GeForce RTX 2070 Super vs Radeon RX 580

Intro

Compare that to the Radeon RX 580, which has a clock speed of 1257 MHz and a GDDR5 memory frequency of 2000 MHz. It also makes use of a 256-bit bus, and uses a 14 nm design. It is made up of 2304 SPUs, 144 TAUs, and 32 Raster Operation Units.

Radeon RX 580		262144 MB/sec
	Difference: 196608 (75%)

Texel Rate

The GeForce RTX 2070 Super is a lot (more or less 42%) faster with regards to anisotropic filtering than the Radeon RX 580. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
Radeon RX 580		181008 Mtexels/sec
	Difference: 75792 (42%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2070 Super is the winner, by a large margin. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon RX 580		40224 Mpixels/sec
	Difference: 62496 (155%)

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 MB per second) that can be moved past the external memory interface in one second. It's worked out by multiplying the bus width by its memory speed. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are applied per second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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