GeForce 810M vs GeForce GTX 980M

Intro

Compare those specifications to the GeForce GTX 980M, which features a GPU core clock speed of 1038 MHz, and 4096 MB of GDDR5 RAM running at 1000 MHz through a 256-bit bus. It also is comprised of 1536 SPUs, 96 TAUs, and 64 Raster Operation Units.

GeForce 810M		14400 MB/sec
	Difference: 113600 (789%)

Texel Rate

The GeForce GTX 980M should be much (about 1588%) better at AF than the GeForce 810M. (explain)

GeForce GTX 980M		99648 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 93744 (1588%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce GTX 980M is superior to the GeForce 810M, by a large margin. (explain)

GeForce GTX 980M		66432 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 63480 (2150%)

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 (measured in MB per second) that can be moved across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better 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 applied in one second. This is worked out by multiplying the total texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
