Radeon RX 5500 vs Radeon RX 590

Intro

Compare those specifications to the Radeon RX 590, which uses a 12 nm design. AMD has clocked the core speed at 1469 MHz. The GDDR5 memory runs at a frequency of 2000 MHz on this specific card. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

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

Texel Rate

The Radeon RX 590 should be much (more or less 44%) better at AF than the Radeon RX 5500. (explain)

Radeon RX 590		211536 Mtexels/sec
Radeon RX 5500		146960 Mtexels/sec
	Difference: 64576 (44%)

Pixel Rate

The Radeon RX 5500 will be a small bit (about 14%) more effective at AA than the Radeon RX 590, and also should be capable of handling higher resolutions without slowing down too much. (explain)

Radeon RX 5500		53440 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 6432 (14%)

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 max amount of data (counted in MB per second) that can be moved past the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
