Radeon RX 5500 vs Radeon RX 5500 XT

Intro

Compare that to the Radeon RX 5500 XT, which features clock speeds of 1717 MHz on the GPU, and 14000 MHz on the 8192 MB of GDDR6 RAM. It features 1408 SPUs as well as 88 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT		130 Watts
Radeon RX 5500		150 Watts
	Difference: 20 Watts (15%)

Memory Bandwidth

Both cards have the exact same memory bandwidth, so theoretically they should perform exactly the same. (explain)

Texel Rate

The Radeon RX 5500 XT will be just a bit (more or less 3%) better at anisotropic filtering than the Radeon RX 5500. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 4136 (3%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5500 XT is the winner, not by a very large margin though. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
Radeon RX 5500		53440 Mpixels/sec
	Difference: 1504 (3%)

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 (counted in MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher 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 texture map elements (texels) that can be processed per second. This is worked out by multiplying the total amount of texture units by the core clock 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the number of Render Output Units by the clock 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
