GeForce 9500 GT DDR2 vs GeForce GTX 870M

Intro

The GeForce 9500 GT DDR2 features a GPU core clock speed of 550 MHz, and the 256 MB of DDR2 memory is set to run at 500 MHz through a 128-bit bus. It also is made up of 32 SPUs, 16 Texture Address Units, and 8 ROPs.

Compare all that to the GeForce GTX 870M, which has GPU clock speed of 941 MHz, and 3072 MB of GDDR5 memory running at 1000 MHz through a 192-bit bus. It also features 1344 SPUs, 112 TAUs, and 24 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of information (counted in MB per second) that can be transferred across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
