GeForce 920M vs GeForce 940M

Intro

The GeForce 920M features a GPU core speed of 954 MHz, and the 2048 MB of DDR3 RAM runs at 900 MHz through a 64-bit bus. It also features 384 Stream Processors, 32 TAUs, and 8 ROPs.

Compare those specifications to the GeForce 940M, which features GPU clock speed of 1072 MHz, and 2048 MB of DDR3 RAM running at 1000 MHz through a 64-bit bus. It also features 384 Stream Processors, 24 TAUs, and 8 Raster Operation Units.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better 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 amount of texture map elements (texels) that can be processed in one 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. 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 maximum fill rate.
