GeForce RTX 2080 SUPER vs Radeon R9 M280X

Intro

Compare all that to the Radeon R9 M280X, which has a GPU core clock speed of 900 MHz, and 4096 MB of GDDR5 memory set to run at 1375 MHz through a 128-bit bus. It also is comprised of 896 SPUs, 56 Texture Address Units, and 16 ROPs.

Texel Rate

The GeForce RTX 2080 SUPER should be quite a bit (more or less 529%) faster with regards to texture filtering than the Radeon R9 M280X. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R9 M280X		50400 Mtexels/sec
	Difference: 266400 (529%)

Pixel Rate

If using a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is superior to the Radeon R9 M280X, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R9 M280X		14400 Mpixels/sec
	Difference: 91200 (633%)

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 largest amount of information (counted in megabytes per second) that can be transported past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If 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 amount of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

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