GeForce 810M vs GeForce GT 310

Intro

Compare all that to the GeForce GT 310, which uses a 40 nm design. nVidia has clocked the core speed at 589 MHz. The DDR2 memory runs at a frequency of 1000 MHz on this card. It features 16 SPUs as well as 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

The GeForce GT 310 should in theory perform a small bit faster than the GeForce 810M in general. (explain)

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

Texel Rate

The GeForce 810M should be quite a bit (about 25%) faster with regards to 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 a lot (about 25%) more effective at FSAA than the GeForce GT 310, and will be able to handle higher resolutions better. (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 (in units of MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is worked out by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at 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 the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated 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 filling the screen with pixels (the image). The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
