Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon R7 360 will be 2% quicker than the Radeon HD 4790 overall, because of its higher bandwidth. (explain)

Radeon R7 360		104000 MB/sec
Radeon HD 4790		102400 MB/sec
	Difference: 1600 (2%)

Texel Rate

The Radeon R7 360 will be a lot (more or less 163%) faster with regards to AF than the Radeon HD 4790. (explain)

Radeon R7 360		50400 Mtexels/sec
Radeon HD 4790		19200 Mtexels/sec
	Difference: 31200 (163%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon R7 360 is the winner, and very much so. (explain)

Radeon R7 360		16800 Mpixels/sec
Radeon HD 4790		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 information (in units of MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
