GeForce GTX 660 Ti vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has clocked the core speed at 2200 MHz. The GDDR6 RAM works at a frequency of 2250 MHz on this particular card. It features 1024 SPUs along with 64 TAUs and 32 Rasterization Operator Units.

Radeon RX 6500 XT		107 Watts
GeForce GTX 660 Ti		150 Watts
	Difference: 43 Watts (40%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6500 XT is 2% quicker than the GeForce GTX 660 Ti overall, because of its higher data rate. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 660 Ti		144000 MB/sec
	Difference: 3456 (2%)

Texel Rate

The Radeon RX 6500 XT will be much (approximately 37%) better at texture filtering than the GeForce GTX 660 Ti. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 38320 (37%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6500 XT is a better choice, by far. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 48440 (221%)

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 maximum amount of data (counted in megabytes per second) that can be moved across the external memory interface in a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 can be processed in one second. This number is calculated by multiplying the total number of texture units by the core clock 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 processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the card's clock speed. 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 rate also depends on quite a few other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
