GeForce 6200

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

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

Even with the use of system memory via PCI Express, all 6200 TC models suffered primarily from a lack of memory bandwidth, both system and local. The 6200 TC's peak fill rate was 700 megapixels, while local memory bandwidth is more than half that, and that's before 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 large resolutions and modes with full-screen anti-aliasing, especially in simple applications, and the strong point was programs with long and complex shaders and anisotropic filtering without simultaneous MSAA.

Varieties of GeForce 6200 cards implemented Turbo Cache Technology, GeForce 6200TC - this was the final chord in the GeForce 6 line for PCI-E, a card with all the characteristics of the NV6200-based 43, with the only but significant difference - it carried on board all 16 Mb of video memory, making up for the “shortage” of local memory from system memory, with the ability to use up to half of the installed system memory.

In general, we can say that the GeForce 6200 was a worthy product in the GeForce 6 line for the low-end sector, with a good combination of price and performance and good overclocking potential.
