GeForce GTX 660 Ti vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which comes with clock speeds of 2200 MHz on the GPU, and 2250 MHz on the 4096 MB of GDDR6 memory. It features 1024 SPUs as well as 64 TAUs and 32 Rasterization Operator Units.

GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 38320 (37%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6500 XT is the winner, 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 max amount of data (measured in megabytes per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly write to its local memory in one second - measured in millions of pixels per second. The figure 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 filling the screen with pixels (the image). The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
