GeForce RTX 2080 Ti vs Radeon R9 M380

Intro

Compare that to the Radeon R9 M380, which has a clock speed of 1000 MHz and a GDDR5 memory frequency of 1500 MHz. It also makes use of a 128-bit memory bus, and makes use of a 28 nm design. It is made up of 640 SPUs, 40 TAUs, and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

In theory, the GeForce RTX 2080 Ti is 557% faster than the Radeon R9 M380 overall, due to its higher data rate. (explain)

GeForce RTX 2080 Ti		630784 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 534784 (557%)

Texel Rate

The GeForce RTX 2080 Ti will be much (more or less 818%) better at anisotropic filtering than the Radeon R9 M380. (explain)

GeForce RTX 2080 Ti		367200 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 327200 (818%)

Pixel Rate

The GeForce RTX 2080 Ti is much (about 643%) better at FSAA than the Radeon R9 M380, and should be able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 2080 Ti		118800 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 102800 (643%)

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 data (measured in MB per second) that can be transported across the external memory interface within a second. It's worked out by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the better the card will be in general. It especially helps with AA, High Dynamic Range and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly record to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
