GeForce RTX 2080 vs Radeon R9 M380

Intro

Compare those specs to the Radeon R9 M380, which uses a 28 nm design. AMD has clocked the core frequency at 1000 MHz. The GDDR5 memory works at a frequency of 1500 MHz on this card. It features 640 SPUs along with 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce RTX 2080 should in theory perform a lot faster than the Radeon R9 M380 in general. (explain)

GeForce RTX 2080		458752 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 362752 (378%)

Texel Rate

The GeForce RTX 2080 will be much (more or less 597%) faster with regards to anisotropic filtering than the Radeon R9 M380. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 238760 (597%)

Pixel Rate

The GeForce RTX 2080 is quite a bit (approximately 506%) better at AA than the Radeon R9 M380, and also capable of handling higher screen resolutions while still performing well. (explain)

GeForce RTX 2080		96960 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 80960 (506%)

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 largest amount of information (counted in megabytes per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the card's bus width by its memory clock speed. In the case of DDR memory, the result should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the card's 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 are processed 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 graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly record to its local memory per second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Render Output Units by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
