GeForce RTX 3070 Ti vs Radeon RX 6650 XT

Intro

Compare those specs to the Radeon RX 6650 XT, which features core speeds of 2055 MHz on the GPU, and 2190 MHz on the 8192 MB of GDDR6 RAM. It features 2048 SPUs along with 128 TAUs and 64 Rasterization Operator Units.

Radeon RX 6650 XT		287072 MB/sec
	Difference: 335827 (117%)

Texel Rate

The GeForce RTX 3070 Ti should be a little bit (more or less 15%) better at AF than the Radeon RX 6650 XT. (explain)

GeForce RTX 3070 Ti		302400 Mtexels/sec
Radeon RX 6650 XT		263040 Mtexels/sec
	Difference: 39360 (15%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 3070 Ti is a better choice, though not by far. (explain)

GeForce RTX 3070 Ti		151200 Mpixels/sec
Radeon RX 6650 XT		131520 Mpixels/sec
	Difference: 19680 (15%)

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 data (counted in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines 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 is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
