Radeon R9 M380 vs Radeon RX 6900 XT

Intro

Compare all of that to the Radeon RX 6900 XT, which makes use of a 7 nm design. AMD has set the core speed at 1825 MHz. The GDDR6 RAM runs at a speed of 2000 MHz on this specific card. It features 5120 SPUs as well as 320 TAUs and 128 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

As far as performance goes, the Radeon RX 6900 XT should theoretically be a lot superior to the Radeon R9 M380 overall. (explain)

Radeon RX 6900 XT		524288 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 428288 (446%)

Texel Rate

The Radeon RX 6900 XT should be much (approximately 1360%) better at texture filtering than the Radeon R9 M380. (explain)

Radeon RX 6900 XT		584000 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 544000 (1360%)

Pixel Rate

If using lots of anti-aliasing is important to you, then the Radeon RX 6900 XT is the winner, by far. (explain)

Radeon RX 6900 XT		233600 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 217600 (1360%)

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 max amount of information (measured in MB per second) that can be transferred across the external memory interface in one second. It's worked out by multiplying the card's interface width by its memory speed. If it uses DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of Raster Operations Pipelines by the the card's clock speed. 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 many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
