GeForce 8800 GTX vs GeForce GTX 970M

Intro

The GeForce 8800 GTX uses a 90 nm design. nVidia has set the core speed at 575 MHz. The GDDR3 memory works at a frequency of 900 MHz on this model. It features 128 SPUs as well as 64 TAUs and 24 ROPs.

Compare those specifications to the GeForce GTX 970M, which uses a 28 nm design. nVidia has set the core frequency at 924 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this specific card. It features 1280 SPUs as well as 80 TAUs and 48 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the largest amount of information (measured in MB per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core 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 output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
