GeForce GTX 550 Ti vs Radeon RX 590

Intro

Compare those specs to the Radeon RX 590, which comes with GPU clock speed of 1469 MHz, and 8192 MB of GDDR5 RAM set to run at 2000 MHz through a 256-bit bus. It also is made up of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

Theoretically speaking, the Radeon RX 590 is 166% faster than the GeForce GTX 550 Ti overall, due to its greater bandwidth. (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 quite a bit (more or less 635%) faster with regards to 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

If running with high levels of AA is important to you, then the Radeon RX 590 is a better choice, by far. (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 max amount of data (measured in megabytes per second) that can be transported over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated 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 drawing the pixels (image) on the screen. The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
