GeForce 810M vs GeForce GTX 280

Intro

Compare those specifications to the GeForce GTX 280, which uses a 65 nm design. nVidia has set the core frequency at 602 MHz. The GDDR3 memory works at a frequency of 1107 MHz on this specific card. It features 240 SPUs as well as 80 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GTX 280		236 Watts
	Difference: 221 Watts (1473%)

Memory Bandwidth

Theoretically speaking, the GeForce GTX 280 is 884% quicker than the GeForce 810M overall, because of its higher bandwidth. (explain)

GeForce GTX 280		141696 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 127296 (884%)

Texel Rate

The GeForce GTX 280 is quite a bit (about 716%) better at AF than the GeForce 810M. (explain)

GeForce GTX 280		48160 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 42256 (716%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce GTX 280 is superior to the GeForce 810M, and very much so. (explain)

GeForce GTX 280		19264 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 16312 (553%)

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 largest amount of information (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This is worked out by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to 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 ability to get to the max fill rate.
