Once you get the Sapphire HD5830 Xtreme out of its packaging, you are going to notice that there is a large full-coverage cooler on it. Directly in the center of the cooler is a large fan that is going to suck in fresh air from inside of your chassis and blow it directly down on the heat sink underneath. There is a greenish colored sticker at the back end of the card's cooler that proudly displays not only the AMD Radeon Graphics badge but the Radeon HD5830 model name. There are chrome accents all along the edges of the cooler to make it a little bit nicer to look at. When you flip the card over, you are going to see the bright blue PCB that the card is built on. There are four compression screws that are holding the cooler down tight to the card to give the best contact to the GPU as possible.
Looking at the rear I/O shield of the Sapphire HD5830 Xtreme, you are going to see that the card has a total of three different display adapters built in. You have a single DVI, a single HDMI, and a single DisplayPort adapter. Sitting right above the display adapters you are going to find a large slit in the shield that is going to allow the hot air from inside of the cooler to escape your chassis to help cool down the ambient air temperature inside. Hopefully, resulting in lower operating temperatures. On the oposite end of the card, you are going to see that there is an additional exhaust area to further help cool down the card, however this area exhausts into your chassis. At the top of the card towards the front of the card is where you are going to find a single CrossFireX bridge connector so you can connect a second HD5830 Xtreme card for increased performance. Still on the top of the card, you are going to find two 6 pin PCI-E power adapters to add additional power to the graphics card.
Once you get the cooling solution taken off of the Sapphire HD5830 Xtreme, you are going to see a very pretty naked graphics card. There are a total eight 128MB ram chips installed around the GPU core. There is a slim RAM sink installed on top of the voltage regulators towards the front of the graphics card to help keep them cool during operation, allowing for a more stable vCore. The cooler itself has a total of three copper heatpipes that travel from the copper base of the heat sink into the large fin array to help dissipate the heat generated by the graphics card. Two of the heat pipes travel towards the rear of the card while one goes towards the front.
Sapphire has the ATI Cypress GPU installed on the HD5830 Xtreme graphics card and is clocked in at 800MHz. There are also a total of 2154 Million transistors inside of the GPU core, a total of 16 ROPs, all on a 334mm2 die built on the 40nm technology. Sapphire decided to install a total of 1024MB of GDDR5 memory on the HD5830 Xtreme, these memory modules are manufactured by Elpida with the model number of W1032BABG. When you do a simple search on Elpida's website, you are able to find out that they are rated to run at 1.5V, give you a refresh cycle of 8K/32ms, and come lead and halogen free.
Now that we know the layout of the Sapphire HD5830 Xtreme graphics card, we should take a close look at Sapphire's HD5850 Xtreme card.
