GeForce RTX 2070 vs Radeon RX 6650 XT

Intro

Compare all of that to the Radeon RX 6650 XT, which comes with a GPU core clock speed of 2055 MHz, and 8192 MB of GDDR6 RAM running at 2190 MHz through a 128-bit bus. It also is comprised of 2048 SPUs, 128 TAUs, and 64 ROPs.

Radeon RX 6650 XT		287072 MB/sec
	Difference: 171680 (60%)

Texel Rate

The Radeon RX 6650 XT is much (about 30%) better at texture filtering than the GeForce RTX 2070. (explain)

Radeon RX 6650 XT		263040 Mtexels/sec
GeForce RTX 2070		203040 Mtexels/sec
	Difference: 60000 (30%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6650 XT is superior to the GeForce RTX 2070, and very much so. (explain)

Radeon RX 6650 XT		131520 Mpixels/sec
GeForce RTX 2070		90240 Mpixels/sec
	Difference: 41280 (46%)

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 largest amount of information (in units of megabytes per second) that can be transported over the external memory interface in one second. The number is calculated by multiplying the bus width by its memory clock speed. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This figure is calculated by multiplying the total amount of texture units by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip can possibly record to its local memory in one second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
