Radeon HD 6570 (OEM) 2GB vs Radeon RX 550

Intro

The Radeon HD 6570 (OEM) 2GB uses a 40 nm design. AMD has set the core frequency at 650 MHz. The GDDR5 RAM is set to run at a speed of 1000 MHz on this specific card. It features 480 SPUs along with 24 TAUs and 8 Rasterization Operator Units.

Compare that to the Radeon RX 550, which has a core clock frequency of 1100 MHz and a GDDR5 memory speed of 1750 MHz. It also features a 128-bit memory bus, and uses a 14 nm design. It is comprised of 512 SPUs, 32 Texture Address Units, and 16 Raster Operation Units.

Memory Bandwidth: Memory bandwidth is the maximum amount of information (in units of megabytes per second) that can be transported across the external memory interface in a second. It's calculated by multiplying the card's bus width by its memory speed. If the card has DDR memory, it should be multiplied by 2 again. If 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, HDR and high resolutions.

Texel Rate: Texel rate is the maximum number of texture map elements (texels) that can be processed per second. This is calculated by multiplying the total texture units of the card by the core speed of the chip. The better 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 video card can possibly write to the local memory in one second - measured in millions of pixels per second. The figure is calculated by multiplying the number of colour ROPs by the the core clock speed. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel fill rate also depends on lots of other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to get to the max fill rate.
