Theoretically speaking, the Radeon RX 5700 will be 91% faster than the Radeon R9 280 in general, due to its higher data rate. (explain)

Radeon RX 5700		458752 MB/sec
Radeon R9 280		240000 MB/sec
	Difference: 218752 (91%)

Texel Rate

The Radeon RX 5700 will be much (more or less 102%) faster with regards to anisotropic filtering than the Radeon R9 280. (explain)

Radeon RX 5700		210960 Mtexels/sec
Radeon R9 280		104496 Mtexels/sec
	Difference: 106464 (102%)

Pixel Rate

If running with a high resolution is important to you, then the Radeon RX 5700 is a better choice, by far. (explain)

Radeon RX 5700		93760 Mpixels/sec
Radeon R9 280		29856 Mpixels/sec
	Difference: 63904 (214%)

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 within a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the 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 speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
