Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 1050		75 Watts
Radeon HD 5970		294 Watts
	Difference: 219 Watts (292%)

Memory Bandwidth

In theory, the Radeon HD 5970 will be 123% faster than the GeForce GTX 1050 in general, due to its higher data rate. (explain)

Radeon HD 5970		256000 MB/sec
GeForce GTX 1050		114688 MB/sec
	Difference: 141312 (123%)

Texel Rate

The Radeon HD 5970 is quite a bit (about 328%) faster with regards to texture filtering than the GeForce GTX 1050. (explain)

Radeon HD 5970		232000 Mtexels/sec
GeForce GTX 1050		54160 Mtexels/sec
	Difference: 177840 (328%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5970 is superior to the GeForce GTX 1050, by a large margin. (explain)

Radeon HD 5970		92800 Mpixels/sec
GeForce GTX 1050		43328 Mpixels/sec
	Difference: 49472 (114%)

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.

One or more cards in this comparison are multi-core. This means that their bandwidth, texel and pixel rates are theoretically doubled - this does not mean the card will actually perform twice as fast, but only that it should in theory be able to. Actual game benchmarks will give a more accurate idea of what it's capable of.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This number is worked out 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 video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the the core speed of the card. 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 output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
