The GeForce RTX 2070 Super should be a lot (more or less 136%) better at AF than the Radeon R9 380 4G. (explain)

GeForce RTX 2070 Super		256800 Mtexels/sec
Radeon R9 380 4G		108640 Mtexels/sec
	Difference: 148160 (136%)

Pixel Rate

The GeForce RTX 2070 Super is quite a bit (more or less 231%) better at anti-aliasing than the Radeon R9 380 4G, and should be capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon R9 380 4G		31040 Mpixels/sec
	Difference: 71680 (231%)

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: Memory bandwidth is the largest amount of data (in units of MB per second) that can be moved past the external memory interface in one second. The number is worked out by multiplying the card's interface width by the speed of its memory. If it uses DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the card's memory bandwidth, 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 number of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video 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 maximum number of pixels that the graphics chip can possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Raster Operations Pipelines by the the core clock speed. 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 is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
