GeForce GTX 550 Ti vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which comes with core clock speeds of 1469 MHz on the GPU, and 2000 MHz on the 8192 MB of GDDR5 memory. It features 2304 SPUs as well as 144 Texture Address Units and 32 ROPs.

GeForce GTX 550 Ti		116 Watts
Radeon RX 590		175 Watts
	Difference: 59 Watts (51%)

Memory Bandwidth

In theory, the Radeon RX 590 will be 166% quicker than the GeForce GTX 550 Ti in general, because of its greater data rate. (explain)

Radeon RX 590		262144 MB/sec
GeForce GTX 550 Ti		98496 MB/sec
	Difference: 163648 (166%)

Texel Rate

The Radeon RX 590 should be a lot (more or less 635%) better at AF than the GeForce GTX 550 Ti. (explain)

Radeon RX 590		211536 Mtexels/sec
GeForce GTX 550 Ti		28800 Mtexels/sec
	Difference: 182736 (635%)

Pixel Rate

The Radeon RX 590 should be a lot (about 118%) faster with regards to AA than the GeForce GTX 550 Ti, and also will be capable of handling higher resolutions better. (explain)

Radeon RX 590		47008 Mpixels/sec
GeForce GTX 550 Ti		21600 Mpixels/sec
	Difference: 25408 (118%)

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 maximum amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
