GeForce GTX Titan X vs Radeon RX 6600

Intro

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

Radeon RX 6600		182112 Mtexels/sec
	Difference: 9888 (5%)

Pixel Rate

The Radeon RX 6600 should be a small bit (more or less 8%) better at FSAA than the GeForce GTX Titan X, and also should be capable of handling higher resolutions more effectively. (explain)

Radeon RX 6600		104064 Mpixels/sec
GeForce GTX Titan X		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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transferred across the external memory interface in a second. It's worked out by multiplying the interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
