Radeon R9 280		240000 MB/sec
	Difference: 153216 (64%)

Texel Rate

The Radeon RX 6700 XT is a lot (more or less 255%) more effective at AF than the Radeon R9 280. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 280		104496 Mtexels/sec
	Difference: 266864 (255%)

Pixel Rate

If running with a high screen resolution is important to you, then the Radeon RX 6700 XT is a better choice, and very much so. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 280		29856 Mpixels/sec
	Difference: 118688 (398%)

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 max amount of information (counted in megabytes per second) that can be transferred past the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better 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 can be processed per second. This is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of ROPs by the clock speed of the card. 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 also depends on many other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the maximum fill rate.
