GeForce GT 210 vs Radeon HD 7850

Intro

Compare that to the Radeon HD 7850, which has core speeds of 860 MHz on the GPU, and 1200 MHz on the 2048 MB of GDDR5 memory. It features 1024 SPUs as well as 64 Texture Address Units and 32 ROPs.

GeForce GT 210		31 Watts
Radeon HD 7850		130 Watts
	Difference: 99 Watts (319%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 7850 is 1100% quicker than the GeForce GT 210 in general, because of its higher bandwidth. (explain)

Radeon HD 7850		153600 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 140800 (1100%)

Texel Rate

The Radeon HD 7850 will be quite a bit (more or less 1068%) more effective at texture filtering than the GeForce GT 210. (explain)

Radeon HD 7850		55040 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 50328 (1068%)

Pixel Rate

The Radeon HD 7850 will be a lot (approximately 1068%) more effective at AA than the GeForce GT 210, and able to handle higher screen resolutions more effectively. (explain)

Radeon HD 7850		27520 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 25164 (1068%)

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 moved over the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the graphics 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 could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
