Closer Look: Sapphire HD 5670 Ultimate
Taking a look at the Sapphire Radeon HD 5670 Ultimate, you are going to notice that there is no fan anywhere to be found on the card's cooling system, it is comprised completely of a heatsink. The large heatsink that covers almost the entire front of the card has two heatpipes that go from the heatsink base to the array of heatsink fins positioned above the card. The PCB of the card is a nice bright blue color that gives it unique look. There are no additional power adapters on the card, meaning that the power that it is going to get from the PCI-E 2.1 port is going to be enough to power the 40nm core and the rest of the card. When you take a look at the PCI bracket, you will see that you have three different ways to connect a display, you can use either the DVI, HDMI, or DisplayPort connections. The Sapphire HD5670 Ultimate also does support EyeFinity, meaning you can connect three displays to the card and play games with all three monitors being used.
As I mentioned above, the card does use the PCI-E 2.1 slot on your motherboard to not only grab all the power that it is going to need to run but also to transfer all of the data between the motherboard. The HD 5670 Ultimate also does have two CrossFireX connectors at the top of the card by the PCI bracket, these are going to be used to connect two cards together so that they can work together to produce the maximum peformance.
When you take the large heatsink off of the card, you are left with a naked blue HD 5670 Ultimate, you will see the four Samsung memory chips on the front (there are four more on the back) as well as the GPU itself. The Samsung K4G10325FE HC05 GDDR5 memory chips are clocked at 1000MHz, and with a bus width of 128bit, you are looking at a total of 60.0GB/s bandwidth. The Redwood core on the HD 5670 Ultimate is clocked all the way up to 775 MHz and is built on the 40nm technology for lower power consumption.
All of the heatpipes on the large sized heatsink that comes on the Sapphire HD 5670 Ultimate meet up at the copper base that is positioned atop of the GPU to help pull the heat off of it to keep the rest of the card cool, the heatpipes take the heat to above the card where there is a large array of fins to dissipate the heat off into the rest of the case by the case fans that are already blowing the air out of the case. Placed on top of the fins, there is a nice Sapphire logo so that you will always know who's card you have in your system, the heatpipes that go into the fin array are positioned with a little bit of a gap and are not directly parallel to each other to help the heat move to a different place in array.
Now that we know how the Sapphire Radeon HD 5670 Ultimate is designed, it's time to take a look at the HD 5550 OC then off to the specifications of each.
