Power Usage and Theoretical Benchmarks

Memory Bandwidth

Performance-wise, the GeForce RTX 2080 Ti should in theory be a lot superior to the Radeon R9 M385X overall. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 534784 (557%)

Texel Rate

The GeForce RTX 2080 Ti should be a lot (more or less 496%) faster with regards to texture filtering than the Radeon R9 M385X. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 305600 (496%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 2080 Ti is a better choice, by far. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 101200 (575%)

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 information (in units of megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range 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 amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the amount 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 also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the max fill rate.
