GeForce RTX 2070 Super vs Radeon RX 550

Intro

Compare all of that to the Radeon RX 550, which uses a 14 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 RAM runs at a speed of 1750 MHz on this card. It features 512 SPUs along with 32 Texture Address Units and 16 Rasterization Operator Units.

Radeon RX 550		35200 Mtexels/sec
	Difference: 221600 (630%)

Pixel Rate

If running with a high resolution is important to you, then the GeForce RTX 2070 Super is the winner, and very much so. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon RX 550		17600 Mpixels/sec
	Difference: 85120 (484%)

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: Memory bandwidth is the max amount of data (in units of megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, 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 maximum amount of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on 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 memory bandwidth is, the lower the potential to get to the maximum fill rate.
