GeForce 830M vs GeForce GT 210

Intro

Compare that to the GeForce GT 210, which makes use of a 40 nm design. nVidia has set the core speed at 589 MHz. The DDR3 RAM is set to run at a frequency of 800 MHz on this card. It features 16 SPUs as well as 8 TAUs and 4 Rasterization Operator 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

The GeForce 830M should in theory perform just a bit faster than the GeForce GT 210 overall. (explain)

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

Texel Rate

The GeForce 830M is a lot (about 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 a better choice, 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: Bandwidth is the largest amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. If it uses DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 are applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
