GeForce RTX 3080 12 GB vs Radeon R9 M380

Intro

Compare those specifications to the Radeon R9 M380, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 memory is set to run at a frequency of 1500 MHz on this particular model. It features 640 SPUs along with 40 Texture Address Units and 16 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce RTX 3080 12 GB, in theory, should be a lot faster than the Radeon R9 M380 overall. (explain)

GeForce RTX 3080 12 GB		934298 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 838298 (873%)

Texel Rate

The GeForce RTX 3080 12 GB will be much (about 782%) more effective at anisotropic filtering than the Radeon R9 M380. (explain)

GeForce RTX 3080 12 GB		352800 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 312800 (782%)

Pixel Rate

If running with a high screen resolution is important to you, then the GeForce RTX 3080 12 GB is a better choice, and very much so. (explain)

GeForce RTX 3080 12 GB		141120 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 125120 (782%)

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 (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. In the case of DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The better the bandwidth is, 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 number of texture map elements (texels) that are processed per second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the amount of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
