GeForce RTX 2070 Super vs Radeon RX Vega 56

Intro

Compare those specs to the Radeon RX Vega 56, which has core speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 RAM. It features 3584 SPUs along with 224 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX Vega 56		210 Watts
GeForce RTX 2070 Super		215 Watts
	Difference: 5 Watts (2%)

Memory Bandwidth

In theory, the GeForce RTX 2070 Super is 9% quicker than the Radeon RX Vega 56 overall, because of its greater data rate. (explain)

GeForce RTX 2070 Super		458752 MB/sec
Radeon RX Vega 56		419430 MB/sec
	Difference: 39322 (9%)

Texel Rate

The Radeon RX Vega 56 should be just a bit (more or less 1%) more effective at anisotropic filtering than the GeForce RTX 2070 Super. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 2144 (1%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2070 Super is the winner, and very much so. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 28736 (39%)

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 MB per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied per second. This is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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