GeForce RTX 2080 SUPER vs Radeon RX 460

Intro

Compare all of that to the Radeon RX 460, which comes with GPU core speed of 1090 MHz, and 4096 MB of GDDR5 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 TAUs, and 16 Raster Operation Units.

Radeon RX 460		61040 Mtexels/sec
	Difference: 255760 (419%)

Pixel Rate

The GeForce RTX 2080 SUPER is much (more or less 506%) more effective at anti-aliasing than the Radeon RX 460, and capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 460		17440 Mpixels/sec
	Difference: 88160 (506%)

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 megabytes per second) that can be transferred past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
