GeForce RTX 2080 vs Radeon RX 590

Intro

Compare all of that to the Radeon RX 590, which comes with a clock frequency of 1469 MHz and a GDDR5 memory speed of 2000 MHz. It also features a 256-bit bus, and makes use of a 12 nm design. It features 2304 SPUs, 144 Texture Address Units, and 32 ROPs.

Radeon RX 590		175 Watts
GeForce RTX 2080		215 Watts
	Difference: 40 Watts (23%)

Memory Bandwidth

In theory, the GeForce RTX 2080 is 75% faster than the Radeon RX 590 overall, due to its greater data rate. (explain)

GeForce RTX 2080		458752 MB/sec
Radeon RX 590		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The GeForce RTX 2080 is a lot (more or less 32%) faster with regards to texture filtering than the Radeon RX 590. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon RX 590		211536 Mtexels/sec
	Difference: 67224 (32%)

Pixel Rate

The GeForce RTX 2080 is quite a bit (more or less 106%) faster with regards to anti-aliasing than the Radeon RX 590, and also will be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2080		96960 Mpixels/sec
Radeon RX 590		47008 Mpixels/sec
	Difference: 49952 (106%)

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 (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the bus width by its memory clock speed. If it uses DDR RAM, it 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 anti-aliasing, High Dynamic Range and high resolutions.

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

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