GeForce RTX 2080 SUPER vs Radeon RX 570

Intro

Compare those specs to the Radeon RX 570, which has core clock speeds of 1168 MHz on the GPU, and 1750 MHz on the 4096 MB of GDDR5 RAM. It features 2048 SPUs as well as 128 TAUs and 32 Rasterization Operator Units.

Radeon RX 570		229376 MB/sec
	Difference: 278528 (121%)

Texel Rate

The GeForce RTX 2080 SUPER is much (approximately 112%) better at AF than the Radeon RX 570. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 570		149504 Mtexels/sec
	Difference: 167296 (112%)

Pixel Rate

The GeForce RTX 2080 SUPER is quite a bit (more or less 183%) more effective at FSAA than the Radeon RX 570, and will be able to handle higher resolutions without losing too much performance. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 570		37376 Mpixels/sec
	Difference: 68224 (183%)

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 max amount of information (in units of MB per second) that can be transferred over the external memory interface within a second. It is calculated by multiplying the interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are applied per second. This figure is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the video 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 maximum number of pixels that the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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 - the lower the bandwidth is, the lower the ability to get to the max fill rate.
