GeForce 8800 GTS (G80) 320MB vs GeForce GTX 950

Intro

The GeForce 8800 GTS (G80) 320MB makes use of a 90 nm design. nVidia has clocked the core speed at 513 MHz. The GDDR3 RAM is set to run at a frequency of 792 MHz on this particular model. It features 96 SPUs along with 48 Texture Address Units and 20 Rasterization Operator Units.

Compare those specs to the GeForce GTX 950, which has core clock speeds of 1024 MHz on the GPU, and 1652 MHz on the 2048 MB of GDDR5 RAM. It features 768 SPUs along with 48 Texture Address Units and 32 ROPs.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
