Radeon RX 480 vs Radeon RX 5500

Intro

Compare that to the Radeon RX 5500, which comes with a core clock speed of 1670 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit memory bus, and uses a 7 nm design. It is comprised of 1408 SPUs, 88 TAUs, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

As far as performance goes, the Radeon RX 480 should in theory be just a bit superior to the Radeon RX 5500 in general. (explain)

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

Texel Rate

The Radeon RX 480 will be a bit (about 10%) more effective at texture filtering 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%) better at AA than the Radeon RX 480, and should be able to handle higher resolutions more effectively. (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 maximum amount of data (counted in MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied in one second. This number is worked out by multiplying the total texture units by the core clock 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 processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
