GeForce 830M vs GeForce GTX 950

Intro

Compare all that to the GeForce GTX 950, which features a clock speed of 1024 MHz and a GDDR5 memory frequency of 1652 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It features 768 SPUs, 48 Texture Address Units, and 32 ROPs.

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

Texel Rate

The GeForce GTX 950 should be much (about 199%) better at anisotropic filtering than the GeForce 830M. (explain)

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

Pixel Rate

If using a high resolution is important to you, then the GeForce GTX 950 is the winner, and very much so. (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: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, 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 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 card will be at 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 that the graphics card can possibly record to its local memory per 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 speed of the card. ROPs (Raster Operations Pipelines - aka 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, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
