Radeon RX 5700 XT vs Radeon RX Vega 56

Intro

Compare all of that to the Radeon RX Vega 56, which features GPU core speed of 1156 MHz, and 8192 MB of HBM2 RAM running at 1600 MHz through a 2048-bit bus. It also features 3584 SPUs, 224 TAUs, and 64 Raster Operation Units.

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

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

Memory Bandwidth

The Radeon RX 5700 XT should in theory perform a small bit faster than 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 will be just a bit (approximately 1%) faster with regards to 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

The Radeon RX 5700 XT should be a lot (about 39%) more effective at FSAA than the Radeon RX Vega 56, and capable of handling higher screen resolutions without losing too much performance. (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 data (measured in megabytes per second) that can be transported past the external memory interface in one second. The number is worked out by multiplying the card's bus width by its memory clock speed. If it uses DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the memory bandwidth, the faster the card will be in general. It especially helps with AA, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be applied per second. This number is calculated by multiplying the total amount of texture units 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the video card could possibly write to its local memory in a second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the number of colour ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
