GeForce GTX 980 vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which has a clock frequency of 1626 MHz and a GDDR6 memory speed of 1750 MHz. It also uses a 128-bit memory bus, and uses a 7 nm design. It is comprised of 1792 SPUs, 112 TAUs, and 64 ROPs.

GeForce GTX 980		224000 MB/sec
	Difference: 5376 (2%)

Texel Rate

The Radeon RX 6600 will be much (more or less 26%) faster with regards to anisotropic filtering than the GeForce GTX 980. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 980		144128 Mtexels/sec
	Difference: 37984 (26%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 6600 is the winner, by far. (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 maximum amount of data (counted in MB per second) that can be moved over the external memory interface in one second. It's worked out by multiplying the card's bus width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be applied per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
