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

Texel Rate

The Radeon RX 6700 XT should be a lot (more or less 255%) more effective at texture filtering than the Radeon R9 280. (explain)

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

Pixel Rate

The Radeon RX 6700 XT will be much (approximately 398%) more effective at AA than the Radeon R9 280, and also will be able to handle higher screen resolutions without slowing down too much. (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 largest amount of information (measured in MB per second) that can be transported past the external memory interface within a second. The number is worked out by multiplying the interface width by its memory speed. If it uses DDR type RAM, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 texture map elements (texels) that are applied per 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 the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of ROPs by the clock speed of the card. 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 fill rate also depends on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
