GeForce GTX 980 Ti vs Radeon RX 6600

Intro

Compare all of that to the Radeon RX 6600, which features core clock speeds of 1626 MHz on the GPU, and 1750 MHz on the 8192 MB of GDDR6 memory. It features 1792 SPUs as well as 112 TAUs 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 theoretically perform much faster than the Radeon RX 6600 overall. (explain)

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

Texel Rate

The Radeon RX 6600 should be a little bit (about 3%) better at 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 running with lots of anti-aliasing is important to you, then the Radeon RX 6600 is a better choice, though not by far. (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 max amount of information (measured in megabytes per second) that can be moved across the external memory interface in a second. The number is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster 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 amount of texture map elements (texels) that can be processed per second. This number is worked out by multiplying the total number of texture units of the card 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 in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the max fill rate.
