GeForce GTX 980 vs Radeon RX 6600

Intro

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

Radeon RX 6600		132 Watts
GeForce GTX 980		165 Watts
	Difference: 33 Watts (25%)

Memory Bandwidth

Performance-wise, the Radeon RX 6600 should in theory be a little bit better than the GeForce GTX 980 overall. (explain)

Radeon RX 6600		229376 MB/sec
GeForce GTX 980		224000 MB/sec
	Difference: 5376 (2%)

Texel Rate

The Radeon RX 6600 is quite a bit (approximately 26%) more effective at texture filtering than the GeForce GTX 980. (explain)

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

Pixel Rate

The Radeon RX 6600 should be a lot (approximately 44%) more effective at anti-aliasing than the GeForce GTX 980, and should be able to handle higher resolutions without slowing down too much. (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 (in units of megabytes per second) that can be transferred across the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the bandwidth is, the better 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 processed in one second. This number is calculated by multiplying the total number of texture units by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the clock 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 quite a few other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
