GeForce GTX 560 vs Radeon RX 6600 XT

Intro

Compare those specs to the Radeon RX 6600 XT, which comes with a clock speed of 1968 MHz and a GDDR6 memory speed of 2000 MHz. It also makes use of a 128-bit bus, and makes use of a 7 nm design. It is made up of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 560		150 Watts
Radeon RX 6600 XT		160 Watts
	Difference: 10 Watts (7%)

Memory Bandwidth

In theory, the Radeon RX 6600 XT should be 105% faster than the GeForce GTX 560 overall, due to its greater bandwidth. (explain)

Radeon RX 6600 XT		262144 MB/sec
GeForce GTX 560		128128 MB/sec
	Difference: 134016 (105%)

Texel Rate

The Radeon RX 6600 XT will be much (more or less 455%) more effective at anisotropic filtering than the GeForce GTX 560. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX 560		45360 Mtexels/sec
	Difference: 206544 (455%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 XT is the winner, and very much so. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX 560		25920 Mpixels/sec
	Difference: 100032 (386%)

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 (measured in megabytes per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's 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 number is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
