GeForce 940M vs GeForce GTX 960

Intro

The GeForce 940M comes with a clock speed of 1072 MHz and a DDR3 memory speed of 1000 MHz. It also features a 64-bit memory bus, and makes use of a 28 nm design. It is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Compare those specifications to the GeForce GTX 960, which features GPU core speed of 1127 MHz, and 2048 MB of GDDR5 RAM set to run at 1750 MHz through a 128-bit bus. It also features 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of data (in units of MB per second) that can be transported across the external memory interface within a second. The number is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the video card will be at 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 the video card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
