GeForce 825M vs Radeon RX 6900 XT

Intro

Compare that to the Radeon RX 6900 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1825 MHz. The GDDR6 memory runs at a speed of 2000 MHz on this specific card. It features 5120 SPUs along with 320 Texture Address Units and 128 ROPs.

GeForce 825M		33 Watts
Radeon RX 6900 XT		300 Watts
	Difference: 267 Watts (809%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 6900 XT should perform much faster than the GeForce 825M in general. (explain)

Radeon RX 6900 XT		524288 MB/sec
GeForce 825M		14400 MB/sec
	Difference: 509888 (3541%)

Texel Rate

The Radeon RX 6900 XT will be much (more or less 4194%) better at anisotropic filtering than the GeForce 825M. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
GeForce 825M		13600 Mtexels/sec
	Difference: 570400 (4194%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is the winner, by far. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
GeForce 825M		6800 Mpixels/sec
	Difference: 226800 (3335%)

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 (in units of MB per second) that can be moved across the external memory interface in one second. It's calculated by multiplying the card's bus width by the speed of its memory. If it uses DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, 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 texture units by the core speed of the chip. The better the texel rate, the better the card will be at 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 the video card can possibly record to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
