GeForce 810M vs GeForce GTX 260

Intro

Compare all of that to the GeForce GTX 260, which has a clock speed of 576 MHz and a GDDR3 memory frequency of 999 MHz. It also makes use of a 448-bit bus, and makes use of a 65 nm design. It is comprised of 192 SPUs, 64 Texture Address Units, and 28 Raster Operation Units.

GeForce 810M		15 Watts
GeForce GTX 260		182 Watts
	Difference: 167 Watts (1113%)

Memory Bandwidth

Theoretically, the GeForce GTX 260 should perform a lot faster than the GeForce 810M overall. (explain)

GeForce GTX 260		111888 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 97488 (677%)

Texel Rate

The GeForce GTX 260 will be quite a bit (about 524%) more effective at AF than the GeForce 810M. (explain)

GeForce GTX 260		36864 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 30960 (524%)

Pixel Rate

The GeForce GTX 260 should be quite a bit (approximately 446%) more effective at anti-aliasing than the GeForce 810M, and also should be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce GTX 260		16128 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 13176 (446%)

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 maximum amount of data (measured in megabytes per second) that can be transported across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling 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 could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs 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 output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
