Radeon RX 480 4GB vs Radeon RX 5500

Intro

Compare all of that to the Radeon RX 5500, which uses a 7 nm design. AMD has set the core speed at 1670 MHz. The GDDR6 memory is set to run at a frequency of 14000 MHz on this card. It features 1408 SPUs as well as 88 Texture Address Units 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 exactly the same. (explain)

Texel Rate

The Radeon RX 480 4GB is a small bit (approximately 10%) better at texture filtering than the Radeon RX 5500. (explain)

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

Pixel Rate

The Radeon RX 5500 will be a lot (more or less 49%) more effective at FSAA than the Radeon RX 480 4GB, and should be capable of handling higher resolutions while still performing well. (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: Bandwidth is the max amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 number of texture map elements (texels) that are processed per second. This is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
