GeForce 920M vs Radeon RX 7900 XT

Intro

Compare all of that to the Radeon RX 7900 XT, which features a GPU core clock speed of 1500 MHz, and 20480 MB of GDDR6 memory running at 2500 MHz through a 320-bit bus. It also is made up of 5376 Stream Processors, 336 Texture Address Units, and 192 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the Radeon RX 7900 XT should perform much faster than the GeForce 920M in general. (explain)

Radeon RX 7900 XT		819200 MB/sec
GeForce 920M		14400 MB/sec
	Difference: 804800 (5589%)

Texel Rate

The Radeon RX 7900 XT is a lot (more or less 1551%) better at anisotropic filtering than the GeForce 920M. (explain)

Radeon RX 7900 XT		504000 Mtexels/sec
GeForce 920M		30528 Mtexels/sec
	Difference: 473472 (1551%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 7900 XT is superior to the GeForce 920M, and very much so. (explain)

Radeon RX 7900 XT		288000 Mpixels/sec
GeForce 920M		7632 Mpixels/sec
	Difference: 280368 (3674%)

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 maximum amount of data (measured in megabytes per second) that can be transferred over the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

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