Compare any two graphics cards:
VS

Radeon RX 480 4GB vs Radeon RX 5500 XT

Intro

The Radeon RX 480 4GB features a GPU clock speed of 1120 MHz, and the 4096 MB of GDDR5 memory is set to run at 1750 MHz through a 256-bit bus. It also features 2304 Stream Processors, 144 TAUs, and 32 Raster Operation Units.

Compare those specifications to the Radeon RX 5500 XT, which uses a 7 nm design. AMD has set the core frequency at 1717 MHz. The GDDR6 memory runs at a speed of 1750 MHz on this particular card. It features 1408 SPUs along with 88 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5500 XT 130 Watts
Radeon RX 480 4GB 150 Watts
Difference: 20 Watts (15%)

Memory Bandwidth

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

Texel Rate

The Radeon RX 480 4GB should be just a bit (approximately 7%) more effective at texture filtering than the Radeon RX 5500 XT. (explain)

Radeon RX 480 4GB 161280 Mtexels/sec
Radeon RX 5500 XT 151096 Mtexels/sec
Difference: 10184 (7%)

Pixel Rate

The Radeon RX 5500 XT will be a lot (more or less 53%) faster with regards to AA than the Radeon RX 480 4GB, and capable of handling higher resolutions more effectively. (explain)

Radeon RX 5500 XT 54944 Mpixels/sec
Radeon RX 480 4GB 35840 Mpixels/sec
Difference: 19104 (53%)

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.

Memory Bandwidth: Memory bandwidth is the max amount of information (in units of MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This is calculated 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 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 most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
