GeForce RTX 2080 SUPER vs Radeon RX Vega 64

Intro

Compare that to the Radeon RX Vega 64, which uses a 14 nm design. AMD has set the core frequency at 1247 MHz. The HBM2 RAM runs at a frequency of 1890 MHz on this specific model. It features 4096 SPUs along with 256 TAUs and 64 Rasterization Operator Units.

Radeon RX Vega 64		495411 MB/sec
	Difference: 12493 (3%)

Texel Rate

The Radeon RX Vega 64 should be a little bit (more or less 1%) better at anisotropic filtering than the GeForce RTX 2080 SUPER. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
GeForce RTX 2080 SUPER		316800 Mtexels/sec
	Difference: 2432 (1%)

Pixel Rate

The GeForce RTX 2080 SUPER will be much (about 32%) more effective at AA than the Radeon RX Vega 64, and also able to handle higher resolutions while still performing well. (explain)

GeForce RTX 2080 SUPER		105600 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 25792 (32%)

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 data (measured in megabytes per second) that can be transported across the external memory interface within a second. It's calculated by multiplying the bus width by its memory clock speed. If the card has DDR type RAM, it should be multiplied by 2 once 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, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels that the graphics card can possibly record to the local memory per second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of colour ROPs by the clock 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 output rate also depends on many other factors, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
