GeForce 9800 GX2 vs GeForce GT 210

Intro

Compare that to the GeForce GT 210, which comes with clock speeds of 589 MHz on the GPU, and 800 MHz on the 512 MB of DDR3 memory. It features 16 SPUs as well as 8 TAUs and 4 Rasterization Operator Units.

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

Performance-wise, the GeForce 9800 GX2 should in theory be quite a bit superior to the GeForce GT 210 in general. (explain)

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

Texel Rate

The GeForce 9800 GX2 will be much (more or less 1530%) faster with regards to anisotropic filtering than the GeForce GT 210. (explain)

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

Pixel Rate

If running with a high resolution is important to you, then the GeForce 9800 GX2 is a better choice, and very much so. (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 max amount of information (measured in MB per second) that can be moved across the external memory interface in a second. The number 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 higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

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