Radeon R9 M380 vs Radeon RX 5700 XT

Intro

Compare that to the Radeon RX 5700 XT, which makes use of a 7 nm design. AMD has clocked the core speed at 1605 MHz. The GDDR6 memory is set to run at a speed of 1750 MHz on this particular card. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically speaking, the Radeon RX 5700 XT should be 378% quicker than the Radeon R9 M380 in general, due to its greater bandwidth. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 362752 (378%)

Texel Rate

The Radeon RX 5700 XT is much (more or less 542%) faster with regards to anisotropic filtering than the Radeon R9 M380. (explain)

Radeon RX 5700 XT		256800 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 216800 (542%)

Pixel Rate

The Radeon RX 5700 XT should be quite a bit (about 542%) better at full screen anti-aliasing than the Radeon R9 M380, and will be capable of handling higher screen resolutions while still performing well. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 86720 (542%)

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 megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's bus width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the better the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that are processed in one second. This figure is calculated by multiplying the total texture units of the card by the core speed of the chip. The better this number, the better the graphics 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 its local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour 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, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
