GeForce RTX 2080 SUPER vs Radeon R9 280X

Intro

Compare that to the Radeon R9 280X, which comes with a GPU core clock speed of 850 MHz, and 3072 MB of GDDR5 memory running at 1500 MHz through a 384-bit bus. It also features 2048 Stream Processors, 128 Texture Address Units, and 32 Raster Operation 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 280X in general. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon R9 280X		288000 MB/sec
	Difference: 219904 (76%)

Texel Rate

The GeForce RTX 2080 SUPER is quite a bit (about 191%) faster with regards to AF than the Radeon R9 280X. (explain)

GeForce RTX 2080 SUPER		316800 Mtexels/sec
Radeon R9 280X		108800 Mtexels/sec
	Difference: 208000 (191%)

Pixel Rate

The GeForce RTX 2080 SUPER will be a lot (approximately 288%) faster with regards to AA than the Radeon R9 280X, and also capable of handling higher resolutions better. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon R9 280X		27200 Mpixels/sec
	Difference: 78400 (288%)

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: Memory bandwidth is the max amount of information (counted in megabytes per second) that can be transferred past the external memory interface within a second. It is worked out by multiplying the bus width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The better 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 amount of texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total number of texture units of the card by the core speed of the chip. The higher this number, the better the card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the most pixels the video card could possibly record to its local memory per second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core clock speed. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
