GeForce GTX 660 Ti vs Radeon RX 6500 XT

Intro

Compare all of that to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has set the core frequency at 2200 MHz. The GDDR6 memory runs at a speed of 2250 MHz on this model. It features 1024 SPUs as well as 64 Texture Address Units and 32 Rasterization Operator Units.

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

Memory Bandwidth

As far as performance goes, the Radeon RX 6500 XT should theoretically be a small bit superior to 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 should be a lot (about 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 resolution is important to you, then the Radeon RX 6500 XT is superior to the GeForce GTX 660 Ti, 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: Bandwidth is the max amount of information (in units of megabytes per second) that can be transferred past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that can be processed per second. This 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 applied in a second.

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