GeForce RTX 2080 SUPER vs Radeon R9 M395X

Intro

Compare those specs to the Radeon R9 M395X, which comes with GPU clock speed of 723 MHz, and 4096 MB of GDDR5 memory set to run at 1250 MHz through a 256-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 32 Raster Operation Units.

In theory, the GeForce RTX 2080 SUPER will be 217% faster than the Radeon R9 M395X overall, due to its higher bandwidth. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon R9 M395X		160000 MB/sec
	Difference: 347904 (217%)

Texel Rate

The GeForce RTX 2080 SUPER should be a lot (more or less 242%) more effective at anisotropic filtering than the Radeon R9 M395X. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R9 M395X		92544 Mtexels/sec
	Difference: 224256 (242%)

Pixel Rate

The GeForce RTX 2080 SUPER should be quite a bit (about 356%) more effective at anti-aliasing than the Radeon R9 M395X, and capable of handling higher screen resolutions better. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R9 M395X		23136 Mpixels/sec
	Difference: 82464 (356%)

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 (measured in MB per second) that can be transferred over the external memory interface in a second. It is calculated by multiplying the card's bus width by the speed of its memory. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's 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 can be applied per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
