Radeon RX 5700 XT vs Radeon RX Vega 56

Intro

The Radeon RX 5700 XT comes with a core clock speed of 1605 MHz and a GDDR6 memory frequency of 14000 MHz. It also makes use of a 256-bit memory bus, and makes use of a 7 nm design. It is comprised of 2560 SPUs, 160 Texture Address Units, and 64 ROPs.

Compare those specifications to the Radeon RX Vega 56, which comes with a clock speed of 1156 MHz and a HBM2 memory speed of 1600 MHz. It also uses a 2048-bit bus, and uses a 14 nm design. It is comprised of 3584 SPUs, 224 Texture Address Units, 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

Theoretically speaking, the Radeon RX 5700 XT will be 9% quicker than the Radeon RX Vega 56 in general, due to its greater data rate. (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 bit (about 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

The Radeon RX 5700 XT is quite a bit (more or less 39%) faster with regards to FSAA than the Radeon RX Vega 56, and should be able to handle higher resolutions without slowing down too much. (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: Memory bandwidth is the largest amount of data (counted in MB per second) that can be transported past the external memory interface within a second. The number is calculated by multiplying the card's interface width by its memory clock speed. In the case of DDR type RAM, the result should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the memory bandwidth, the faster the card will be in general. It especially helps with anti-aliasing, HDR and high resolutions.

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

Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly write to its local memory in a second - measured in millions of pixels per second. The figure is calculated by multiplying the amount of ROPs by the the core speed of the card. ROPs (Raster Operations Pipelines - sometimes also referred to as 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, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the maximum fill rate.
