GeForce 8800 GT 512MB vs GeForce GTX 965M

Intro

The GeForce 8800 GT 512MB comes with a clock frequency of 600 MHz and a GDDR3 memory frequency of 900 MHz. It also features a 256-bit bus, and uses a 65 nm design. It features 112 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Compare those specs to the GeForce GTX 965M, which comes with GPU clock speed of 944 MHz, and 2048 MB of GDDR5 RAM running at 1000 MHz through a 128-bit bus. It also is comprised of 1024 Stream Processors, 64 TAUs, and 32 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of MB per second) that can be moved over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster 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 in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video 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 maximum amount of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
