Radeon R9 380 2G vs Radeon RX 5600 XT

Intro

Compare all of that to the Radeon RX 5600 XT, which uses a 7 nm design. AMD has clocked the core frequency at 1375 MHz. The GDDR6 RAM works at a speed of 1500 MHz on this particular model. It features 2304 SPUs as well as 144 Texture Address Units and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon R9 380 2G		190 Watts
	Difference: 30 Watts (19%)

Memory Bandwidth

In theory, the Radeon RX 5600 XT is 89% faster than the Radeon R9 380 2G in general, because of its higher bandwidth. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon R9 380 2G		182400 MB/sec
	Difference: 161664 (89%)

Texel Rate

The Radeon RX 5600 XT will be quite a bit (more or less 82%) faster with regards to anisotropic filtering than the Radeon R9 380 2G. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R9 380 2G		108640 Mtexels/sec
	Difference: 89360 (82%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5600 XT is a better choice, and very much so. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon R9 380 2G		31040 Mpixels/sec
	Difference: 56960 (184%)

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 largest amount of information (in units of MB per second) that can be transported over the external memory interface in one second. It is worked out by multiplying the interface width by its memory clock speed. If it uses DDR RAM, the result should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are processed in one 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 this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
