GeForce 930M vs Geforce GTX 780

Intro

The GeForce 930M features a GPU clock speed of 928 MHz, and the 2048 MB of DDR3 RAM runs at 900 MHz through a 64-bit bus. It also is made up of 384 SPUs, 24 TAUs, and 8 ROPs.

Compare those specifications to the Geforce GTX 780, which has clock speeds of 863 MHz on the GPU, and 1502 MHz on the 3072 MB of GDDR5 RAM. It features 2304 SPUs as well as 192 TAUs and 48 Rasterization Operator Units.

Memory Bandwidth: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better this number, the better the graphics 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 most pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
