GeForce 810M vs GeForce GTX 965M

Intro

Compare all of that to the GeForce GTX 965M, which comes with GPU clock speed of 944 MHz, and 2048 MB of GDDR5 RAM set to run at 1000 MHz through a 128-bit bus. It also features 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

GeForce 810M		14400 MB/sec
	Difference: 49600 (344%)

Texel Rate

The GeForce GTX 965M will be quite a bit (about 923%) better at texture filtering than the GeForce 810M. (explain)

GeForce GTX 965M		60416 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 54512 (923%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce GTX 965M is a better choice, by a large margin. (explain)

GeForce GTX 965M		30208 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 27256 (923%)

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 (counted in megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the interface width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This figure is worked out by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
