GeForce RTX 2080 vs Radeon RX 5700

Intro

Compare all that to the Radeon RX 5700, which comes with GPU clock speed of 1465 MHz, and 8096 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also is made up of 2304 Stream Processors, 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 exactly the same bandwidth, so theoretically they should perform the same. (explain)

Texel Rate

The GeForce RTX 2080 is a lot (approximately 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 bit (more or less 3%) faster with regards to FSAA than the Radeon RX 5700, and also capable of handling higher resolutions while still performing well. (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 moved over the external memory interface in one second. It is worked out by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
