GeForce RTX 2080 vs Radeon RX 560

Intro

Compare all of that to the Radeon RX 560, which makes use of a 14 nm design. AMD has set the core frequency at 1175 MHz. The GDDR5 memory works at a speed of 1750 MHz on this particular card. It features 1024 SPUs along with 64 TAUs and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 560		80 Watts
GeForce RTX 2080		215 Watts
	Difference: 135 Watts (169%)

Memory Bandwidth

As far as performance goes, the GeForce RTX 2080 should in theory be quite a bit superior to the Radeon RX 560 in general. (explain)

GeForce RTX 2080		458752 MB/sec
Radeon RX 560		114688 MB/sec
	Difference: 344064 (300%)

Texel Rate

The GeForce RTX 2080 will be quite a bit (about 271%) better at anisotropic filtering than the Radeon RX 560. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon RX 560		75200 Mtexels/sec
	Difference: 203560 (271%)

Pixel Rate

The GeForce RTX 2080 will be a lot (approximately 416%) better at full screen anti-aliasing than the Radeon RX 560, and also should be able to handle higher resolutions without losing too much performance. (explain)

GeForce RTX 2080		96960 Mpixels/sec
Radeon RX 560		18800 Mpixels/sec
	Difference: 78160 (416%)

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 max amount of data (measured in megabytes per second) that can be transferred past the external memory interface within a second. The number is worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 number of texture map elements (texels) that are applied in one second. This figure is calculated by multiplying the total texture units by the core clock speed of the chip. The higher this number, the better the 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 can possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
