GeForce RTX 2080 vs Radeon RX 5700

Intro

Compare all of that to the Radeon RX 5700, which has a core clock speed of 1465 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 256-bit bus, and uses a 7 nm design. It is made up of 2304 SPUs, 144 Texture Address Units, and 64 Raster Operation 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 the exact same bandwidth, so in theory they should perform exactly the same. (explain)

Texel Rate

The GeForce RTX 2080 will be quite a bit (about 32%) faster with regards to texture filtering than the Radeon RX 5700. (explain)

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

Pixel Rate

The GeForce RTX 2080 should be a small bit (approximately 3%) better at full screen anti-aliasing than the Radeon RX 5700, and should be able to handle higher resolutions better. (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 maximum amount of data (in units of MB per second) that can be transported over the external memory interface in a second. The number is worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at handling 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 card could possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on 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 max fill rate.
