NVIDIA GeForce 6200 with TurboCache

The main advantage of NVIDIA's TurboCache technology, is that it eliminates the need for large amounts of local memory to store render targets such as back buffers, depth or stencil buffers, environment mapping textures, or other graphics data. By eliminating the need for large amounts of local memory, NVIDIA is able to reduce the overall cost of the board, because fewer discreet memory chips are used. This normally would sound like a disadvantage, but with the relatively large amount of bandwidth offered by a PCI Express X16 graphics link, performance isn't impacted as much by rendering directly to system memory.

NVIDIA's TurboCache implementation also eliminates a performance bottleneck usually associated with some other integrated graphics solutions, like the one found in Intel i915G, for example. Most integrated graphics processors are completely dependent on system memory. This means that they'll usually require more system memory for graphics use than a GeForce 6200 with TurboCache. And it's this use of system memory, and arbitrating for it, that causes system performance degradation when using most integrated graphics solutions. NVIDIA's GeForce 6200 with TurboCache, however, doesn't hurt overall system performance because it has some local memory and it intelligently manages its use of system memory. When installed in the very same system, the GeForce 6200 with TurboCache actually increases overall performance in a variety of popular benchmarks when compared to Intel's integrated graphics.
