Radeon HD 6570 (OEM) 2GB vs Radeon R7 250
Intro
The Radeon HD 6570 (OEM) 2GB uses a 40 nm design. AMD has clocked the core speed at 650 MHz. The GDDR5 RAM works at a frequency of 1000 MHz on this model. It features 480 SPUs as well as 24 TAUs and 8 ROPs.Compare all that to the Radeon R7 250, which comes with GPU core speed of 1000 MHz, and 1024 MB of GDDR5 memory running at 1150 MHz through a 128-bit bus. It also is made up of 384 Stream Processors, 24 TAUs, and 8 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (measured in megabytes per second) that can be moved across the external memory interface within a second. The number is calculated by multiplying the card's bus width by the speed of its memory. If the card has DDR memory, it must be multiplied by 2 again. If DDR5, multiply by 4 instead. The higher the bandwidth is, the faster 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 amount of texture map elements (texels) that can be processed in one second. This is calculated by multiplying the total amount of texture units of the card by the core clock speed of the chip. The better the texel rate, the better the video card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels processed in a second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to its local memory per 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 clock speed. ROPs (Raster Operations Pipelines - aka Render Output Units) are responsible for filling the screen with pixels (the image). The actual pixel rate also depends on lots of other factors, especially the memory bandwidth of the card - the lower the bandwidth is, the lower the potential to reach the max fill rate.
