Radeon R7 360		100 Watts
Radeon HD 5830		175 Watts
	Difference: 75 Watts (75%)

Memory Bandwidth

Theoretically speaking, the Radeon HD 5830 should perform quite a bit faster than the Radeon R7 360 in general. (explain)

Radeon HD 5830		128000 MB/sec
Radeon R7 360		104000 MB/sec
	Difference: 24000 (23%)

Texel Rate

The Radeon R7 360 will be just a bit (more or less 13%) better at texture filtering than the Radeon HD 5830. (explain)

Radeon R7 360		50400 Mtexels/sec
Radeon HD 5830		44800 Mtexels/sec
	Difference: 5600 (13%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 360 is superior to the Radeon HD 5830, by a large margin. (explain)

Radeon R7 360		16800 Mpixels/sec
Radeon HD 5830		12800 Mpixels/sec
	Difference: 4000 (31%)

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 across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If 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 amount of texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
