GeForce GTX 1660 Ti vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which features core clock speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs along with 128 Texture Address Units and 64 ROPs.

	Difference: 119040 (83%)

Pixel Rate

The Radeon RX 6650 XT will be much (approximately 83%) more effective at AA than the GeForce GTX 1660 Ti, and also capable of handling higher screen resolutions without losing too much performance. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX 1660 Ti		72000 Mpixels/sec
	Difference: 59520 (83%)

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 largest amount of data (measured in megabytes per second) that can be transported over the external memory interface within a second. It is calculated by multiplying the bus 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 ANOTHER 2x. The higher the bandwidth is, 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 amount of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher 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 per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Render Output Units by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
