Radeon RX 5500 vs Radeon RX 5500 XT

Intro

Compare all that to the Radeon RX 5500 XT, which comes with GPU clock speed of 1717 MHz, and 8192 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also features 1408 SPUs, 88 TAUs, and 32 Raster Operation 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 exactly the same bandwidth, so in theory they should have identical performance. (explain)

Texel Rate

The Radeon RX 5500 XT should be a little bit (more or less 3%) more effective at AF 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 using a high screen resolution is important to you, then the Radeon RX 5500 XT is a better choice, 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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved across the external memory interface within a second. It is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 that the graphics chip can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
