Suomeksi550 Ti Cool Stream OC Edition
The back side of the PCB has barely any components. There are soldering points for six extra memory chips, but on the 1 GB version these are left unused. The cooler is held in place with four spring-loaded screws and there are no "warranty void"-stickers to prevent changing it for an aftermarket cooler.
Heatsink out of the way and we can also see the front side of the board. The only thing cooled here is the GF116 GPU, both the memory chips and the power supply components are left naked and are only cooled by the airflow. The GPU die is very small and there's a metal shim around it to prevent cracking the corners.
The card has total of six memory chips, which seems like an odd number for a card with one gigabyte of memory. All the memory chips are made by Hynix, but they vary in size and there are four 128 MB and two 256 MB chips.
Cooling
The cooler design is almost identical with the Intel boxed coolers, there's an aluminum heatsink with a copper die and an axial fan that pushes air through the heatsink. The heatsink is very slim, but should be enough to keep a card like the GTX 550 cool and the fan is made by Coolermaster and rated at 12 V 0,6 A (7,2 W).
Compared
The direct AMD-competitor for the GTX 550 Ti is the HD5770, and in side-by side comparison the cards are also exactly the same length. The Gainward GTX 560 Phantom uses a special PCB that is significantly shorter than the reference design and on the far right the HD6850 is clearly longer than any of the three others.
