GeForce GTX Titan Black vs Radeon RX 6800 XT

Intro

Compare those specifications to the Radeon RX 6800 XT, which has GPU core speed of 1825 MHz, and 16384 MB of GDDR6 memory set to run at 2000 MHz through a 256-bit bus. It also features 4608 Stream Processors, 288 Texture Address Units, and 128 Raster Operation Units.

GeForce GTX Titan Black		213360 Mtexels/sec
	Difference: 312240 (146%)

Pixel Rate

The Radeon RX 6800 XT should be much (about 447%) better at FSAA than the GeForce GTX Titan Black, and also should be able to handle higher resolutions better. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce GTX Titan Black		42672 Mpixels/sec
	Difference: 190928 (447%)

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 (counted in megabytes 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, it should be multiplied by 2 once 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 AA, 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 number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
