GeForce RTX 3080 Ti vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which comes with a core clock speed of 2200 MHz and a GDDR6 memory speed of 2250 MHz. It also makes use of a 64-bit bus, and makes use of a 6 nm design. It is made up of 1024 SPUs, 64 Texture Address Units, and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6500 XT		107 Watts
GeForce RTX 3080 Ti		350 Watts
	Difference: 243 Watts (227%)

Memory Bandwidth

Theoretically speaking, the GeForce RTX 3080 Ti is 534% quicker than the Radeon RX 6500 XT in general, because of its higher data rate. (explain)

GeForce RTX 3080 Ti		934297 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 786841 (534%)

Texel Rate

The GeForce RTX 3080 Ti should be a lot (more or less 210%) more effective at AF than the Radeon RX 6500 XT. (explain)

GeForce RTX 3080 Ti		436800 Mtexels/sec
Radeon RX 6500 XT		140800 Mtexels/sec
	Difference: 296000 (210%)

Pixel Rate

The GeForce RTX 3080 Ti is quite a bit (about 117%) better at anti-aliasing than the Radeon RX 6500 XT, and also capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 3080 Ti		152880 Mpixels/sec
Radeon RX 6500 XT		70400 Mpixels/sec
	Difference: 82480 (117%)

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 max amount of data (counted in megabytes per second) that can be transferred across the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines 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 fill rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
