Radeon R9 M380		96000 MB/sec
	Difference: 534784 (557%)

Texel Rate

The GeForce RTX 2080 Ti should be much (more or less 818%) better at AF than the Radeon R9 M380. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 327200 (818%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the GeForce RTX 2080 Ti is superior to the Radeon R9 M380, by far. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 102800 (643%)

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 max amount of data (counted in megabytes per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the bus width by its memory clock speed. In the case of DDR RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the the core clock speed. 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 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 maximum fill rate.
