Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GT 210		31 Watts
Radeon R7 250		65 Watts
	Difference: 34 Watts (110%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 250 should be 475% quicker than the GeForce GT 210 overall, because of its greater bandwidth. (explain)

Radeon R7 250		73600 MB/sec
GeForce GT 210		12800 MB/sec
	Difference: 60800 (475%)

Texel Rate

The Radeon R7 250 should be a lot (more or less 409%) faster with regards to texture filtering than the GeForce GT 210. (explain)

Radeon R7 250		24000 Mtexels/sec
GeForce GT 210		4712 Mtexels/sec
	Difference: 19288 (409%)

Pixel Rate

The Radeon R7 250 should be a lot (approximately 240%) better at anti-aliasing than the GeForce GT 210, and should be able to handle higher screen resolutions while still performing well. (explain)

Radeon R7 250		8000 Mpixels/sec
GeForce GT 210		2356 Mpixels/sec
	Difference: 5644 (240%)

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 largest amount of data (in units of megabytes per second) that can be transferred over the external memory interface in a second. The number is worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, 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 number of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
