GeForce GTX Titan vs Radeon RX 6600 XT

Intro

Compare all that to the Radeon RX 6600 XT, which has a GPU core clock speed of 1968 MHz, and 8192 MB of GDDR6 memory running at 2000 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 64 Raster Operation Units.

Radeon RX 6600 XT		262144 MB/sec
	Difference: 26240 (10%)

Texel Rate

The Radeon RX 6600 XT should be much (approximately 34%) better at texture filtering than the GeForce GTX Titan. (explain)

Radeon RX 6600 XT		251904 Mtexels/sec
GeForce GTX Titan		187488 Mtexels/sec
	Difference: 64416 (34%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6600 XT is a better choice, by far. (explain)

Radeon RX 6600 XT		125952 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 85776 (214%)

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 information (counted in megabytes per second) that can be moved past the external memory interface in one second. It's calculated by multiplying the bus width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
