Radeon RX 5700 XT vs Radeon RX Vega 56

Intro

The Radeon RX 5700 XT features core clock speeds of 1605 MHz on the GPU, and 14000 MHz on the 8096 MB of GDDR6 memory. It features 2560 SPUs as well as 160 Texture Address Units and 64 Rasterization Operator Units.

Compare all of that to the Radeon RX Vega 56, which makes use of a 14 nm design. AMD has clocked the core speed at 1156 MHz. The HBM2 memory is set to run at a speed of 1600 MHz on this particular card. It features 3584 SPUs along with 224 TAUs and 64 ROPs.

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

Theoretically, the Radeon RX 5700 XT should be just a 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 should be a little bit (approximately 1%) more effective 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

If using lots of anti-aliasing is important to you, then the Radeon RX 5700 XT is the winner, by a large margin. (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.

Memory Bandwidth: Bandwidth is the max amount of data (counted in megabytes per second) that can be transported across the external memory interface in one second. The number is worked out by multiplying the card's bus width by the speed of its memory. In the case of DDR RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, 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 number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core speed of the chip. The better this number, the better the video card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in one second.

Pixel Rate: Pixel rate is the maximum number of pixels that the graphics card could possibly record to the local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel output rate is also dependant on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the max fill rate.
