GeForce 810M vs GeForce GT 340 1GB

Intro

Compare that to the GeForce GT 340 1GB, which makes use of a 40 nm design. nVidia has set the core speed at 550 MHz. The GDDR5 RAM runs at a frequency of 850 MHz on this specific card. It features 96 SPUs as well as 32 Texture Address Units and 8 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GT 340 1GB		69 Watts
	Difference: 54 Watts (360%)

Memory Bandwidth

Theoretically speaking, the GeForce GT 340 1GB is 278% quicker than the GeForce 810M overall, because of its greater bandwidth. (explain)

GeForce GT 340 1GB		54400 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 40000 (278%)

Texel Rate

The GeForce GT 340 1GB should be quite a bit (about 198%) better at AF than the GeForce 810M. (explain)

GeForce GT 340 1GB		17600 Mtexels/sec
GeForce 810M		5904 Mtexels/sec
	Difference: 11696 (198%)

Pixel Rate

The GeForce GT 340 1GB should be much (more or less 49%) faster with regards to full screen anti-aliasing than the GeForce 810M, and will be able to handle higher screen resolutions while still performing well. (explain)

GeForce GT 340 1GB		4400 Mpixels/sec
GeForce 810M		2952 Mpixels/sec
	Difference: 1448 (49%)

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 transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. 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 potential to reach the max fill rate.
