GeForce RTX 2070 Super vs Radeon RX Vega 64

Intro

Compare those specifications to the Radeon RX Vega 64, which comes with a clock speed of 1247 MHz and a HBM2 memory frequency of 1890 MHz. It also features a 2048-bit bus, and makes use of a 14 nm design. It features 4096 SPUs, 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

The Radeon RX Vega 64 should in theory be a bit faster than the GeForce RTX 2070 Super overall. (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 (more or less 24%) better at anisotropic filtering 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 using lots of anti-aliasing is important to you, then the GeForce RTX 2070 Super is superior to the Radeon RX Vega 64, by far. (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 information (counted in MB per second) that can be transported across the external memory interface in a second. It is calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, the result should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. 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 high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This number is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card can 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 ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the max fill rate.
