GeForce GTX 1070 Ti vs Radeon RX 6650 XT

Intro

Compare all that to the Radeon RX 6650 XT, which has GPU clock speed of 2055 MHz, and 8192 MB of GDDR6 memory set to run at 2190 MHz through a 128-bit bus. It also is made up of 2048 Stream Processors, 128 TAUs, and 64 ROPs.

	Difference: 18776 (8%)

Pixel Rate

The Radeon RX 6650 XT is quite a bit (about 28%) faster with regards to anti-aliasing than the GeForce GTX 1070 Ti, and also will be able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX 1070 Ti		102848 Mpixels/sec
	Difference: 28672 (28%)

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 megabytes per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
