GeForce 830M vs Geforce GTX 760

Intro

Compare those specs to the Geforce GTX 760, which features a core clock frequency of 980 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 256-bit bus, and uses a 28 nm design. It is comprised of 1152 SPUs, 96 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M		25 Watts
Geforce GTX 760		170 Watts
	Difference: 145 Watts (580%)

Memory Bandwidth

The Geforce GTX 760, in theory, should be a lot faster than the GeForce 830M in general. (explain)

Geforce GTX 760		192256 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 177856 (1235%)

Texel Rate

The Geforce GTX 760 is a lot (approximately 471%) better at texture filtering than the GeForce 830M. (explain)

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

Pixel Rate

If using lots of anti-aliasing is important to you, then the Geforce GTX 760 is the winner, 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 information (counted in MB per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. If it uses DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster 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 number is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video 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 number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs 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 also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
