Radeon RX 470 vs Radeon RX Vega 64

Intro

The Radeon RX 470 has a clock speed of 926 MHz and a GDDR5 memory speed of 1650 MHz. It also uses a 256-bit bus, and uses a 14 nm design. It is made up of 2048 SPUs, 128 TAUs, and 32 ROPs.

Compare all that to the Radeon RX Vega 64, which features a clock frequency of 1247 MHz and a HBM2 memory speed of 1890 MHz. It also features a 2048-bit bus, and makes use of a 14 nm design. It is made up of 4096 SPUs, 256 TAUs, and 64 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (in units of megabytes per second) that can be moved across the external memory interface in one second. The number is calculated by multiplying the interface width by its memory speed. If the card has DDR RAM, the result should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The higher the card's memory bandwidth, the better 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 texture map elements (texels) that are processed per 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 higher 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 a second.

Pixel Rate: Pixel rate is the most pixels that the graphics card can possibly write to the local memory per second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount 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 fill rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the potential to get to the maximum fill rate.
