GeForce GTX 550 Ti vs Radeon RX 590

Intro

Compare that to the Radeon RX 590, which has a clock speed of 1469 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 256-bit bus, and uses a 12 nm design. It is made up of 2304 SPUs, 144 TAUs, 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, because of its higher 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 (approximately 635%) better at texture filtering 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 using high levels of AA is important to you, then the Radeon RX 590 is the winner, and very much so. (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 information (measured in MB per second) that can be transported over the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the video 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 maximum amount of pixels the video card can possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
