GeForce RTX 2080 SUPER vs Radeon R9 M380

Intro

Compare those specs to the Radeon R9 M380, which makes use of a 28 nm design. AMD has set the core speed at 1000 MHz. The GDDR5 RAM runs at a speed of 1500 MHz on this particular model. It features 640 SPUs as well as 40 Texture Address Units and 16 ROPs.

Power Usage and Theoretical Benchmarks

Memory Bandwidth

The GeForce RTX 2080 SUPER, in theory, should be a lot faster than the Radeon R9 M380 overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon R9 M380		96000 MB/sec
	Difference: 411904 (429%)

Texel Rate

The GeForce RTX 2080 SUPER should be much (more or less 692%) better at anisotropic filtering than the Radeon R9 M380. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R9 M380		40000 Mtexels/sec
	Difference: 276800 (692%)

Pixel Rate

The GeForce RTX 2080 SUPER will be quite a bit (approximately 560%) faster with regards to FSAA than the Radeon R9 M380, and will be able to handle higher screen resolutions more effectively. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R9 M380		16000 Mpixels/sec
	Difference: 89600 (560%)

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 moved past the external memory interface in one second. It is worked out by multiplying the bus width by the speed of its memory. If it uses DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with AA, High Dynamic Range and high resolutions.

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

Pixel Rate: Pixel rate is the most 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 number of ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on many other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
