GeForce 830M vs GeForce GT 210

Intro

Compare those specifications to the GeForce GT 210, which has core clock speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 RAM. It features 16 SPUs along with 8 Texture Address Units and 4 Rasterization Operator Units.

GeForce 830M		25 Watts
GeForce GT 210		31 Watts
	Difference: 6 Watts (24%)

Memory Bandwidth

As far as performance goes, the GeForce 830M should in theory be a bit superior to the GeForce GT 210 in general. (explain)

GeForce 830M		14400 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 1600 (13%)

Texel Rate

The GeForce 830M will be quite a bit (about 249%) better at anisotropic filtering than the GeForce GT 210. (explain)

GeForce 830M		16464 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 11752 (249%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce 830M is superior to the GeForce GT 210, by far. (explain)

GeForce 830M		8232 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 5876 (249%)

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 largest amount of information (in units of megabytes per second) that can be transferred over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
