GeForce 810M vs GeForce 9800 GTX

Intro

Compare that to the GeForce 9800 GTX, which uses a 65 nm design. nVidia has set the core speed at 675 MHz. The GDDR3 RAM works at a frequency of 1100 MHz on this particular card. It features 128 SPUs as well as 64 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce 9800 GTX		140 Watts
	Difference: 125 Watts (833%)

Memory Bandwidth

As far as performance goes, the GeForce 9800 GTX should in theory be a lot better than the GeForce 810M in general. (explain)

GeForce 9800 GTX		70400 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 56000 (389%)

Texel Rate

The GeForce 9800 GTX is quite a bit (approximately 632%) more effective at texture filtering than the GeForce 810M. (explain)

GeForce 9800 GTX		43200 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 37296 (632%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce 9800 GTX is the winner, by far. (explain)

GeForce 9800 GTX		10800 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 7848 (266%)

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 maximum amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 per second. This is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the video 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 Raster Operations Pipelines by the clock 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 fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
