Radeon RX 5600 XT vs Radeon RX Vega 56

Intro

Compare those specs to the Radeon RX Vega 56, which features a clock speed of 1156 MHz and a HBM2 memory frequency of 1600 MHz. It also makes use of a 2048-bit memory bus, and makes use of a 14 nm design. It is comprised of 3584 SPUs, 224 TAUs, and 64 ROPs.

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

Theoretically, the Radeon RX Vega 56 should perform quite a bit faster than the Radeon RX 5600 XT overall. (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 should be quite a bit (approximately 31%) faster with regards to anisotropic filtering 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 a high screen resolution is important to you, then the Radeon RX 5600 XT is superior to the Radeon RX Vega 56, not by a very large margin though. (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 max amount of data (measured in MB per second) that can be moved across the external memory interface in one second. It is calculated by multiplying the interface width by the speed of its memory. In the case of DDR memory, the result should be multiplied by 2 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 high resolutions.

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

Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate also depends on many other factors, most notably the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the maximum fill rate.
