GeForce 830M vs GeForce GTX 950

Intro

Compare those specs to the GeForce GTX 950, which uses a 28 nm design. nVidia has set the core frequency at 1024 MHz. The GDDR5 memory runs at a speed of 1652 MHz on this specific card. It features 768 SPUs along with 48 TAUs and 32 ROPs.

GeForce 830M		25 Watts
GeForce GTX 950		90 Watts
	Difference: 65 Watts (260%)

Memory Bandwidth

As far as performance goes, the GeForce GTX 950 should in theory be much better than the GeForce 830M overall. (explain)

GeForce GTX 950		105728 MB/sec
GeForce 830M		14400 MB/sec
	Difference: 91328 (634%)

Texel Rate

The GeForce GTX 950 should be a lot (about 199%) faster with regards to texture filtering than the GeForce 830M. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce 830M		16464 Mtexels/sec
	Difference: 32688 (199%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce GTX 950 is the winner, by far. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce 830M		8232 Mpixels/sec
	Difference: 24536 (298%)

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 largest amount of information (in units of megabytes per second) that can be moved past the external memory interface in a second. It's worked out by multiplying the bus width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be applied per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
