GeForce 8800 GTS (G92) vs GeForce GTX 950

Intro

The GeForce 8800 GTS (G92) uses a 65 nm design. nVidia has clocked the core speed at 650 MHz. The GDDR3 RAM works at a speed of 970 MHz on this specific card. It features 128 SPUs along with 64 TAUs and 16 ROPs.

Compare those specifications to the GeForce GTX 950, which has a GPU core clock speed of 1024 MHz, and 2048 MB of GDDR5 RAM running at 1652 MHz through a 128-bit bus. It also is made up of 768 SPUs, 48 Texture Address Units, and 32 Raster Operation Units.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
