GeForce GTX 660 Ti vs Radeon RX 6500 XT

Intro

Compare those specifications to the Radeon RX 6500 XT, which has GPU clock speed of 2200 MHz, and 4096 MB of GDDR6 RAM set to run at 2250 MHz through a 64-bit bus. It also features 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The Radeon RX 6500 XT should in theory perform a little bit faster than the GeForce GTX 660 Ti overall. (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 a lot (approximately 37%) more effective at anisotropic 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 screen resolution is important to you, then the Radeon RX 6500 XT is a better choice, and very much so. (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: Memory bandwidth is the maximum amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by its memory clock speed. If it uses DDR type RAM, it must be multiplied by 2 again. If it uses 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
