GeForce 810M vs GeForce GT 310

Intro

Compare that to the GeForce GT 310, which uses a 40 nm design. nVidia has set the core frequency at 589 MHz. The DDR2 memory runs at a frequency of 1000 MHz on this model. It features 16 SPUs along with 8 TAUs and 4 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce 810M		15 Watts
GeForce GT 310		31 Watts
	Difference: 16 Watts (107%)

Memory Bandwidth

As far as performance goes, the GeForce GT 310 should in theory be just a bit better than the GeForce 810M overall. (explain)

GeForce GT 310		16000 MB/sec
GeForce 810M		14400 MB/sec
	Difference: 1600 (11%)

Texel Rate

The GeForce 810M should be much (about 25%) more effective at anisotropic filtering than the GeForce GT 310. (explain)

GeForce 810M		5904 Mtexels/sec
GeForce GT 310		4712 Mtexels/sec
	Difference: 1192 (25%)

Pixel Rate

The GeForce 810M is quite a bit (approximately 25%) faster with regards to full screen anti-aliasing than the GeForce GT 310, and able to handle higher screen resolutions without losing too much performance. (explain)

GeForce 810M		2952 Mpixels/sec
GeForce GT 310		2356 Mpixels/sec
	Difference: 596 (25%)

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 MB per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
