Radeon HD 6570 (OEM) 2GB vs Radeon R7 250
Intro
The Radeon HD 6570 (OEM) 2GB has a GPU clock speed of 650 MHz, and the 1024 MB of GDDR5 RAM is set to run at 1000 MHz through a 128-bit bus. It also is comprised of 480 SPUs, 24 TAUs, and 8 ROPs.Compare that to the Radeon R7 250, which has a clock frequency of 1000 MHz and a GDDR5 memory speed of 1150 MHz. It also features a 128-bit bus, and uses a 28 nm design. It features 384 SPUs, 24 Texture Address Units, and 8 ROPs.

Memory Bandwidth: Memory bandwidth is the maximum amount of data (in units of megabytes per second) that can be moved over the external memory interface within a second. It is worked out by multiplying the card's bus width by the speed of its memory. If the card has DDR RAM, it must be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better 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 number of texture map elements (texels) that are processed in one second. This number is calculated by multiplying the total number of texture units by the core speed of the chip. The higher this number, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied in one second.
Pixel Rate: Pixel rate is the most pixels the video card could possibly write to its local memory in one second - measured in millions of pixels per second. Pixel rate is worked out by multiplying the amount of Raster Operations Pipelines 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 output rate also depends on many other factors, especially the memory bandwidth - the lower the bandwidth is, the lower the ability to reach the maximum fill rate.
