Radeon RX 480 vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which comes with a core clock frequency of 1670 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and uses a 7 nm design. It features 1408 SPUs, 88 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 480 should in theory perform just a bit faster than the Radeon RX 5500 overall. (explain)

Radeon RX 480		262144 MB/sec
Radeon RX 5500		229376 MB/sec
	Difference: 32768 (14%)

Texel Rate

The Radeon RX 480 should be a bit (about 10%) faster with regards to AF than the Radeon RX 5500. (explain)

Radeon RX 480		161280 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 14320 (10%)

Pixel Rate

The Radeon RX 5500 should be a lot (about 49%) more effective at AA than the Radeon RX 480, and also will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 480		35840 Mpixels/sec
	Difference: 17600 (49%)

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 information (counted in MB per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high 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 higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
