Radeon R9 380X		182400 MB/sec
	Difference: 407424 (223%)

Texel Rate

The Radeon RX 6950 XT should be much (about 396%) better at AF than the Radeon R9 380X. (explain)

Radeon RX 6950 XT		616000 Mtexels/sec
Radeon R9 380X		124160 Mtexels/sec
	Difference: 491840 (396%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 6950 XT is a better choice, by a large margin. (explain)

Radeon RX 6950 XT		246400 Mpixels/sec
Radeon R9 380X		31040 Mpixels/sec
	Difference: 215360 (694%)

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 maximum amount of information (in units of MB per second) that can be moved over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total 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 handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
