GeForce RTX 2080 SUPER vs Radeon R9 M385X

Intro

Compare those specifications to the Radeon R9 M385X, which makes use of a 28 nm design. AMD has clocked the core speed at 1100 MHz. The GDDR5 memory works at a speed of 1500 MHz on this model. It features 896 SPUs as well as 56 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the GeForce RTX 2080 SUPER will be 429% faster than the Radeon R9 M385X overall, because of its higher bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 411904 (429%)

Texel Rate

The GeForce RTX 2080 SUPER will be much (about 414%) faster with regards to anisotropic filtering than the Radeon R9 M385X. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 255200 (414%)

Pixel Rate

The GeForce RTX 2080 SUPER is a lot (about 500%) more effective at AA than the Radeon R9 M385X, and should be able to handle higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 88000 (500%)

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 (measured in megabytes per second) that can be moved over the external memory interface in a second. The number is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics 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 maximum number of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
