GeForce 830M vs GeForce GT 210

Intro

Compare those specs to the GeForce GT 210, which has a GPU core clock speed of 589 MHz, and 512 MB of DDR3 memory running at 800 MHz through a 64-bit bus. It also is comprised of 16 SPUs, 8 Texture Address Units, and 4 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the GeForce 830M should be 13% faster than the GeForce GT 210 overall, due to its greater data rate. (explain)

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

Texel Rate

The GeForce 830M is a lot (more or less 249%) more effective 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 running with high levels of AA is important to you, then the GeForce 830M is the winner, 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 maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, 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 is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the video 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 card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
