Radeon HD 6570 (OEM) 2GB vs Radeon R7 250
Intro
The Radeon HD 6570 (OEM) 2GB has a GPU core 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 made up of 480 Stream Processors, 24 TAUs, and 8 ROPs.Compare that to the Radeon R7 250, which features a core clock speed of 1000 MHz and a GDDR5 memory frequency of 1150 MHz. It also makes use of a 128-bit bus, and makes use of a 28 nm design. It features 384 SPUs, 24 TAUs, and 8 ROPs.

Memory Bandwidth: Bandwidth is the max amount of information (in units of MB per second) that can be transported across the external memory interface in one second. It's worked out by multiplying the interface width by the speed of its memory. If the card has DDR type memory, it should be multiplied by 2 once again. If DDR5, multiply by ANOTHER 2x. The higher the 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 texture map elements (texels) that can be applied per second. This figure is calculated by multiplying the total number of texture units of the card by the core clock speed of the chip. The better this number, the better the graphics card will be at texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum number of pixels the graphics card can possibly write to its local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Raster Operations Pipelines by the the core speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for outputting the pixels (image) to the screen. The actual pixel fill rate is also dependant on lots of other factors, most notably the memory bandwidth - the lower the memory bandwidth is, the lower the ability to reach the max fill rate.
