A Closer Look at the GTX 550 Ti

According to NVIDIA’s the GF116 core is pin for pin compatible with the GF106 so we will likely see many board partners using reference GTS 450 cards as the basis for the new GTX 550 Ti line of products.

From all outside appearances, the reference GTX 550 Ti design features the same layout as the GTS 450 with a full length shroud and a centrally located 80mm intake fan.

The heatsink’s shroud has a slight indent as it moves closer to the fan in order to allow for some air movement space if two of these cards are placed in SLI. Also, the heatsink itself is the same basic aluminum fin / copper core affair which has proven itself quite successful on past NVIDIA cards.

Due to the low power requirements of the GTX 550 Ti, it maintains a single 6-pin power connector as well as a fairly standard 3+1 phase PWM. Meanwhile, it only has a single SLI connector so two of these cards can work in SLI.

Output connectors are in line with what we have come to expect from this generation of NVIDIA cards. A pair of DVI outputs and a single mini HDMI connector are included but we can expect most board partners to ship a mini HDMI to HDMI adaptor with their cards.

Other than the PCB colour, there really aren’t that many physical differences between the GTS 450 and GTX 550 PCBs (both are 8 ¼” long) but the memory layout has been fundamentally changed. Instead of using an 8 x 128MB layout (or 512MB per controller), the GTX 550 Ti is designed to accept mixed memory allotments so it uses four 128MB modules and two 256MB GDDR5 ICs. This also eliminates the need for mounting modules on the back of the PCB.
