GeForce RTX 2080 vs Radeon RX Vega 64

Intro

The GeForce RTX 2080 makes use of a 12 nm design. nVidia has set the core frequency at 1515 MHz. The GDDR6 RAM runs at a frequency of 14 MHz on this particular model. It features 2944 SPUs as well as 184 TAUs and 64 ROPs.

Compare those specifications to the Radeon RX Vega 64, which has a core clock frequency of 1247 MHz and a HBM2 memory frequency of 1890 MHz. It also makes use of a 2048-bit bus, and uses a 14 nm design. It features 4096 SPUs, 256 TAUs, and 64 Raster Operation Units.

GeForce RTX 2080 215 Watts
Radeon RX Vega 64 295 Watts
Difference: 80 Watts (37%)

Memory Bandwidth

Theoretically speaking, the Radeon RX Vega 64 is 8% faster than the GeForce RTX 2080 in general, due to its greater data rate. (explain)

Radeon RX Vega 64 495411 MB/sec
GeForce RTX 2080 458752 MB/sec
Difference: 36659 (8%)

Texel Rate

The Radeon RX Vega 64 should be a little bit (approximately 15%) more effective at anisotropic filtering than the GeForce RTX 2080. (explain)

Radeon RX Vega 64 319232 Mtexels/sec
GeForce RTX 2080 278760 Mtexels/sec
Difference: 40472 (15%)

Pixel Rate

The GeForce RTX 2080 will be quite a bit (about 21%) better at AA than the Radeon RX Vega 64, and capable of handling higher resolutions more effectively. (explain)

GeForce RTX 2080 96960 Mpixels/sec
Radeon RX Vega 64 79808 Mpixels/sec
Difference: 17152 (21%)

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.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved past the external memory interface in one second. The number is calculated by multiplying the card's interface width by its memory speed. If it uses DDR type memory, it must be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The higher the memory bandwidth, the better 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 number of texture map elements (texels) that can be processed per second. This 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 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 chip can possibly write to the local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of colour ROPs by the the card's clock speed. 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 output rate is also dependant on many other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
