To cap things off here, we have a size comparison with the bigger and badder HD5850. The main difference on the front-side of the card is obvious. The HD5850 is considerably longer and the fan is a bit larger. One of the other differences is the fact that the HD5850 needs two 6-pin power-connectors instead of just one. That however is easily explained by the fact that the Cypress core, which is used in the HD5850 is a lot larger than the Juniper.
Here we have the same comparison of the cards from the back-side. Unlike the HD5770, the HD5850 has managed to squeeze in all of the memory chips onto the front-side of the PCB. The smaller size of the PCB just hasn't made it possible to do so with the HD5770.
One other clear difference can be spotted here also. If you look at the brackets, which are right behind the cores, the size-difference of the cores is clearly visible.
The cooler has also been screwed on with more screws, which is due to the fact that it weighs somewhat more.
Disassembled
Removing the cooler from the HD5770 was pretty much a walk in the park. Basically you just unscrew the four screws which are situated around the core-area, and the cooler should just come off. While this ease of installation may sound good, I'm a tad worried about the stresses the cooler-mounting may cause on the PCB as it is only held on by four screws. This should however be no issue, as the cards have a two-piece cooler, where the second piece covers the memory chips and supports the card itself.
Now here we have a closeup of the Juniper core.
Due to the fact that the engravings on the memory chips are so shallow, getting a decent picture with this schedule proved too much this
time. 
The code actually spells h5gq1h24afr, which in turn tell us that this chip is a GDDR5 chip, which runs specified at 1.5 V, which
should run at 2.5 Ghz.
