GeForce 830M vs GeForce GTX 960

Intro

Compare all that to the GeForce GTX 960, which comes with GPU core speed of 1127 MHz, and 2048 MB of GDDR5 memory running at 1750 MHz through a 128-bit bus. It also is comprised of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

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

Memory Bandwidth

Performance-wise, the GeForce GTX 960 should theoretically be quite a bit superior to the GeForce 830M overall. (explain)

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

Texel Rate

The GeForce GTX 960 is quite a bit (more or less 338%) faster with regards to anisotropic filtering than the GeForce 830M. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 960 is superior to the GeForce 830M, by far. (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 maximum amount of information (counted in MB per second) that can be transported over the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This figure is worked out by multiplying the total texture units of the card 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 one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could 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 ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
