Radeon RX 5600 vs Radeon RX Vega 56

Intro

Compare those specifications to the Radeon RX Vega 56, which has a GPU core clock speed of 1156 MHz, and 8192 MB of HBM2 RAM set to run at 1600 MHz through a 2048-bit bus. It also features 3584 SPUs, 224 TAUs, and 64 ROPs.

Radeon RX 5600		294912 MB/sec
	Difference: 124518 (42%)

Texel Rate

The Radeon RX Vega 56 will be quite a bit (more or less 47%) better at anisotropic filtering than the Radeon RX 5600. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon RX 5600		176000 Mtexels/sec
	Difference: 82944 (47%)

Pixel Rate

The Radeon RX 5600 is just a bit (about 19%) faster with regards to FSAA than the Radeon RX Vega 56, and also will be capable of handling higher screen resolutions more effectively. (explain)

Radeon RX 5600		88000 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 14016 (19%)

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 transferred over the external memory interface within a second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This number is worked out by multiplying the total number of texture units by the core clock 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 maximum number 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 amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
