GeForce RTX 2070 Super vs Radeon RX Vega 64

Intro

Compare that to the Radeon RX Vega 64, which features core clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs along with 256 TAUs and 64 ROPs.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

GeForce RTX 2070 Super		215 Watts
Radeon RX Vega 64		295 Watts
	Difference: 80 Watts (37%)

Memory Bandwidth

In theory, the Radeon RX Vega 64 is 8% quicker than the GeForce RTX 2070 Super overall, due to its greater bandwidth. (explain)

Radeon RX Vega 64		495411 MB/sec
GeForce RTX 2070 Super		458752 MB/sec
	Difference: 36659 (8%)

Texel Rate

The Radeon RX Vega 64 should be much (approximately 24%) better at AF than the GeForce RTX 2070 Super. (explain)

Radeon RX Vega 64		319232 Mtexels/sec
GeForce RTX 2070 Super		256800 Mtexels/sec
	Difference: 62432 (24%)

Pixel Rate

If running with high levels of AA is important to you, then the GeForce RTX 2070 Super is a better choice, by a large margin. (explain)

GeForce RTX 2070 Super		102720 Mpixels/sec
Radeon RX Vega 64		79808 Mpixels/sec
	Difference: 22912 (29%)

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 max amount of data (measured in MB per second) that can be moved past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR RAM, the result should be multiplied by 2 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, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum amount of texture map elements (texels) that can be applied in one second. This is worked out by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher this number, the better the video 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 number of pixels the video card could possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of Render Output Units 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 fill rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
