GeForce RTX 3060 Ti vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which has a core clock speed of 2055 MHz and a GDDR6 memory frequency of 2190 MHz. It also uses a 128-bit bus, and uses a 7 nm design. It features 2048 SPUs, 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

The Radeon RX 6650 XT, in theory, should be a bit faster than the GeForce RTX 3060 Ti in general. (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 a lot (about 23%) better 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

If using lots of anti-aliasing is important to you, then the Radeon RX 6650 XT is superior to the GeForce RTX 3060 Ti, though not by far. (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 largest amount of data (in units of megabytes per second) that can be moved across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, HDR 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 amount of texture units by the core speed of the chip. The higher the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
