GeForce GTX Titan vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which comes with GPU clock speed of 2055 MHz, and 8192 MB of GDDR6 memory running at 2190 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 Texture Address Units, and 64 Raster Operation Units.

GeForce GTX Titan		187488 Mtexels/sec
	Difference: 75552 (40%)

Pixel Rate

The Radeon RX 6650 XT will be quite a bit (approximately 227%) better at FSAA than the GeForce GTX Titan, and will be able to handle higher resolutions without losing too much performance. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX Titan		40176 Mpixels/sec
	Difference: 91344 (227%)

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 maximum amount of information (counted in megabytes per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster 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 processed in one second. This number is calculated by multiplying the total texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
