Radeon RX 580 vs Radeon RX Vega 64

Intro

The Radeon RX 580 makes use of a 14 nm design. AMD has clocked the core speed at 1257 MHz. The GDDR5 memory works at a speed of 2000 MHz on this specific model. It features 2304 SPUs as well as 144 TAUs and 32 ROPs.

Compare those specifications to the Radeon RX Vega 64, which makes use of a 14 nm design. AMD has clocked the core frequency at 1247 MHz. The HBM2 memory works at a speed of 1890 MHz on this specific card. It features 4096 SPUs as well as 256 Texture Address Units and 64 Rasterization Operator Units.

Memory Bandwidth: Memory bandwidth is the max amount of information (counted in MB per second) that can be moved past the external memory interface in one second. It is worked out by multiplying the card's interface width by its memory speed. If the card has DDR RAM, it should be multiplied by 2 again. If DDR5, multiply by ANOTHER 2x. The better the 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 can be processed in one second. This 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 applied in a second.

Pixel Rate: Pixel rate is the most pixels the video card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is worked out by multiplying the amount of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes 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 of the card - the lower the bandwidth is, the lower the ability to get to the max fill rate.
