GeForce GTX 980M vs Radeon RX 6500 XT

Intro

The GeForce GTX 980M makes use of a 28 nm design. nVidia has set the core speed at 1038 MHz. The GDDR5 memory runs at a frequency of 1000 MHz on this model. It features 1536 SPUs along with 96 Texture Address Units and 64 ROPs.

Compare those specs to the Radeon RX 6500 XT, which makes use of a 6 nm design. AMD has set the core speed at 2200 MHz. The GDDR6 RAM runs at a speed of 2250 MHz on this specific model. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.

GeForce GTX 980M 128000 MB/sec
Difference: 19456 (15%)

Texel Rate

The Radeon RX 6500 XT is quite a bit (more or less 41%) better at AF than the GeForce GTX 980M. (explain)

Radeon RX 6500 XT 140800 Mtexels/sec
GeForce GTX 980M 99648 Mtexels/sec
Difference: 41152 (41%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6500 XT is superior to the GeForce GTX 980M, but not by far. (explain)

Radeon RX 6500 XT 70400 Mpixels/sec
GeForce GTX 980M 66432 Mpixels/sec
Difference: 3968 (6%)

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.

Memory Bandwidth: Bandwidth is the largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by the speed of its memory. If the card has DDR type 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 anti-aliasing, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
