GeForce 810M vs GeForce GT 430

Intro

Compare that to the GeForce GT 430, which makes use of a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 RAM works at a frequency of 900 MHz on this particular card. It features 96 SPUs as well as 16 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GT 430		60 Watts
	Difference: 45 Watts (300%)

Memory Bandwidth

The GeForce GT 430, in theory, should perform much faster than the GeForce 810M overall. (explain)

GeForce GT 430		28800 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 14400 (100%)

Texel Rate

The GeForce GT 430 will be quite a bit (about 90%) more effective at AF than the GeForce 810M. (explain)

GeForce GT 430		11200 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 5296 (90%)

Pixel Rate

The GeForce 810M is just a bit (more or less 5%) better at full screen anti-aliasing than the GeForce GT 430, and also will be able to handle higher resolutions while still performing well. (explain)

GeForce 810M		2952 Mpixels/sec
GeForce GT 430		2800 Mpixels/sec
	Difference: 152 (5%)

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 megabytes per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
