GeForce GTX 980 Ti vs Radeon RX 6800

Intro

Compare those specifications to the Radeon RX 6800, which has GPU core speed of 1700 MHz, and 16384 MB of GDDR6 RAM set to run at 2000 MHz through a 256-bit bus. It also features 3840 Stream Processors, 240 TAUs, and 96 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The Radeon RX 6800 should theoretically perform quite a bit faster than the GeForce GTX 980 Ti in general. (explain)

Radeon RX 6800		524288 MB/sec
GeForce GTX 980 Ti		336000 MB/sec
	Difference: 188288 (56%)

Texel Rate

The Radeon RX 6800 will be quite a bit (approximately 132%) more effective at texture filtering than the GeForce GTX 980 Ti. (explain)

Radeon RX 6800		408000 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 232000 (132%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6800 is the winner, by a large margin. (explain)

Radeon RX 6800		163200 Mpixels/sec
GeForce GTX 980 Ti		96000 Mpixels/sec
	Difference: 67200 (70%)

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
