GeForce RTX 2080 SUPER vs Radeon R9 M295X

Intro

Compare those specs to the Radeon R9 M295X, which comes with a GPU core clock speed of 750 MHz, and 4096 MB of GDDR5 RAM set to run at 1375 MHz through a 256-bit bus. It also is made up of 2048 Stream Processors, 128 Texture Address Units, and 32 ROPs.

Radeon R9 M295X		176000 MB/sec
	Difference: 331904 (189%)

Texel Rate

The GeForce RTX 2080 SUPER will be much (approximately 230%) more effective at anisotropic filtering than the Radeon R9 M295X. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R9 M295X		96000 Mtexels/sec
	Difference: 220800 (230%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is the winner, by far. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R9 M295X		24000 Mpixels/sec
	Difference: 81600 (340%)

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 largest amount of information (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's interface width by the speed of its memory. If the card has DDR type RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one 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 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 the video card could possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
