GeForce 9800 GX2 vs GeForce GT 210

Intro

Compare that to the GeForce GT 210, which has core 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 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce 9800 GX2		197 Watts
	Difference: 166 Watts (535%)

Memory Bandwidth

The GeForce 9800 GX2 should in theory be quite a bit faster than the GeForce GT 210 overall. (explain)

GeForce 9800 GX2		128000 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 115200 (900%)

Texel Rate

The GeForce 9800 GX2 is much (about 1530%) faster with regards to AF than the GeForce GT 210. (explain)

GeForce 9800 GX2		76800 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 72088 (1530%)

Pixel Rate

The GeForce 9800 GX2 should be much (more or less 715%) faster with regards to anti-aliasing than the GeForce GT 210, and should be capable of handling higher screen resolutions more effectively. (explain)

GeForce 9800 GX2		19200 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 16844 (715%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Memory bandwidth is the maximum amount of data (counted in MB per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per 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 graphics 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 the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
