GeForce 930M vs Geforce GTX 780

Intro

The GeForce 930M makes use of a 28 nm design. nVidia has set the core frequency at 928 MHz. The DDR3 memory runs at a frequency of 900 MHz on this model. It features 384 SPUs as well as 24 TAUs and 8 ROPs.

Compare those specifications to the Geforce GTX 780, which uses a 28 nm design. nVidia has set the core frequency at 863 MHz. The GDDR5 memory is set to run at a frequency of 1502 MHz on this model. It features 2304 SPUs along with 192 TAUs and 48 ROPs.

Memory Bandwidth: Bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 figure is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core 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 rate is also dependant on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
