GeForce RTX 2080 Ti vs Radeon R9 M380

Intro

Compare all that to the Radeon R9 M380, which has core clock speeds of 1000 MHz on the GPU, and 1500 MHz on the 4096 MB of GDDR5 memory. It features 640 SPUs along with 40 TAUs and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

Theoretically, the GeForce RTX 2080 Ti should perform quite a bit faster than the Radeon R9 M380 in general. (explain)

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

Texel Rate

The GeForce RTX 2080 Ti should be quite a bit (about 818%) better at texture 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

If running with a high screen resolution is important to you, then the GeForce RTX 2080 Ti is the winner, by far. (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 maximum amount of information (counted in MB per second) that can be moved past the external memory interface within a second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR type memory, it should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the memory bandwidth, 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 processed in one second. This number is calculated by multiplying the total amount of texture units by the core speed of the chip. The higher the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

Pixel Rate: Pixel rate is the maximum number of pixels the video card could possibly write to the local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate also depends on quite a few other factors, most notably the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to get to the max fill rate.
