GeForce RTX 2080 SUPER vs Radeon RX 470

Intro

Compare those specs to the Radeon RX 470, which makes use of a 14 nm design. AMD has set the core frequency at 926 MHz. The GDDR5 RAM works at a speed of 1650 MHz on this specific card. 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

Theoretically speaking, the GeForce RTX 2080 SUPER is 140% quicker than the Radeon RX 470 in general, because of its greater data rate. (explain)

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

Texel Rate

The GeForce RTX 2080 SUPER will be a lot (more or less 167%) more effective 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 is quite a bit (more or less 256%) faster with regards to AA than the Radeon RX 470, and also capable of handling higher resolutions without losing too much performance. (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 (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics 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 amount of pixels that the graphics chip could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
