GeForce 830M vs GeForce GT 210

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

In theory, the GeForce 830M should be 13% faster than the GeForce GT 210 overall, because of its greater bandwidth. (explain)

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

Texel Rate

The GeForce 830M should be a lot (more or less 249%) better at AF than the GeForce GT 210. (explain)

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

Pixel Rate

If using high levels of AA is important to you, then the GeForce 830M is superior to the GeForce GT 210, by a large margin. (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: Bandwidth is the maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total 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 most pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
