Radeon RX 5500 vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which comes with core clock speeds of 1717 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1408 SPUs as well as 88 Texture Address Units and 32 ROPs.

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 exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The Radeon RX 5500 XT is just a bit (more or less 3%) more effective 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, though only just barely. (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 maximum amount of data (counted in MB per second) that can be moved across the external memory interface in one second. It is worked out by multiplying the interface width by its memory speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines 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 also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
