The Radeon RX 6700 XT will be much (more or less 242%) better at texture filtering than the Radeon R9 380 4G. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 380 4G		108640 Mtexels/sec
	Difference: 262720 (242%)

Pixel Rate

The Radeon RX 6700 XT will be quite a bit (approximately 379%) better at anti-aliasing than the Radeon R9 380 4G, and also capable of handling higher screen resolutions without slowing down too much. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 380 4G		31040 Mpixels/sec
	Difference: 117504 (379%)

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 data (measured in megabytes per second) that can be transported across the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR type memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The higher the texel rate, 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 can possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
