Radeon HD 5570 vs Radeon HD 7750
Intro
The Radeon HD 5570 comes with a clock frequency of 650 MHz and a DDR3 memory speed of 900 MHz. It also uses a 128-bit memory bus, and makes use of a 40 nm design. It is made up of 400(80x5) SPUs, 20 Texture Address Units, and 8 ROPs.Compare those specifications to the Radeon HD 7750, which comes with a GPU core clock speed of 800 MHz, and 1024 MB of GDDR5 memory set to run at 1125 MHz through a 128-bit bus. It also is comprised of 512 SPUs, 32 Texture Address Units, and 16 ROPs.

Memory Bandwidth: Memory bandwidth is the max amount of data (counted in MB per second) that can be moved over the external memory interface within a second. It's worked out by multiplying the card's interface width by its memory clock speed. In the case of DDR type memory, it should be multiplied by 2 again. If it uses DDR5, multiply by ANOTHER 2x. The better the bandwidth is, the faster the card will be in general. It especially helps with AA, HDR and higher screen resolutions.
Texel Rate: Texel rate is the maximum texture map elements (texels) that can be processed per second. This figure is worked out by multiplying the total texture units of the card by the core speed of the chip. The higher this number, the better the 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 could possibly record to the local memory in one second - measured in millions of pixels per second. The number is worked out by multiplying the amount of Render Output Units by the the card's clock speed. ROPs (Raster Operations Pipelines - aka 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 of the card - the lower the bandwidth is, the lower the ability to reach the maximum 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!
