Radeon R9 380 2G vs Radeon RX 6700 XT

Intro

Compare all of that to the Radeon RX 6700 XT, which features a core clock frequency of 2321 MHz and a GDDR6 memory speed of 2000 MHz. It also uses a 192-bit bus, and uses a 7 nm design. It is made up of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Radeon R9 380 2G		182400 MB/sec
	Difference: 210816 (116%)

Texel Rate

The Radeon RX 6700 XT should be quite a bit (more or less 242%) better at AF than the Radeon R9 380 2G. (explain)

Radeon RX 6700 XT		371360 Mtexels/sec
Radeon R9 380 2G		108640 Mtexels/sec
	Difference: 262720 (242%)

Pixel Rate

If using a high screen resolution is important to you, then the Radeon RX 6700 XT is the winner, by far. (explain)

Radeon RX 6700 XT		148544 Mpixels/sec
Radeon R9 380 2G		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 maximum amount of data (measured in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the card's interface width by its memory speed. If it uses DDR RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 number of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed per second.

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
