Radeon R9 380X vs Radeon RX 5600 XT

Intro

Compare all that to the Radeon RX 5600 XT, which has clock speeds of 1375 MHz on the GPU, and 1500 MHz on the 6144 MB of GDDR6 RAM. It features 2304 SPUs along with 144 Texture Address Units and 64 ROPs.

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

Memory Bandwidth

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

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

Texel Rate

The Radeon RX 5600 XT will be much (approximately 59%) faster with regards to texture filtering than the Radeon R9 380X. (explain)

Radeon RX 5600 XT		198000 Mtexels/sec
Radeon R9 380X		124160 Mtexels/sec
	Difference: 73840 (59%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5600 XT is the winner, by far. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon R9 380X		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 max amount of data (measured in MB per second) that can be transferred over the external memory interface in one second. It is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR memory, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied per second. This is worked out by multiplying the total number of texture units by the core speed of the chip. The higher 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 in a second.

Pixel Rate: Pixel rate is the most pixels the graphics card can possibly write to its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
