Radeon R9 380 4G vs Radeon RX 5600 XT

Intro

Compare those specs to the Radeon RX 5600 XT, which makes use of a 7 nm design. AMD has set the core speed at 1375 MHz. The GDDR6 RAM is set to run at a frequency of 1500 MHz on this particular model. It features 2304 SPUs along with 144 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon R9 380 4G		190 Watts
	Difference: 30 Watts (19%)

Memory Bandwidth

Theoretically speaking, the Radeon RX 5600 XT will be 89% faster than the Radeon R9 380 4G in general, because of its greater data rate. (explain)

Radeon RX 5600 XT		344064 MB/sec
Radeon R9 380 4G		182400 MB/sec
	Difference: 161664 (89%)

Texel Rate

The Radeon RX 5600 XT should be a lot (more or less 82%) more effective at AF than the Radeon R9 380 4G. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R9 380 4G		108640 Mtexels/sec
	Difference: 89360 (82%)

Pixel Rate

The Radeon RX 5600 XT will be quite a bit (more or less 184%) better at AA than the Radeon R9 380 4G, and also should be able to handle higher resolutions without slowing down too much. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon R9 380 4G		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: Memory bandwidth is the largest amount of information (counted in megabytes per second) that can be transported over the external memory interface in a second. It's worked out by multiplying the card's interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip can possibly write to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel output rate also depends on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
