GeForce 810M vs GeForce GTX 950

Intro

Compare those specifications to the GeForce GTX 950, which features a GPU core clock speed of 1024 MHz, and 2048 MB of GDDR5 memory running at 1652 MHz through a 128-bit bus. It also is made up of 768 Stream Processors, 48 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GTX 950		90 Watts
	Difference: 75 Watts (500%)

Memory Bandwidth

In theory, the GeForce GTX 950 should be 634% faster than the GeForce 810M in general, because of its greater bandwidth. (explain)

GeForce GTX 950		105728 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 91328 (634%)

Texel Rate

The GeForce GTX 950 will be much (more or less 733%) more effective at anisotropic filtering than the GeForce 810M. (explain)

GeForce GTX 950		49152 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 43248 (733%)

Pixel Rate

The GeForce GTX 950 should be quite a bit (approximately 1010%) better at AA than the GeForce 810M, and will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX 950		32768 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 29816 (1010%)

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 data (measured in MB per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out 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 rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
