Radeon RX 5700 XT vs Radeon RX Vega 56

Intro

Compare those specifications to the Radeon RX Vega 56, which comes with core speeds of 1156 MHz on the GPU, and 1600 MHz on the 8192 MB of HBM2 memory. It features 3584 SPUs along with 224 Texture Address Units and 64 Rasterization Operator 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

Performance-wise, the Radeon RX 5700 XT should in theory be a little 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 (about 1%) better at AF 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 is much (more or less 39%) faster with regards to anti-aliasing than the Radeon RX Vega 56, and also will be capable of handling higher resolutions while still performing well. (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: Bandwidth is the max amount of data (measured in megabytes per second) that can be moved over the external memory interface in one second. It is calculated by multiplying the card's interface width by its memory clock speed. If the card has DDR type memory, it must be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the bandwidth is, the faster 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 worked out by multiplying the total texture units by the core clock speed of the chip. The better this number, the better the 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 most pixels that the graphics card could possibly record to its local memory in one second - measured in millions of pixels per second. The figure is worked out by multiplying the number of colour ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel fill rate is also dependant 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 maximum fill rate.
