GeForce RTX 2080 SUPER vs Radeon R9 280

Intro

Compare that to the Radeon R9 280, which uses a 28 nm design. AMD has set the core speed at 933 MHz. The GDDR5 memory runs at a speed of 1250 MHz on this particular model. It features 1792 SPUs as well as 112 TAUs and 32 Rasterization Operator Units.

Power Usage and Theoretical Benchmarks

Both cards have the same power consumption.

Memory Bandwidth

The GeForce RTX 2080 SUPER should in theory be quite a bit faster than the Radeon R9 280 in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon R9 280		240000 MB/sec
	Difference: 267904 (112%)

Texel Rate

The GeForce RTX 2080 SUPER should be a lot (approximately 203%) more effective at AF than the Radeon R9 280. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R9 280		104496 Mtexels/sec
	Difference: 212304 (203%)

Pixel Rate

The GeForce RTX 2080 SUPER should be quite a bit (more or less 254%) better at full screen anti-aliasing than the Radeon R9 280, and also capable of handling higher screen resolutions without losing too much performance. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R9 280		29856 Mpixels/sec
	Difference: 75744 (254%)

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 across the external memory interface in a second. It's calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, it should be multiplied by 2 once again. If it uses DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card can possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as 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 memory bandwidth is, the lower the potential to get to the maximum fill rate.
