GeForce RTX 2080 SUPER vs Radeon RX Vega 64

Intro

Compare those specs to the Radeon RX Vega 64, which makes use of a 14 nm design. AMD has clocked the core frequency at 1247 MHz. The HBM2 memory works at a speed of 1890 MHz on this particular model. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2080 SUPER		250 Watts
Radeon RX Vega 64		295 Watts
	Difference: 45 Watts (18%)

Memory Bandwidth

The GeForce RTX 2080 SUPER, in theory, should be just a bit faster than the Radeon RX Vega 64 overall. (explain)

GeForce RTX 2080 SUPER		507904 MB/sec
Radeon RX Vega 64		495411 MB/sec
	Difference: 12493 (3%)

Texel Rate

The Radeon RX Vega 64 will be a bit (about 1%) more effective at 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 lots of anti-aliasing is important to you, then the GeForce RTX 2080 SUPER is a better choice, and very much so. (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 largest amount of data (counted in megabytes per second) that can be moved across the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory speed. If it uses DDR memory, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The higher the 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 is calculated by multiplying the total texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly record to the local memory in one second - measured in millions of pixels per second. The number is calculated by multiplying the amount of Raster Operations Pipelines by the clock speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to reach the max fill rate.
