GeForce GTX 1070 vs Radeon RX 6650 XT

Intro

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

Texel Rate

The Radeon RX 6650 XT is quite a bit (about 46%) more effective at AF than the GeForce GTX 1070. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce GTX 1070		180720 Mtexels/sec
	Difference: 82320 (46%)

Pixel Rate

The Radeon RX 6650 XT should be a lot (approximately 36%) more effective at FSAA than the GeForce GTX 1070, and will be capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce GTX 1070		96384 Mpixels/sec
	Difference: 35136 (36%)

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 max amount of data (counted in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
