GeForce RTX 2080 SUPER vs Radeon RX Vega 56

Intro

Compare those specs to the Radeon RX Vega 56, which makes use of a 14 nm design. AMD has set the core frequency at 1156 MHz. The HBM2 RAM is set to run at a frequency of 1600 MHz on this specific model. It features 3584 SPUs along with 224 TAUs and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX Vega 56		210 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 40 Watts (19%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER should be 21% faster than the Radeon RX Vega 56 in general, because of its higher data rate. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX Vega 56		419430 MB/sec
	Difference: 88474 (21%)

Texel Rate

The GeForce RTX 2080 SUPER will be a lot (about 22%) faster with regards to AF than the Radeon RX Vega 56. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX Vega 56		258944 Mtexels/sec
	Difference: 57856 (22%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is the winner, and very much so. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 31616 (43%)

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 information (in units of megabytes per second) that can be transported past the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
