GeForce RTX 2080 SUPER vs Radeon RX Vega 64

Intro

Compare those specifications to the Radeon RX Vega 64, which features a GPU core clock speed of 1247 MHz, and 8192 MB of HBM2 memory running at 1890 MHz through a 2048-bit bus. It also features 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

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

Texel Rate

The Radeon RX Vega 64 is just a bit (more or less 1%) faster with regards to AF 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

If using a high screen resolution is important to you, then the GeForce RTX 2080 SUPER is the winner, by far. (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: Memory bandwidth is the max amount of data (measured in MB per second) that can be moved across the external memory interface within a second. It is worked out by multiplying the card's interface width by its memory speed. In the case of DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics chip could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the number of ROPs by the clock speed of the card. 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, especially the memory bandwidth of the card - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
