GeForce 920M vs Radeon RX 7900 XT

Intro

Compare those specifications to the Radeon RX 7900 XT, which uses a 5 nm design. AMD has clocked the core frequency at 1500 MHz. The GDDR6 RAM runs at a frequency of 2500 MHz on this model. It features 5376 SPUs along with 336 TAUs and 192 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the Radeon RX 7900 XT should be 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 should be quite a bit (more or less 1551%) more effective 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 the winner, by far. (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: Bandwidth is the max amount of data (in units of megabytes per second) that can be transferred past the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If the card has DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory per second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
