GeForce RTX 2080 SUPER vs Radeon RX Vega 64

Intro

Compare all of that to the Radeon RX Vega 64, which uses a 14 nm design. AMD has set the core frequency at 1247 MHz. The HBM2 memory runs at a frequency of 1890 MHz on this specific card. It features 4096 SPUs along with 256 Texture Address Units 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 small bit (about 1%) faster with regards to 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

If running with high levels of AA is important to you, then the GeForce RTX 2080 SUPER is the winner, by a large margin. (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 largest amount of information (in units of megabytes per second) that can be transferred across the external memory interface in a second. It is calculated by multiplying the bus width by the speed of its memory. If it uses DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the card's memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be processed in one second. This number is worked out by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in a second.

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