The debut of video accelerators compatible with the DirectX 10 API took place on November 9, 2006. At that time, it was the only series of video cards that could boast of such capabilities. We are talking about Hi-End video accelerators NVIDIA GeForce 8800 GTX and NVIDIA GeForce 8800 GTS. The first was built on the basis of a graphics chip codenamed G80 and had 768 MB of video memory on board, while the second was a more stripped-down version of the same G80 and had 640 MB of memory. These solutions were quite expensive and many users couldn't afford it, so NVIDIA decided to release an even more stripped-down version of the GeForce 8800 GTS, namely, a video card with exactly the same characteristics, but with less video memory - 320 MB. The official announcement of NVIDIA GeForce 8800 GTS 320 MB took place on February 12, 2007. Since then, DirectX 10 has become even closer to the people. It's a pity, but at that time there were very few games, just like now, that fully implement all the technological capabilities of DirectX 10.

We will consider its main unified architecture based on the GeForce 8800 GTX video card, since the junior GeForce 8800 GTS is, as we have already said, only a "cut" of the older GTX. The heart of the video adapter consists of 681 (!!!) million transistors (the G70 had about 300 million of them), which immediately affected the area of the crystal upwards. "Monster" operates at 575 MHz for NVIDIA GeForce 8800 GTX and at 500 MHz for NVIDIA GeForce 8800 GTS. The GPU uses a unified shader architecture that the company has pioneered. The idea of unifying GPU functional blocks is as follows: previously they were divided into vertex and shader ones, and now universal blocks are able to process any kind of instructions without significant performance losses. This will allow you to dynamically change the performance of the kernel by reallocating resources to the task that is currently needed. As a result, we get a full load of the chip and, as a result, performance increases.

The number of unified pipelines has decreased from 128 to 96, in general, the performance of these cards is still at a good level even now.
