Radeon RX 5700 vs Radeon RX Vega 64

Intro

The Radeon RX 5700 has a clock speed of 1465 MHz and a GDDR6 memory speed of 1750 MHz. It also features a 256-bit bus, and uses a 7 nm design. It is comprised of 2304 SPUs, 144 TAUs, and 64 ROPs.

Compare those specs to the Radeon RX Vega 64, which comes with core clock speeds of 1247 MHz on the GPU, and 1890 MHz on the 8192 MB of HBM2 RAM. It features 4096 SPUs as well as 256 Texture Address Units and 64 ROPs.

Memory Bandwidth: Memory bandwidth is the largest amount of information (in units of megabytes per second) that can be transported across the external memory interface within a second. It is calculated by multiplying the bus width by the speed of its memory. If the card has DDR RAM, it should be multiplied by 2 again. If it uses DDR5, multiply by 4 instead. The better the card's memory bandwidth, the better the card will be in general. It especially helps with anti-aliasing, High Dynamic Range and higher screen resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that are applied in one second. This figure is worked out by multiplying the total number of texture units by the core clock speed of the chip. The higher the texel rate, the better the 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 maximum amount of pixels that the graphics chip 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 ROPs by the the card's clock speed. ROPs (Raster Operations Pipelines - sometimes also referred to as Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel output rate is also dependant on quite a few other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the potential to get to the maximum fill rate.
