Colorful, the brains behind the iGame series of fully-loaded performance-thru-mainstream graphics cards is continuing to let its creativity fly. This time around, the company is working on a new GeForce GTS 450 graphics card that's "slim" in more ways than one. To begin with, the card will feature a single-slot cooling solution, next, the designers completely did away with "big" and redundant components on the PCB, and replaced them with higher-grade yet compact and less in number components. For example, while most other graphics card vendors fill up the 128-bit wide GDDR5 memory bus of the GeForce GTS 450 with eight 1 Gbit (128 MB) chips, with two chips sharing a 32-bit wide path, Colorful used just four higher-density memory chips. That's four 2 Gbit (256 MB) memory chips made by Hynix to achieve the same capacity, reducing board footprint, and possibly heat and energy draw.
All cylindrical capacitors are replaced by server-grade flatbed high-C POSCAP capacitors. The card uses a simple 3+1 phase VRM, driven by an ON-Semi made controller. The chokes used don't exactly sit on the PCB, rather, they're suspended in openings of the PCB, by their leads, this improves ventilation around the chokes, and reduces the size of the chokes on the obverse side, reducing the obstruction caused to the cooler. The PCB itself is well "ventilated". All free-space on the PCB is used to carve out vents for the cooler to draw in air from. Colorful did not mention when tentatively it plans to release this product.
