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

Intro

The GeForce 8800 GTS (G80) 320MB features a clock speed of 513 MHz and a GDDR3 memory speed of 792 MHz. It also features a 320-bit memory bus, and makes use of a 90 nm design. It is comprised of 96 SPUs, 48 Texture Address Units, and 20 ROPs.

Compare all of that to the GeForce GTX 950M, which makes use of a 28 nm design. nVidia has set the core frequency at 914 MHz. The DDR3 RAM works at a frequency of 1000 MHz on this particular card. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the 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 amount of pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
