Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon R7 370 4G		110 Watts
GeForce GTX 280		236 Watts
	Difference: 126 Watts (115%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 370 4G will be 26% quicker than the GeForce GTX 280 overall, because of its higher bandwidth. (explain)

Radeon R7 370 4G		179200 MB/sec
GeForce GTX 280		141696 MB/sec
	Difference: 37504 (26%)

Texel Rate

The Radeon R7 370 4G is quite a bit (more or less 30%) better at texture filtering than the GeForce GTX 280. (explain)

Radeon R7 370 4G		62400 Mtexels/sec
GeForce GTX 280		48160 Mtexels/sec
	Difference: 14240 (30%)

Pixel Rate

The Radeon R7 370 4G should be much (more or less 62%) faster with regards to full screen anti-aliasing than the GeForce GTX 280, and also should be able to handle higher screen resolutions without slowing down too much. (explain)

Radeon R7 370 4G		31200 Mpixels/sec
GeForce GTX 280		19264 Mpixels/sec
	Difference: 11936 (62%)

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 largest amount of information (counted in megabytes per second) that can be moved past the external memory interface in a second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one 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 video card will be at 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 that the graphics chip could possibly record to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
