GeForce RTX 2070 vs Radeon RX Vega 56

Intro

The GeForce RTX 2070 comes with a GPU core speed of 1410 MHz, and the 8192 MB of GDDR6 RAM runs at 14 MHz through a 256-bit bus. It also features 2304 SPUs, 144 TAUs, and 64 Raster Operation Units.

Compare all that to the Radeon RX Vega 56, which comes with a clock frequency of 1156 MHz and a HBM2 memory frequency of 1600 MHz. It also makes use of a 2048-bit memory bus, and makes use of a 14 nm design. It is made up of 3584 SPUs, 224 Texture Address Units, and 64 Raster Operation Units.

GeForce RTX 2070 175 Watts
Radeon RX Vega 56 210 Watts
Difference: 35 Watts (20%)

Memory Bandwidth

Theoretically, the GeForce RTX 2070 should be a small bit faster than the Radeon RX Vega 56 in general. (explain)

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

Texel Rate

The Radeon RX Vega 56 should be a lot (about 28%) better at anisotropic filtering than the GeForce RTX 2070. (explain)

Radeon RX Vega 56 258944 Mtexels/sec
GeForce RTX 2070 203040 Mtexels/sec
Difference: 55904 (28%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2070 is superior to the Radeon RX Vega 56, and very much so. (explain)

GeForce RTX 2070 90240 Mpixels/sec
Radeon RX Vega 56 73984 Mpixels/sec
Difference: 16256 (22%)

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.

Memory Bandwidth: Memory bandwidth is the largest amount of data (counted in MB per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, 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 texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total number 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

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