GeForce GTX 970M vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which features GPU core speed of 2200 MHz, and 4096 MB of GDDR6 RAM set to run at 2250 MHz through a 64-bit bus. It also is made up of 1024 SPUs, 64 TAUs, and 32 Raster Operation Units.

GeForce GTX 970M		75 Watts
Radeon RX 6500 XT		107 Watts
	Difference: 32 Watts (43%)

Memory Bandwidth

The Radeon RX 6500 XT should theoretically perform quite a bit faster than the GeForce GTX 970M overall. (explain)

Radeon RX 6500 XT		147456 MB/sec
GeForce GTX 970M		96000 MB/sec
	Difference: 51456 (54%)

Texel Rate

The Radeon RX 6500 XT will be a lot (more or less 90%) better at texture filtering than the GeForce GTX 970M. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
GeForce GTX 970M		73920 Mtexels/sec
	Difference: 66880 (90%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 6500 XT is superior to the GeForce GTX 970M, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
GeForce GTX 970M		44352 Mpixels/sec
	Difference: 26048 (59%)

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 information (measured in MB per second) that can be transported over the external memory interface in a second. It is worked out by multiplying the interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that are processed in one second. This is calculated by multiplying the total texture units of the card 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
