Radeon RX 5500 vs Radeon RX 590

Intro

Compare all that to the Radeon RX 590, which has a GPU core clock speed of 1469 MHz, and 8192 MB of GDDR5 memory set to run at 2000 MHz through a 256-bit bus. It also is comprised of 2304 Stream Processors, 144 Texture Address Units, and 32 ROPs.

The Radeon RX 590 will be quite a bit (approximately 44%) faster with regards to texture filtering 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 should be a bit (about 14%) more effective at anti-aliasing than the Radeon RX 590, and also should be able to handle higher resolutions more effectively. (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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The higher the texel rate, the better the video 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 maximum number of pixels that the graphics chip can possibly record to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
