GeForce 840M vs GeForce 930M

Intro

The GeForce 840M has a GPU core speed of 1029 MHz, and the 2048 MB of DDR3 memory runs at 1000 MHz through a 64-bit bus. It also is comprised of 384 SPUs, 24 Texture Address Units, and 8 Raster Operation Units.

Compare all that to the GeForce 930M, which has core speeds of 928 MHz on the GPU, and 900 MHz on the 2048 MB of DDR3 RAM. It features 384 SPUs as well as 24 Texture Address Units and 8 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
