GeForce GTX 950 vs GeForce GTX 980M

Intro

The GeForce GTX 950 features a GPU core speed of 1024 MHz, and the 2048 MB of GDDR5 RAM runs at 1652 MHz through a 128-bit bus. It also is comprised of 768 Stream Processors, 48 TAUs, and 32 ROPs.

Compare those specifications to the GeForce GTX 980M, which features GPU core speed of 1038 MHz, and 4096 MB of GDDR5 RAM set to run at 1000 MHz through a 256-bit bus. It also is comprised of 1536 Stream Processors, 96 Texture Address Units, and 64 ROPs.

Memory Bandwidth: Bandwidth is the largest amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the clock 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
