GeForce RTX 2080 SUPER vs Radeon RX Vega 56

Intro

Compare those specifications to the Radeon RX Vega 56, which uses a 14 nm design. AMD has set the core speed at 1156 MHz. The HBM2 memory runs at a frequency of 1600 MHz on this particular card. It features 3584 SPUs along with 224 TAUs and 64 ROPs.

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

The GeForce RTX 2080 SUPER should in theory perform quite a bit 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 should be a lot (approximately 22%) better at 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 resolution is important to you, then the GeForce RTX 2080 SUPER is the winner, by a large margin. (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: Memory bandwidth is the largest amount of data (counted in megabytes per second) that can be transported past the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR memory, it must 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, High Dynamic Range 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 worked out by multiplying the total texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Render Output Units 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 rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
