GeForce 810M vs GeForce GTX Titan

Intro

Compare those specifications to the GeForce GTX Titan, which comes with a core clock speed of 837 MHz and a GDDR5 memory frequency of 1502 MHz. It also features a 384-bit bus, and makes use of a 28 nm design. It is comprised of 2688 SPUs, 224 TAUs, and 48 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GTX Titan		250 Watts
	Difference: 235 Watts (1567%)

Memory Bandwidth

In theory, the GeForce GTX Titan should be much faster than the GeForce 810M overall. (explain)

GeForce GTX Titan		288384 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 273984 (1903%)

Texel Rate

The GeForce GTX Titan should be quite a bit (more or less 3076%) better at anisotropic filtering than the GeForce 810M. (explain)

GeForce GTX Titan		187488 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 181584 (3076%)

Pixel Rate

The GeForce GTX Titan will be quite a bit (about 1261%) more effective at AA than the GeForce 810M, and also should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce GTX Titan		40176 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 37224 (1261%)

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 MB per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, it must be multiplied by 2 again. If 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 applied per second. This number is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
