GeForce RTX 2080 vs Radeon RX 5700

Intro

Compare those specifications to the Radeon RX 5700, which features clock speeds of 1465 MHz on the GPU, and 1750 MHz on the 8096 MB of GDDR6 RAM. It features 2304 SPUs along with 144 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
GeForce RTX 2080		215 Watts
	Difference: 35 Watts (19%)

Memory Bandwidth

Both cards have exactly the same memory bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce RTX 2080 should be a lot (approximately 32%) more effective at anisotropic filtering than the Radeon RX 5700. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 67800 (32%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the GeForce RTX 2080 is the winner, but only just. (explain)

GeForce RTX 2080		96960 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 3200 (3%)

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 information (in units of megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to the local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
