GeForce GTX 660 Ti vs Radeon RX 6600

Intro

Compare those specs to the Radeon RX 6600, which uses a 7 nm design. AMD has clocked the core frequency at 1626 MHz. The GDDR6 memory works at a speed of 1750 MHz on this particular card. It features 1792 SPUs as well as 112 Texture Address Units and 64 ROPs.

GeForce GTX 660 Ti		102480 Mtexels/sec
	Difference: 79632 (78%)

Pixel Rate

The Radeon RX 6600 will be a lot (approximately 374%) faster with regards to AA than the GeForce GTX 660 Ti, and will be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 660 Ti		21960 Mpixels/sec
	Difference: 82104 (374%)

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 transferred over the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, 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 maximum amount of pixels the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
