GeForce GTX 970 vs Radeon RX 6600

Intro

Compare that to the Radeon RX 6600, which has GPU clock speed of 1626 MHz, and 8192 MB of GDDR6 memory set to run at 1750 MHz through a 128-bit bus. It also is made up of 1792 SPUs, 112 Texture Address Units, and 64 ROPs.

The Radeon RX 6600 will be much (about 67%) better at anisotropic filtering than the GeForce GTX 970. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 970		109200 Mtexels/sec
	Difference: 72912 (67%)

Pixel Rate

The Radeon RX 6600 will be a lot (more or less 55%) better at FSAA than the GeForce GTX 970, and should be able to handle higher screen resolutions without losing too much performance. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 970		67200 Mpixels/sec
	Difference: 36864 (55%)

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 max amount of information (measured in MB per second) that can be moved over the external memory interface in one second. It is worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 texture map elements (texels) that are processed per second. This number is worked out by multiplying the total number of texture units by the core clock speed of the chip. The better the texel rate, the better the video 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 maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines 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 also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
