GeForce GTX 970M vs Radeon RX 5500 XT

Intro

Compare those specs to the Radeon RX 5500 XT, which comes with a core clock speed of 1717 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 128-bit bus, and makes use of a 7 nm design. It is comprised of 1408 SPUs, 88 Texture Address Units, and 32 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 970M		75 Watts
Radeon RX 5500 XT		130 Watts
	Difference: 55 Watts (73%)

Memory Bandwidth

The Radeon RX 5500 XT should in theory be much faster than the GeForce GTX 970M in general. (explain)

Radeon RX 5500 XT		229376 MB/sec
GeForce GTX 970M		96000 MB/sec
	Difference: 133376 (139%)

Texel Rate

The Radeon RX 5500 XT should be quite a bit (approximately 104%) faster with regards to texture filtering than the GeForce GTX 970M. (explain)

Radeon RX 5500 XT		151096 Mtexels/sec
GeForce GTX 970M		73920 Mtexels/sec
	Difference: 77176 (104%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5500 XT is the winner, and very much so. (explain)

Radeon RX 5500 XT		54944 Mpixels/sec
GeForce GTX 970M		44352 Mpixels/sec
	Difference: 10592 (24%)

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 MB per second) that can be transported over the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR memory, the result should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the 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 in one second. This is calculated by multiplying the total texture units by the core clock speed of the chip. The higher the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
