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

Memory Bandwidth: Memory bandwidth is the largest amount of information (measured in MB per second) that can be transported over the external memory interface in a second. The number is calculated by multiplying the bus width by its memory clock speed. In the case of DDR type 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 amount of texture map elements (texels) that are applied in one second. This number is calculated by multiplying the total amount 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 amount of pixels that the graphics card can possibly record to its local memory in a second - measured in millions of pixels per second. The number is calculated by multiplying the number of ROPs by the clock speed of the card. ROPs (Raster Operations Pipelines - also sometimes called Render Output Units) are responsible for drawing the pixels (image) on the screen. The actual pixel rate also depends on quite a few other factors, especially the memory bandwidth - the lower the memory bandwidth is, the lower the ability to get to 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!
