Radeon HD 7790 vs Radeon RX 5600

Intro

Compare all that to the Radeon RX 5600, which has GPU core speed of 1375 MHz, and 6144 MB of GDDR6 memory set to run at 1500 MHz through a 192-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

Radeon HD 7790		96000 MB/sec
	Difference: 198912 (207%)

Texel Rate

The Radeon RX 5600 is quite a bit (more or less 214%) faster with regards to AF than the Radeon HD 7790. (explain)

Radeon RX 5600		176000 Mtexels/sec
Radeon HD 7790		56000 Mtexels/sec
	Difference: 120000 (214%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5600 is the winner, by a large margin. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon HD 7790		16000 Mpixels/sec
	Difference: 72000 (450%)

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 (measured in megabytes per second) that can be transferred over the external memory interface in a second. It's worked out by multiplying the card's bus width by its memory speed. If it uses DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

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