GeForce RTX 2080 SUPER vs Radeon RX 470

Intro

Compare those specifications to the Radeon RX 470, which uses a 14 nm design. AMD has set the core speed at 926 MHz. The GDDR5 RAM works at a frequency of 1650 MHz on this specific model. It features 2048 SPUs along with 128 TAUs and 32 Rasterization Operator 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

In theory, the GeForce RTX 2080 SUPER is 140% faster than the Radeon RX 470 in general, because of its higher bandwidth. (explain)

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

Texel Rate

The GeForce RTX 2080 SUPER should be a lot (approximately 167%) better at 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

The GeForce RTX 2080 SUPER will be quite a bit (more or less 256%) more effective at FSAA than the Radeon RX 470, and will be able to handle higher screen resolutions without slowing down too much. (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: Bandwidth is the maximum amount of data (measured in megabytes per second) that can be transported past the external memory interface in a second. It's calculated by multiplying the bus width by its memory speed. If the card has DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the 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 the video card could possibly write to the local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the clock speed of the card. 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 rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
