GeForce 6200

There were no global architectural differences from NV40 and NV43. In general, NV44 was a scaled (by reducing the number of vertex and pixel processors and memory controller channels) solution based on the NV40 architecture. The differences are quantitative (highlighted in bold on the diagram), but not qualitative - from the point of view of architecture, the chip has not changed much.

So, there are 3 vertex processors, like in NV43, and one (there were two) independent pixel processors working with one quad (2x2 pixel fragment). PCI Express became native, just like in the case of NV43 and (i.e. implemented on a chip), the very idea of ​​efficient use of system memory for rendering required adequate graphics bus bandwidth in both directions.

Even taking into account the use of system memory via PCI Express, all 6200 TC models primarily suffered from a lack of memory bandwidth, both system and local. The peak fill rate of the 6200 TC was 700 megapixels, while the local memory bandwidth was more than half that, and that's without taking into account potentially reduced caches and a dual-channel memory controller.

The weak point of the 6200 TC family, as in the case of the 6600, was high resolutions and modes with full-screen anti-aliasing, especially in simple applications, but the strong point was programs with long and complex shaders and anisotropic filtering without simultaneous MSAA.

Turbo Cache Technology was implemented in the varieties of GeForce 6200 cards, GeForce 6200TC was the final chord in the GeForce 6 line for PCI-E, a card that has all the characteristics of the 6200 based on NV43, with the only but significant difference - it carried everything 16 Mb of video memory, making up for the "lack" of local memory from the system memory, with the possibility of using up to half of the installed system memory.
