GeForce 8800 Ultra vs GeForce GTX 970M

Intro

The GeForce 8800 Ultra comes with core speeds of 612 MHz on the GPU, and 1080 MHz on the 768 MB of GDDR3 RAM. It features 128 SPUs as well as 64 TAUs and 24 Rasterization Operator Units.

Compare all that to the GeForce GTX 970M, which has GPU clock speed of 924 MHz, and 3072 MB of GDDR5 memory set to run at 1000 MHz through a 192-bit bus. It also is comprised of 1280 Stream Processors, 80 Texture Address Units, and 48 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the bus width by its memory clock speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high 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 this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
