Radeon RX 5700 XT vs Radeon RX Vega 56

Intro

The Radeon RX 5700 XT has a core clock frequency 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 features 2560 SPUs, 160 TAUs, and 64 ROPs.

Compare that to the Radeon RX Vega 56, which has clock 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.

Radeon RX Vega 56 419430 MB/sec
Difference: 39322 (9%)

Texel Rate

The Radeon RX Vega 56 will be just a bit (about 1%) more effective at texture filtering 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 should be quite a bit (more or less 39%) better at FSAA than the Radeon RX Vega 56, and also able to handle higher resolutions more effectively. (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 maximum amount of information (in units of MB per second) that can be transferred past the external memory interface in one second. The number is worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR memory, it must be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the card's 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 applied in one second. This number is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The higher the texel rate, the better the card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels in one second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to the local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the number of Render Output Units by the the core speed of the card. ROPs (Raster Operations Pipelines - also called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate also depends on quite a few other factors, most notably the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the maximum fill rate.
