Radeon RX 5700 vs Radeon RX Vega 56

Intro

The Radeon RX 5700 makes use of a 7 nm design. AMD has clocked the core frequency at 1465 MHz. The GDDR6 RAM works at a speed of 14000 MHz on this card. It features 2304 SPUs along with 144 TAUs and 64 ROPs.

Compare all of that to the Radeon RX Vega 56, which features a core clock frequency of 1156 MHz and a HBM2 memory speed of 1600 MHz. It also features 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.

Memory Bandwidth: Memory bandwidth is the max amount of data (measured in megabytes per second) that can be moved past the external memory interface in a second. It's calculated by multiplying the interface width by the speed of its memory. If the card has DDR type memory, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with anti-aliasing, HDR and higher screen resolutions.

Texel Rate: Texel rate is the maximum texture map elements (texels) that can be applied in one second. This figure is worked out by multiplying the total amount of texture units of the card by the core 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 per second.

Pixel Rate: Pixel rate is the maximum amount of pixels the graphics card could possibly write to its local memory in a second - measured in millions of pixels per second. The figure is worked out by multiplying the number of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also called 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 - the lower the memory bandwidth is, the lower the ability to get to the maximum fill rate.
