GeForce RTX 2080 SUPER vs Radeon RX 470

Intro

Compare all of that to the Radeon RX 470, which comes with GPU core speed of 926 MHz, and 8192 MB of GDDR5 memory running at 1650 MHz through a 256-bit bus. It also features 2048 Stream Processors, 128 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 470		120 Watts
GeForce RTX 2080 SUPER		250 Watts
	Difference: 130 Watts (108%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 2080 SUPER should in theory be a lot superior to the Radeon RX 470 overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX 470		211200 MB/sec
	Difference: 296704 (140%)

Texel Rate

The GeForce RTX 2080 SUPER is much (about 167%) faster with regards to texture filtering than the Radeon RX 470. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon RX 470		118528 Mtexels/sec
	Difference: 198272 (167%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is a better choice, and very much so. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX 470		29632 Mpixels/sec
	Difference: 75968 (256%)

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 maximum amount of data (counted in megabytes per second) that can be moved over the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one 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. The number 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 filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
