GeForce GTX 550 Ti vs GeForce GTX 950

Intro

The GeForce GTX 550 Ti has a GPU clock speed of 900 MHz, and the 1024 MB of GDDR5 memory is set to run at 1026 MHz through a 192-bit bus. It also features 192 SPUs, 32 TAUs, and 24 ROPs.

Compare all of that to the GeForce GTX 950, which comes with GPU core speed of 1024 MHz, and 2048 MB of GDDR5 RAM running at 1652 MHz through a 128-bit bus. It also is comprised of 768 SPUs, 48 TAUs, and 32 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
