GeForce RTX 3060 Ti vs Radeon RX 6800 XT

Intro

Compare all that to the Radeon RX 6800 XT, which comes with 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 is made up of 4608 Stream Processors, 288 TAUs, and 128 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 3060 Ti		200 Watts
Radeon RX 6800 XT		300 Watts
	Difference: 100 Watts (50%)

Memory Bandwidth

In theory, the Radeon RX 6800 XT will be -100% faster than the GeForce RTX 3060 Ti in general, because of its higher bandwidth. (explain)

Radeon RX 6800 XT		524288 MB/sec
GeForce RTX 3060 Ti		(Unknown) MB/sec
	Difference: 524288 (-100%)

Texel Rate

The Radeon RX 6800 XT should be quite a bit (more or less 145%) faster with regards to AF than the GeForce RTX 3060 Ti. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce RTX 3060 Ti		214320 Mtexels/sec
	Difference: 311280 (145%)

Pixel Rate

The Radeon RX 6800 XT should be quite a bit (approximately 107%) better at FSAA than the GeForce RTX 3060 Ti, and also will be able to handle higher resolutions more effectively. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce RTX 3060 Ti		112800 Mpixels/sec
	Difference: 120800 (107%)

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 megabytes per second) that can be transferred over the external memory interface within a second. It is worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once 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 high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total texture units by the core speed of the chip. The better the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many 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.
