GeForce GTX 1050 vs Radeon HD 5970

Intro

Compare those specifications to the Radeon HD 5970, which comes with core clock speeds of 725 MHz on the GPU, and 1000 MHz on the 1024 MB of GDDR5 RAM. It features 1600 SPUs along with 160 Texture Address Units and 64 ROPs.

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

Memory Bandwidth

In theory, the Radeon HD 5970 is 123% quicker than the GeForce GTX 1050 in general, because of its greater bandwidth. (explain)

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

Texel Rate

The Radeon HD 5970 is a lot (more or less 328%) more effective at AF 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 a high resolution is important to you, then the Radeon HD 5970 is a better choice, 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 max amount of data (in units of MB per second) that can be transferred across the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses 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, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number 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 applied in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
