GeForce RTX 2080 SUPER vs Radeon RX Vega 56

Intro

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

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

Memory Bandwidth

In theory, the GeForce RTX 2080 SUPER should perform much faster than the Radeon RX Vega 56 in general. (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 quite a bit (approximately 22%) faster with regards to texture filtering 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 a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is a better choice, 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 data (counted in MB per second) that can be transferred over the external memory interface in one second. It's calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also called 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 - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
