GeForce GTX 980 vs Radeon RX 6600

Intro

Compare all that to the Radeon RX 6600, which comes with a GPU core clock speed of 1626 MHz, and 8192 MB of GDDR6 RAM set to run at 1750 MHz through a 128-bit bus. It also features 1792 Stream Processors, 112 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX 980		144128 Mtexels/sec
	Difference: 37984 (26%)

Pixel Rate

The Radeon RX 6600 is quite a bit (more or less 44%) faster with regards to AA than the GeForce GTX 980, and also will be able to handle higher screen resolutions better. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 980		72064 Mpixels/sec
	Difference: 32000 (44%)

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 moved across the external memory interface within a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. 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 output rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
