Radeon RX 480 4GB vs Radeon RX 5500

Intro

Compare those specifications to the Radeon RX 5500, which features core clock speeds of 1670 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR6 RAM. It features 1408 SPUs along with 88 TAUs and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

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

Texel Rate

The Radeon RX 480 4GB is a little bit (about 10%) more effective at AF than the Radeon RX 5500. (explain)

Radeon RX 480 4GB		161280 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 14320 (10%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 5500 is a better choice, and very much so. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 480 4GB		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 maximum amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the interface width by its memory speed. In the case of DDR memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units of the card by the core 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
