GeForce 810M vs GeForce GTX 950M

Intro

Compare those specifications to the GeForce GTX 950M, which uses a 28 nm design. nVidia has clocked the core speed at 914 MHz. The DDR3 RAM is set to run at a speed of 1000 MHz on this model. It features 640 SPUs as well as 40 TAUs and 16 ROPs.

GeForce 810M		14400 MB/sec
	Difference: 17600 (122%)

Texel Rate

The GeForce GTX 950M will be quite a bit (more or less 519%) faster with regards to AF than the GeForce 810M. (explain)

GeForce GTX 950M		36560 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 30656 (519%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce GTX 950M is a better choice, by a large margin. (explain)

GeForce GTX 950M		14624 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 11672 (395%)

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 largest amount of data (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 per second. This is calculated by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. 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 fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
