GeForce RTX 2060 vs Radeon RX Vega 56

Intro

Compare those specs to the Radeon RX Vega 56, which comes with clock speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 memory. It features 3584 SPUs along with 224 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2060		160 Watts
Radeon RX Vega 56		210 Watts
	Difference: 50 Watts (31%)

Memory Bandwidth

In theory, the Radeon RX Vega 56 is 22% faster than the GeForce RTX 2060 in general, because of its greater data rate. (explain)

Radeon RX Vega 56		419430 MB/sec
GeForce RTX 2060		344064 MB/sec
	Difference: 75366 (22%)

Texel Rate

The Radeon RX Vega 56 is quite a bit (more or less 58%) more effective at AF than the GeForce RTX 2060. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
GeForce RTX 2060		163800 Mtexels/sec
	Difference: 95144 (58%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX Vega 56 is a better choice, but it probably won't make a huge difference. (explain)

Radeon RX Vega 56		73984 Mpixels/sec
GeForce RTX 2060		65520 Mpixels/sec
	Difference: 8464 (13%)

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 past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the video 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 that 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 amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
