GeForce RTX 2080 vs Radeon RX 480 4GB

Intro

Compare all that to the Radeon RX 480 4GB, which uses a 14 nm design. AMD has set the core speed at 1120 MHz. The GDDR5 memory runs at a speed of 1750 MHz on this particular model. It features 2304 SPUs as well as 144 TAUs and 32 Rasterization Operator Units.

	Difference: 229376 (100%)

Texel Rate

The GeForce RTX 2080 is quite a bit (approximately 73%) more effective at texture filtering than the Radeon RX 480 4GB. (explain)

GeForce RTX 2080		278760 Mtexels/sec
Radeon RX 480 4GB		161280 Mtexels/sec
	Difference: 117480 (73%)

Pixel Rate

The GeForce RTX 2080 is much (about 171%) better at FSAA than the Radeon RX 480 4GB, and also will be capable of handling higher screen resolutions without slowing down too much. (explain)

GeForce RTX 2080		96960 Mpixels/sec
Radeon RX 480 4GB		35840 Mpixels/sec
	Difference: 61120 (171%)

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 max amount of data (counted in megabytes per second) that can be transported over the external memory interface in one second. The number is worked out by multiplying the bus width by its memory clock speed. If it uses DDR memory, the result should be multiplied by 2 again. If it uses 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, HDR and high resolutions.

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

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