Radeon R9 380 2G vs Radeon RX 6500 XT

Intro

Compare those specs to the Radeon RX 6500 XT, which uses a 6 nm design. AMD has clocked the core speed at 2200 MHz. The GDDR6 memory is set to run at a frequency of 2250 MHz on this specific model. It features 1024 SPUs along with 64 Texture Address Units and 32 Rasterization Operator Units.

Radeon R9 380 2G		190 Watts
	Difference: 83 Watts (78%)

Memory Bandwidth

Theoretically speaking, the Radeon R9 380 2G is 24% faster than the Radeon RX 6500 XT overall, because of its greater bandwidth. (explain)

Radeon R9 380 2G		182400 MB/sec
Radeon RX 6500 XT		147456 MB/sec
	Difference: 34944 (24%)

Texel Rate

The Radeon RX 6500 XT will be much (more or less 30%) faster with regards to AF than the Radeon R9 380 2G. (explain)

Radeon RX 6500 XT		140800 Mtexels/sec
Radeon R9 380 2G		108640 Mtexels/sec
	Difference: 32160 (30%)

Pixel Rate

If using a high resolution is important to you, then the Radeon RX 6500 XT is superior to the Radeon R9 380 2G, and very much so. (explain)

Radeon RX 6500 XT		70400 Mpixels/sec
Radeon R9 380 2G		31040 Mpixels/sec
	Difference: 39360 (127%)

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 maximum amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it must be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher this number, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.

Pixel Rate: Pixel rate is the most pixels that the graphics chip could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour 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 rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
