Radeon RX 5500 vs Radeon RX 5500 XT

Intro

Compare those specifications to the Radeon RX 5500 XT, which comes with 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 bandwidth, so theoretically they should have identical performance. (explain)

Texel Rate

The Radeon RX 5500 XT will be a little bit (approximately 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

The Radeon RX 5500 XT should be a little bit (more or less 3%) better at anti-aliasing than the Radeon RX 5500, and will be able to handle higher resolutions without slowing down too much. (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 over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If the card has DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write 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 the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
