GeForce RTX 3060 Ti vs Radeon RX 6650 XT

Intro

Compare those specs to the Radeon RX 6650 XT, which comes with GPU core speed of 2055 MHz, and 8192 MB of GDDR6 RAM set to run at 2190 MHz through a 128-bit bus. It also is comprised of 2048 Stream Processors, 128 Texture Address Units, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 6650 XT		176 Watts
GeForce RTX 3060 Ti		200 Watts
	Difference: 24 Watts (14%)

Memory Bandwidth

In theory, the Radeon RX 6650 XT is -100% faster than the GeForce RTX 3060 Ti in general, because of its higher data rate. (explain)

Radeon RX 6650 XT		287072 MB/sec
GeForce RTX 3060 Ti		(Unknown) MB/sec
	Difference: 287072 (-100%)

Texel Rate

The Radeon RX 6650 XT is much (more or less 23%) more effective at texture filtering than the GeForce RTX 3060 Ti. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce RTX 3060 Ti		214320 Mtexels/sec
	Difference: 48720 (23%)

Pixel Rate

The Radeon RX 6650 XT is a little bit (about 17%) better at full screen anti-aliasing than the GeForce RTX 3060 Ti, and should be capable of handling higher resolutions while still performing well. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce RTX 3060 Ti		112800 Mpixels/sec
	Difference: 18720 (17%)

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 max amount of data (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core speed of the card. 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 output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
