GeForce GTX 980M vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has set the core frequency at 2200 MHz. The GDDR6 memory works at a frequency of 2250 MHz on this card. It features 1024 SPUs along with 64 Texture Address Units and 32 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980M		100 Watts
Radeon RX 6500 XT		107 Watts
	Difference: 7 Watts (7%)

Memory Bandwidth

Performance-wise, the Radeon RX 6500 XT should in theory be just a bit superior to the GeForce GTX 980M in general. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 980M		128000 MB/sec
	Difference: 19456 (15%)

Texel Rate

The Radeon RX 6500 XT will be quite a bit (approximately 41%) more effective at anisotropic filtering than the GeForce GTX 980M. (explain)

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

Pixel Rate

The Radeon RX 6500 XT should be a little bit (more or less 6%) faster with regards to AA than the GeForce GTX 980M, and also will be able to handle higher resolutions more effectively. (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.

Specifications

Memory Bandwidth: Bandwidth is the largest amount of data (counted in megabytes per second) that can be transported over the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the video card could possibly write to the local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount 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 drawing the pixels (image) on the screen. The actual pixel fill rate is also dependant on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
