Radeon R7 360		100 Watts
GeForce 8800 GT 512MB		105 Watts
	Difference: 5 Watts (5%)

Memory Bandwidth

Theoretically speaking, the Radeon R7 360 will be 81% quicker than the GeForce 8800 GT 512MB in general, because of its higher bandwidth. (explain)

Radeon R7 360		104000 MB/sec
GeForce 8800 GT 512MB		57600 MB/sec
	Difference: 46400 (81%)

Texel Rate

The Radeon R7 360 should be much (about 50%) more effective at AF than the GeForce 8800 GT 512MB. (explain)

Radeon R7 360		50400 Mtexels/sec
GeForce 8800 GT 512MB		33600 Mtexels/sec
	Difference: 16800 (50%)

Pixel Rate

The Radeon R7 360 will be a lot (more or less 75%) faster with regards to full screen anti-aliasing than the GeForce 8800 GT 512MB, and should be capable of handling higher resolutions more effectively. (explain)

Radeon R7 360		16800 Mpixels/sec
GeForce 8800 GT 512MB		9600 Mpixels/sec
	Difference: 7200 (75%)

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 max amount of data (in units of MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 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 AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. 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 lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
