When you first pull the PowerColor HD5770s out of their packaging, you are going to notice that there is a single slot cooler installed on the card that pretty much covers the entire card. There is a little bit of space at the front of the card that is not covered to allow for the warm air that is expelled from the cooler to flow out. The cooler does extend over the edge of the card (which is where the fan is placed) in order to intake fresh air from the rest of the case. This helps in delivering a constant supply of fresh air to the cooler. The PCB of the card is a bright red which goes well with the overall design of the card and cooler.
Like all of the higher end video cards out there, there is support for a multi-card setup. With the ATI (now AMD) side of things, you have CrossFireX. To enable CrossFireX, you need to install the CrossFire bridge on the card. This is done by connecting one end of the bridge to each of the cards via the connection at the top of each card. The connector is located right behind the slot bracket of each card. At the bottom of the card is the PCI-E connector where the card is going to be able to connect and communicate with the motherboard. The front of the card is where you are going to find all of the video out connections. The HD5770 has the ever popular DVI out but it is also equipped with DVI and DisplayPort adapters. The back end of the card under the cooler is where you will find the 6-pin PCI-E power adapter. Since the card requires more power than the PCI-E slot can deliver, additional power is needed from the power supply.
Once you get the cooler removed from the PCB of the PowerColor HD5770, you are going to see that there are four memory chips located around the GPU. There are also four more of them located on the back side of the card. The memory modules are manufactured by Hynix with the part number H5GQ1H24AFR-T2C. They are rated to operate at 5.0GB/s using a whopping 1.5 volts. The GPU that is installed on the PowerColor HD5770 is the Juniper chip 215-0754013. The HD5770 is going to support Microsoft DX11 and ShaderModel 5.0.
The cooler that is installed on the PowerColor HD5770 is unique in the fact that it is the first HD5770 with a single slot air cooling solution. The blower fan installed on the cooler is at the end of the cooler itself to help suck in fresh air from all around the card and push it though to help cool the heat sink. The base of the heat sink on the cooler is an all copper base that has direct contact with the GPU to give it maximum cooling performance.
Now that we know exactly how the card is setup, let's take a look at the specifications of the PowerColor HD5770.
