Radeon R9 380X		182400 MB/sec
	Difference: 276352 (152%)

Texel Rate

The Radeon RX 5700 is much (more or less 70%) better at AF than the Radeon R9 380X. (explain)

Radeon RX 5700		210960 Mtexels/sec
Radeon R9 380X		124160 Mtexels/sec
	Difference: 86800 (70%)

Pixel Rate

The Radeon RX 5700 should be a lot (approximately 202%) more effective at AA than the Radeon R9 380X, and also will be capable of handling higher resolutions without losing too much performance. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon R9 380X		31040 Mpixels/sec
	Difference: 62720 (202%)

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 information (measured in megabytes per second) that can be moved past the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. If the card has DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are processed in one second. This number is worked out by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the graphics 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 most pixels the graphics card could possibly write to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the max fill rate.
