GeForce GTX 970M vs Radeon RX 5700 XT

Intro

Compare those specifications to the Radeon RX 5700 XT, which makes use of a 7 nm design. AMD has set the core frequency at 1605 MHz. The GDDR6 RAM is set to run at a speed of 1750 MHz on this specific model. It features 2560 SPUs along with 160 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970M		75 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 150 Watts (200%)

Memory Bandwidth

Theoretically, the Radeon RX 5700 XT should be quite a bit faster than the GeForce GTX 970M in general. (explain)

Radeon RX 5700 XT		458752 MB/sec
GeForce GTX 970M		96000 MB/sec
	Difference: 362752 (378%)

Texel Rate

The Radeon RX 5700 XT should be quite a bit (more or less 247%) more effective at texture filtering than the GeForce GTX 970M. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
GeForce GTX 970M		73920 Mtexels/sec
	Difference: 182880 (247%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 5700 XT is the winner, by a large margin. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
GeForce GTX 970M		44352 Mpixels/sec
	Difference: 58368 (132%)

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 maximum amount of data (counted in MB per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total amount of texture units by the core speed of the chip. The better the texel rate, the better the 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 that the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the core speed of the card. 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 many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
