Triangles per second is an indication that indicates the maximum drawing / representation per second!With a 1000 MHz GPU you can draw up to 1000 million triangles / sec. Assuming the graphics card shader is not under heavy load, you can easily achieve these numbers when all the triangles are calculated by the GPU. The speed of triangles / sec is reduced through extended rasterization or changing of the shaders (shadow units) as well as changing textures and uploading various shapes to the GPU. As an an example! An NVIDIA GTX 950 chip runs at 1 GHz and has 3 triangles per clock, so the GT 950 is likely to get 3 billion triangles per second, unless this is limited by some other criterion. The 980 GTX achieves a performance of 4,981 tera-flops with FP32 (float) The RTX 2080 achieves a performance of 13.45 tera-flops with FP32 (float) All factors in rendering are important!It plays a big role what is displayed, for example, whether the triangles are simply displayed in one color or with textures, if textures are used, the texture size also plays a role because there is a limit to the pixel rate and texture rate . The pixel rate and the texture rate of the GPU!The pixel fill rate refers to the number of pixels of a video card to the screen and writing in a video memory. The texture fill rate stands for the number of texture elements. More Triangles Per Second (TPS) Considerations! Triangles per second (TPS) is a measure of the performance of a graphics processing unit (GPU). This is the number of triangles a GPU can render per second. A triangle is the basic building block of 3D graphics, so TPS is a good indication of how well a GPU can handle complex 3D scenes. However, TPS is not the only factor that affects GPU performance. Other factors such as the complexity of the scene, the number of textures and the shaders used can also have a significant influence. In general, a higher TPS means the GPU can render more complex scenes more smoothly. However, it is important to note that TPS is just one metric and should not be used in isolation to determine the overall performance of a GPU. Here is a general indication of triangles per second for different types of applications: Simple 3D games: 100,000 to 1 million triangles per second Complex 3D games: 1 million to 10 million triangles per second CAD and professional 3D applications: 10 to 100 million triangles per second Virtual reality (VR) applications: 100 million to 1 billion triangles per second Modern GPUs can render billions of triangles per second, but most applications don't require that many triangles. Even demanding applications like VR games typically only require a few hundred million triangles per second. It's also important to note that TPS is not the only factor that affects a GPU's perceived performance. Other factors such as frame rate and latency can also have a significant impact.
