GeForce 810M vs GeForce GTS 150

Intro

Compare all of that to the GeForce GTS 150, which features GPU clock speed of 740 MHz, and 1024 MB of GDDR3 RAM set to run at 500 MHz through a 256-bit bus. It also is made up of 128 SPUs, 64 TAUs, and 16 ROPs.

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

Texel Rate

The GeForce GTS 150 should be much (approximately 702%) faster with regards to AF than the GeForce 810M. (explain)

GeForce GTS 150		47360 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 41456 (702%)

Pixel Rate

The GeForce GTS 150 will be much (about 301%) more effective at FSAA than the GeForce 810M, and should be able to handle higher screen resolutions better. (explain)

GeForce GTS 150		11840 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 8888 (301%)

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 information (counted in megabytes per second) that can be transferred past the external memory interface in a second. The number is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the 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 maximum number of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number 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 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.
