GeForce GTX Titan vs Radeon RX 6600 XT

Intro

Compare all of that to the Radeon RX 6600 XT, which comes with GPU core speed of 1968 MHz, and 8192 MB of GDDR6 RAM set to run at 2000 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 ROPs.

GeForce GTX Titan		187488 Mtexels/sec
	Difference: 64416 (34%)

Pixel Rate

The Radeon RX 6600 XT will be much (about 214%) faster with regards to full screen anti-aliasing than the GeForce GTX Titan, and able to handle higher screen resolutions better. (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 maximum amount of information (in units of megabytes per second) that can be moved past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This figure is calculated by multiplying the total texture units of the card by the core clock 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 applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the core 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 rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
