GeForce RTX 2070 Super vs Radeon RX 5700

Intro

Compare those specifications to the Radeon RX 5700, which comes with GPU clock speed of 1465 MHz, and 8096 MB of GDDR6 RAM running at 1750 MHz through a 256-bit bus. It also features 2304 SPUs, 144 Texture Address Units, and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5700		180 Watts
GeForce RTX 2070 Super		215 Watts
	Difference: 35 Watts (19%)

Memory Bandwidth

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

Texel Rate

The GeForce RTX 2070 Super will be much (more or less 22%) better at anisotropic filtering than the Radeon RX 5700. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
Radeon RX 5700		210960 Mtexels/sec
	Difference: 45840 (22%)

Pixel Rate

If using a high resolution is important to you, then the GeForce RTX 2070 Super is superior to the Radeon RX 5700, though only just barely. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon RX 5700		93760 Mpixels/sec
	Difference: 8960 (10%)

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.

Price Comparison

Specifications

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied 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. Pixel rate is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
