Radeon HD 5570 vs Radeon HD 7750
Intro
The Radeon HD 5570 uses a 40 nm design. AMD has set the core speed at 650 MHz. The DDR3 memory works at a frequency of 900 MHz on this model. It features 400(80x5) SPUs along with 20 TAUs and 8 Rasterization Operator Units.Compare those specifications to the Radeon HD 7750, which comes with a core clock speed of 800 MHz and a GDDR5 memory frequency of 1125 MHz. It also uses a 128-bit bus, and makes use of a 28 nm design. It features 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Bandwidth is the maximum amount of information (counted in megabytes per second) that can be transferred across the external memory interface in one second. It's calculated by multiplying the interface width by its memory speed. If it uses DDR RAM, it must be multiplied by 2 once again. If DDR5, multiply by 4 instead. The higher the bandwidth is, 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 processed per second. This is worked out by multiplying the total amount of texture units of the card by the core speed of the chip. The better the texel rate, the better the graphics card will be at handling texture filtering (anisotropic filtering - AF). It is measured in millions of texels applied per second.
Pixel Rate: Pixel rate is the maximum amount of pixels the video card can possibly record to the local memory per second - measured in millions of pixels per second. Pixel rate is calculated by multiplying the amount of colour ROPs 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 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 reach the max fill rate.

Comments
One Response to “Radeon HD 5570 vs Radeon HD 7750”Plenty of ATI Radeon HD 7750 1GB graphics cards are just ancient DDR3.
Buyer beware, many versions released.
Powercolor has (10) versions listed.
(6) with GDDR5 and (4) with DDR3.
Just some of them:
Low Profile (4)DP - 2GB GDDR5
Full DVI/HDMI/DP -1GB GDDR5
Full DVI/HDMI/VGA -2GB DDR3
Full DVI/HDMI/VGA -1GB DDR3
DDR3 - memory clocked 800
GDDR5 - memory clocked 1125
Each DDR3 card is either "UEFI READY" or is not, leading to the four.
That is just Powercolor alone!
