GeForce GTX 560 vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which comes with a core clock frequency of 1968 MHz and a GDDR6 memory frequency 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 perform much faster than the GeForce GTX 560 overall. (explain)

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

Texel Rate

The Radeon RX 6600 XT should be a lot (more or less 455%) more effective at texture 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 running with high levels of AA is important to you, then the Radeon RX 6600 XT is the winner, by far. (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: Memory bandwidth is the max amount of data (measured in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied in one second. This number is worked out by multiplying the total amount of 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 write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
