way AGP bus. The AGP bus was the first attempt by the industry to try and alleviate this issue, but the AGP bus was not designed for writing memory across the bus, only reading. This forced the card vendors to use larger amount of local graphics memory thereby raising costs for the end user. For the majority of graphics solutions, render surfaces (such as environment mappings and stencil buffers) are located in local memory on the graphcs card. NVIDIA wants to bring the majority of their 6000-series features down below the 0 price range into the entry level market but with a card with only a 32MB frame buffer?īefore discussing TurboCache, we need to understand the problem with “traditional” graphics subsystems.
