GeForce GTX 550 Ti vs Radeon RX 470 4GB

Intro

Compare those specifications to the Radeon RX 470 4GB, which comes with GPU core speed of 926 MHz, and 4096 MB of GDDR5 memory set to run at 1650 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

GeForce GTX 550 Ti		116 Watts
Radeon RX 470 4GB		120 Watts
	Difference: 4 Watts (3%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 470 4GB will be 114% faster than the GeForce GTX 550 Ti in general, due to its higher bandwidth. (explain)

Radeon RX 470 4GB		211200 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 112704 (114%)

Texel Rate

The Radeon RX 470 4GB should be quite a bit (approximately 312%) better at anisotropic filtering than the GeForce GTX 550 Ti. (explain)

Radeon RX 470 4GB		118528 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 89728 (312%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 470 4GB is superior to the GeForce GTX 550 Ti, by far. (explain)

Radeon RX 470 4GB		29632 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 8032 (37%)

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 data (in units of megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This number is calculated 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 in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock 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 also depends on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
