Radeon RX 5600 XT vs Radeon RX Vega 56

Intro

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

Power Usage and Theoretical Benchmarks

Power Consumption (Max TDP)

Radeon RX 5600 XT		160 Watts
Radeon RX Vega 56		210 Watts
	Difference: 50 Watts (31%)

Memory Bandwidth

In theory, the Radeon RX Vega 56 should perform much faster than the Radeon RX 5600 XT in general. (explain)

Radeon RX Vega 56		419430 MB/sec
Radeon RX 5600 XT		344064 MB/sec
	Difference: 75366 (22%)

Texel Rate

The Radeon RX Vega 56 is much (more or less 31%) faster with regards to AF than the Radeon RX 5600 XT. (explain)

Radeon RX Vega 56		258944 Mtexels/sec
Radeon RX 5600 XT		198000 Mtexels/sec
	Difference: 60944 (31%)

Pixel Rate

If running with lots of anti-aliasing is important to you, then the Radeon RX 5600 XT is the winner, but it probably won't make a huge difference. (explain)

Radeon RX 5600 XT		88000 Mpixels/sec
Radeon RX Vega 56		73984 Mpixels/sec
	Difference: 14016 (19%)

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 maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. It's worked out by multiplying the bus width by its memory speed. If the card has DDR type RAM, it should be multiplied by 2 once again. If DDR5, multiply by 4 instead. The better the memory bandwidth, the better the card will be in general. It especially helps with AA, HDR and higher screen resolutions.

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

Pixel Rate: Pixel rate is the most pixels the graphics card could possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the clock 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 quite a few other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the ability to reach the max fill rate.
