The Sapphire HD 5570 comes with a low profile design and uses a single slot active cooling solution with auto fan control. The use of active cooling on the GPU core can reduce temperatures beyond that of a passively cooled heatsink, which can increase the overclocking potential of the graphics card. With a low power requirement of only 10 watts at idle and 43 watts at max load the graphics card does not need an extra power source other than the PCIe slot, and Sapphire states that a 400 watt power supply be enough to run this card. The HD 5570 comes with support for the new PCIe 2.1 standard, but is fully compatible with any PCIe x 16 slot. The graphics card also has support of CrossFireX which will allow you to run two graphics cards together for added performance in a supported motherboard. One other feature that adds to the value of graphics cards in this segment is the use of ATI's hybrid CrossFireX. This technology allows you Crossfire a low to mid range graphics card with an integrated graphics processor that is built into a motherboard chipset. The use of this technology can improve the gaming quality of your system, as well as increase the performance in daily computing tasks.
The HD 5570 comes with three display ports and, as you can see, is ideally setup for HTPC use. From right to left you have a DL-DVI-I port, Display port and a standard VGA port. The DL-DVI-I port is designed to provide high quality all digital video with supported resolutions up to 2560 x 1600. The Display port supports Eyefinity and can run up to three monitors at resolutions of 5670 x 1200, when using a single monitor it can the max resolution is 2560 x 1600. The VGA port is a very standard port for connecting graphics cards to display monitors, but unlike the DVI-I port the VGA can not support resolutions up to 2560 x 1600 and has a resolution that instead maxes out at 2048 x 1536. This is quite high, but if you have a 30" monitor with higher resolutions this would not be the best connection choice. To ensure compatibility with all HTPC cases, Sapphire has included two low profile bracket converters that will allow this card to be used in a low profile case.
The HD 5570 is built on the 40nm Redwood core with clock frequencies of 650MHz. It comes with 1GB of DDR3 memory rated at 1600MHz. The Redwood core also has 400 stream processors, a 128-bit interface, 16 ROPs and supports DX 11. There are a total of eight memory chips found on the HD 5570, with four being on the front of the card and the other four on the back side. The memory is manufactured my Samsung and has the model number K4W1G1646E-HC11 printed on them.
With a 128-bit interface and 400 stream processors it is going to be interesting to see how this card performs, but before we get to benchmarking, let's take a look at the included ATI software.
