GeForce RTX 2080 vs Radeon R9 M385X

Intro

Compare those specs to the Radeon R9 M385X, which features GPU clock speed of 1100 MHz, and 4096 MB of GDDR5 RAM set to run at 1500 MHz through a 128-bit bus. It also is made up of 896 SPUs, 56 Texture Address Units, and 16 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce RTX 2080 should in theory be quite a bit faster than the Radeon R9 M385X overall. (explain)

GeForce RTX 2080		458752 MB/sec
Radeon R9 M385X		96000 MB/sec
	Difference: 362752 (378%)

Texel Rate

The GeForce RTX 2080 should be much (approximately 353%) more effective at texture filtering than the Radeon R9 M385X. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon R9 M385X		61600 Mtexels/sec
	Difference: 217160 (353%)

Pixel Rate

If using high levels of AA is important to you, then the GeForce RTX 2080 is the winner, and very much so. (explain)

GeForce RTX 2080		96960 Mpixels/sec
Radeon R9 M385X		17600 Mpixels/sec
	Difference: 79360 (451%)

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 MB per second) that can be transferred over the external memory interface within a second. The number is calculated by multiplying the bus width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling 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 record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
