GeForce GTX 980M vs Radeon RX 5700

Intro

Compare those specifications to the Radeon RX 5700, which comes with GPU core speed of 1465 MHz, and 8096 MB of GDDR6 memory set to run at 1750 MHz through a 256-bit bus. It also is comprised of 2304 SPUs, 144 TAUs, and 64 ROPs.

GeForce GTX 980M		128000 MB/sec
	Difference: 330752 (258%)

Texel Rate

The Radeon RX 5700 is quite a bit (about 112%) more effective at AF than the GeForce GTX 980M. (explain)

Radeon RX 5700		210960 Mtexels/sec
GeForce GTX 980M		99648 Mtexels/sec
	Difference: 111312 (112%)

Pixel Rate

If using high levels of AA is important to you, then the Radeon RX 5700 is superior to the GeForce GTX 980M, by a large margin. (explain)

Radeon RX 5700		93760 Mpixels/sec
GeForce GTX 980M		66432 Mpixels/sec
	Difference: 27328 (41%)

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 (counted in megabytes per second) that can be transferred over the external memory interface in one second. It is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that can be processed per second. This figure is worked out 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 processed per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number 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 filling the screen with pixels (the image). The actual pixel output rate also depends on lots of 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.
