Radeon RX 5700 XT vs Radeon RX Vega 56

Intro

Compare that to the Radeon RX Vega 56, which comes with a GPU core clock speed of 1156 MHz, and 8192 MB of HBM2 memory running at 1600 MHz through a 2048-bit bus. It also is comprised of 3584 Stream Processors, 224 TAUs, and 64 ROPs.

Radeon RX Vega 56		210 Watts
Radeon RX 5700 XT		225 Watts
	Difference: 15 Watts (7%)

Memory Bandwidth

Performance-wise, the Radeon RX 5700 XT should theoretically be just a bit superior to the Radeon RX Vega 56 in general. (explain)

Radeon RX 5700 XT		458752 MB/sec
Radeon RX Vega 56		419430 MB/sec
	Difference: 39322 (9%)

Texel Rate

The Radeon RX Vega 56 should be just a bit (more or less 1%) more effective at texture filtering than the Radeon RX 5700 XT. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon RX 5700 XT		256800 Mtexels/sec
	Difference: 2144 (1%)

Pixel Rate

If running with high levels of AA is important to you, then the Radeon RX 5700 XT is the winner, by far. (explain)

Radeon RX 5700 XT		102720 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 28736 (39%)

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 (measured in megabytes per second) that can be transported past the external memory interface in a second. It is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the memory bandwidth, the better 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 number of texture map elements (texels) that can be processed in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels per second.

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