GeForce GTX 560 Ti 448 vs Radeon RX 6800 XT

Intro

Compare all that to the Radeon RX 6800 XT, which features a core clock frequency of 1825 MHz and a GDDR6 memory frequency of 2000 MHz. It also uses a 256-bit memory bus, and uses a 7 nm design. It is comprised of 4608 SPUs, 288 TAUs, and 128 Raster Operation Units.

GeForce GTX 560 Ti 448		144000 MB/sec
	Difference: 380288 (264%)

Texel Rate

The Radeon RX 6800 XT is quite a bit (approximately 1182%) more effective at anisotropic filtering than the GeForce GTX 560 Ti 448. (explain)

Radeon RX 6800 XT		525600 Mtexels/sec
GeForce GTX 560 Ti 448		40992 Mtexels/sec
	Difference: 484608 (1182%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6800 XT is a better choice, and very much so. (explain)

Radeon RX 6800 XT		233600 Mpixels/sec
GeForce GTX 560 Ti 448		29280 Mpixels/sec
	Difference: 204320 (698%)

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 (in units of MB per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core 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 many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
