GeForce GTX 660 Ti vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has clocked the core frequency at 2200 MHz. The GDDR6 memory works at a speed of 2250 MHz on this particular card. It features 1024 SPUs as well as 64 TAUs and 32 ROPs.

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

In theory, the Radeon RX 6500 XT should be 2% quicker than the GeForce GTX 660 Ti in general, because of its greater 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 should be a lot (about 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

The Radeon RX 6500 XT is quite a bit (approximately 221%) more effective at full screen anti-aliasing than the GeForce GTX 660 Ti, and also should be capable of handling higher resolutions while still performing well. (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 max amount of data (counted 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. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen 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 texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

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