GeForce GTX 980 Ti vs Radeon RX 6600

Intro

Compare those specifications to the Radeon RX 6600, which has clock speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 RAM. It features 1792 SPUs along with 112 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6600		132 Watts
GeForce GTX 980 Ti		250 Watts
	Difference: 118 Watts (89%)

Memory Bandwidth

The GeForce GTX 980 Ti should in theory perform much faster than the Radeon RX 6600 in general. (explain)

GeForce GTX 980 Ti		336000 MB/sec
Radeon RX 6600		229376 MB/sec
	Difference: 106624 (46%)

Texel Rate

The Radeon RX 6600 is just a bit (more or less 3%) faster with regards to texture filtering than the GeForce GTX 980 Ti. (explain)

Radeon RX 6600		182112 Mtexels/sec
GeForce GTX 980 Ti		176000 Mtexels/sec
	Difference: 6112 (3%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6600 is the winner, but it probably won't make a huge difference. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX 980 Ti		96000 Mpixels/sec
	Difference: 8064 (8%)

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 largest amount of data (counted in MB per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, 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 applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
