The Sapphire HD 5670 is built upon the 40nm Redwood core that comes with clock speeds of 775Mhz on the core and 1000MHz on the 1GB of GDDR5 memory running through a 128bit bus. There are a total of 6 different models of this card with varying specification with the biggest being the difference in the memory capacity and whether the card has Hyper Memory support. The cooler is made by Arctic cooling and is a two slot design. The Sapphire HD 5670 is meant to be used in a 16x PCIE 2.0 slot but can be used in a PCIe 1.0 16x slot as well with support for PCIe 2.1. The PCB is blue and by the standards of the 5 series is the runt of the bunch at just about 6.5 inches in length.
This card comes with a wealth of connectivity options that would make this card perfect for the HTPC builder with native DisplayPort, HDMI 1.3 that offers # Dolby® TrueHD and DTSHD Master AudioTM Support and a dual link DVI connection. With this setup you can run an Eyefinity setup at resolutions of up to 4800x900 60hz. The back side of the HD 5670 is barren and does not contain the power connection we are so used to seeing on higher end cards. This one just does not need it based on its power consumption of 61 watts under load and 14 watts at idle. With that said, a 400 watt power supply is recommended. For CrossfireX, which is available on this card with the dual bridge connections, it jumps to 500W.
Cooling is handled by way of the Artic Cooling heatsink and fan assembly that is reasonably quiet for its size. The heatsink block is all aluminum without a copper plate or core and should easily dissipate the 61watt heat load from this card. The TIM application is about par for the course and is easily removable.
The back of the card has a total of 4 of the 8 Hynix memory modules that are rated to run at 5000Mhz but are only clocked to 4000MHz. The 40nm Redwood core is rated to run at 775MHz with its 400 stream processors, 20 texture units and 32ROPs.
Lets get the card installed and setup so we can see what really under the hood.
