GeForce GTX 1050 3GB vs Radeon HD 5970

Intro

Compare all of that to the Radeon HD 5970, which features GPU clock speed of 725 MHz, and 1024 MB of GDDR5 memory set to run at 1000 MHz through a 256-bit bus. It also features 1600 SPUs, 160 TAUs, and 64 ROPs.

GeForce GTX 1050 3GB		86016 MB/sec
	Difference: 169984 (198%)

Texel Rate

The Radeon HD 5970 will be quite a bit (approximately 247%) better at anisotropic filtering than the GeForce GTX 1050 3GB. (explain)

Radeon HD 5970		232000 Mtexels/sec
GeForce GTX 1050 3GB		66816 Mtexels/sec
	Difference: 165184 (247%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon HD 5970 is superior to the GeForce GTX 1050 3GB, and very much so. (explain)

Radeon HD 5970		92800 Mpixels/sec
GeForce GTX 1050 3GB		33408 Mpixels/sec
	Difference: 59392 (178%)

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 (counted in MB per second) that can be moved past the external memory interface within a second. It's calculated by multiplying the bus width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, 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 are applied per 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 higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
