Closer Look: Sapphire HD 5550 OC 

At first glace of the Sapphire Radeon HD 5550 OC, you are going to notice a card that looks run-of-the-mill, you are going to get a heatsink/fan setup that is colored black that covers just the GPU and memory chips that are installed on the card. The PCB of the HD 5550 OC is a bright blue color just like its big brother, the HD5670. The card connects to your motherboard using a PCI-E 2.1 connection that is going to give the card all of the power that it is going to need to power it. The card does come with some nice connection features such as being able to connect to a monitor or display device using either the onboard DVI, HDMI, or DisplayPort connectors that are on the PCI bracket. You also can see that the card is very basic as far as other features such as no CrossFireX connectors at the top of the card, no extra power adapter located at the back, and no large heatsink that covers the entire card to give it a massive cooler.




















When you strip the cooler off of the card, you are going to be left with a bare blue PCB board that has a GPU located toward the middle of the card, you are also going to see four Samsung K4G10325FE HC05 memory chips positioned around the GPU that come clocked in at 1000MHz with a 128 bit Bus, giving you a memory bandwidth of 64.0GB/s. The Redwood core on the HD 5670 Ultimate is clocked all the way up to 650 MHz and is built on the 40nm technology for lower power consumption.



The heatsink/fan setup that comes installed on the Sapphire Radeon HD 5550 OC is very simplistic and reminds me of the old AMD stock heatsink/fans for their older XP chips. You get a nice large base that rests atop of the GPU but it does sit just above the memory chips located around the GPU to allow for a little extra cooling to them. The decent sized fan atop the heatsink is going to help blow all the heat generated by the card off into the chassis and on out into the room using the case fans.



Now we know exactly how both the cards are designed and how all of it is put together, it's time to take a look at the specifications for both of them.
