GeForce GT 210 vs Radeon HD 7950

Intro

Compare all of that to the Radeon HD 7950, which has core clock speeds of 800 MHz on the GPU, and 1250 MHz on the 1536 MB of GDDR5 memory. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.

GeForce GT 210		12800 MB/sec
	Difference: 227200 (1775%)

Texel Rate

The Radeon HD 7950 should be much (about 1802%) more effective at AF than the GeForce GT 210. (explain)

Radeon HD 7950		89600 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 84888 (1802%)

Pixel Rate

The Radeon HD 7950 will be quite a bit (approximately 987%) better at full screen anti-aliasing than the GeForce GT 210, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon HD 7950		25600 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 23244 (987%)

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: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be transferred past the external memory interface in a second. It's worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one 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 the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
