GeForce 810M vs GeForce GT 310

Intro

Compare those specifications to the GeForce GT 310, which makes use of a 40 nm design. nVidia has set the core speed at 589 MHz. The DDR2 memory runs at a frequency of 1000 MHz on this particular card. It features 16 SPUs along with 8 TAUs and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce GT 310 should be 11% faster than the GeForce 810M overall, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce 810M will be quite a bit (about 25%) better 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

If using a high resolution is important to you, then the GeForce 810M is superior to the GeForce GT 310, by far. (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: Bandwidth is the maximum amount of information (measured in MB per second) that can be transferred past the external memory interface in a second. The number is worked out by multiplying the bus width by the speed of its memory. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the 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 texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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