GeForce 830M vs GeForce GTX 960

Intro

Compare that to the GeForce GTX 960, which features a core clock frequency of 1127 MHz and a GDDR5 memory frequency of 1750 MHz. It also uses a 128-bit bus, and uses a 28 nm design. It features 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 830M		25 Watts
GeForce GTX 960		120 Watts
	Difference: 95 Watts (380%)

Memory Bandwidth

In theory, the GeForce GTX 960 should be 678% faster than the GeForce 830M in general, due to its greater bandwidth. (explain)

GeForce GTX 960		112000 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 97600 (678%)

Texel Rate

The GeForce GTX 960 is a lot (approximately 338%) better at AF than the GeForce 830M. (explain)

GeForce GTX 960		72128 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 55664 (338%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 960 is a better choice, and very much so. (explain)

GeForce GTX 960		36064 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 27832 (338%)

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: Bandwidth is the max amount of information (in units of megabytes per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
