GeForce GT 210 vs GeForce GT 430 1GB

Intro

Compare those specs to the GeForce GT 430 1GB, which uses a 40 nm design. nVidia has set the core frequency at 700 MHz. The GDDR3 memory runs at a frequency of 900 MHz on this particular card. It features 96 SPUs along with 16 Texture Address Units and 4 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
GeForce GT 430 1GB		60 Watts
	Difference: 29 Watts (94%)

Memory Bandwidth

The GeForce GT 430 1GB should theoretically perform much faster than the GeForce GT 210 overall. (explain)

GeForce GT 430 1GB		28800 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 16000 (125%)

Texel Rate

The GeForce GT 430 1GB should be quite a bit (more or less 138%) more effective at anisotropic filtering than the GeForce GT 210. (explain)

GeForce GT 430 1GB		11200 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 6488 (138%)

Pixel Rate

The GeForce GT 430 1GB should be just a bit (about 19%) faster with regards to FSAA than the GeForce GT 210, and should be able to handle higher resolutions without losing too much performance. (explain)

GeForce GT 430 1GB		2800 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 444 (19%)

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 max amount of data (in units of megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the bus width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum number of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the the core speed of the card. 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 rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
