GeForce 830M vs Geforce GTX 760

Intro

Compare that to the Geforce GTX 760, which features clock speeds of 980 MHz on the GPU, and 1502 MHz on the 2048 MB of GDDR5 RAM. It features 1152 SPUs along with 96 TAUs and 32 ROPs.

GeForce 830M		14400 MB/sec
	Difference: 177856 (1235%)

Texel Rate

The Geforce GTX 760 should be quite a bit (about 471%) faster with regards to texture filtering than the GeForce 830M. (explain)

Geforce GTX 760		94080 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 77616 (471%)

Pixel Rate

If running with a high screen resolution is important to you, then the Geforce GTX 760 is a better choice, and very much so. (explain)

Geforce GTX 760		31360 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 23128 (281%)

Please note that the above 'benchmarks' are all just theoretical - the results were calculated based on the card's specifications, and real-world performance may (and probably will) vary at least a bit.

Specifications

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
