GeForce GTX 980M vs Radeon RX 5600

Intro

Compare that to the Radeon RX 5600, which makes use of a 7 nm design. AMD has clocked the core speed at 1375 MHz. The GDDR6 memory is set to run at a speed of 1500 MHz on this specific model. It features 2048 SPUs as well as 128 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce GTX 980M		100 Watts
Radeon RX 5600		150 Watts
	Difference: 50 Watts (50%)

Memory Bandwidth

Performance-wise, the Radeon RX 5600 should in theory be much better than the GeForce GTX 980M overall. (explain)

Radeon RX 5600		294912 MB/sec
GeForce GTX 980M		128000 MB/sec
	Difference: 166912 (130%)

Texel Rate

The Radeon RX 5600 should be quite a bit (more or less 77%) better at anisotropic filtering than the GeForce GTX 980M. (explain)

Radeon RX 5600		176000 Mtexels/sec
GeForce GTX 980M		99648 Mtexels/sec
	Difference: 76352 (77%)

Pixel Rate

The Radeon RX 5600 should be a lot (approximately 32%) faster with regards to anti-aliasing than the GeForce GTX 980M, and also able to handle higher screen resolutions while still performing well. (explain)

Radeon RX 5600		88000 Mpixels/sec
GeForce GTX 980M		66432 Mpixels/sec
	Difference: 21568 (32%)

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 (in units of MB per second) that can be moved over the external memory interface in one second. The number is calculated by multiplying the interface width by its memory clock speed. If it uses DDR memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics chip could 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 drawing the pixels (image) on the screen. The actual pixel output rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
