Although it was Sapphire, which charmed visitors of its Computex booth with its single-slot, low-profile Radeon HD 7750 graphics card, PowerColor beat it to the punch by taking such a design to its logical conclusion, the market. PowerColor's HD 7750 LP is fully loaded, despite its puny size.
PowerColor designed a single-slot, low-profile cooling solution that consists of a copper plate, a dense aluminum channel array, and a 40-50 mm lateral flow fan that guides air through the channels, where heat dissipation takes place. The card relies on the PCI-Express slot for power, and uses a 2+1 phase VRM to condition it. High-grade CPL-made chokes, LFPAK MOSFETs, and conductive polymer capacitors, are used. Together, the VRM and cooler have the chops to keep the 1.5 billion transistor GPU ticking.
Despite limited VRM and cooling resources, the clock speeds of the PowerColor HD 7750 LP aren't lowered. The card sticks to AMD's older reference clock speeds of 800 MHz GPU, with 1125 MHz (4.50 GHz effective) memory (the newer revision ups core clock speed to 900 MHz for the HD 7750). It packs 1 GB of GDDR5 memory across a 128-bit wide memory interface. The Radeon HD 7750 is based on the 28 nm "Cape Verde" silicon, and is configured to have 512 Graphics CoreNext stream processors, and support for the entire AMD Southern Islands feature-set, including DirectX 11.1, HD3D, AMD APP, and next-generation Eyefinity. Display outputs of the PowerColor HD 7750 LP include one each of dual-link DVI-D, standard-size HDMI 1.4a (with 7.1 channel HD audio), and D-Sub (VGA). The D-Sub connector is detachable. PowerColor includes a low-profile bracket, which can be used to install the card in slim form-factor (SFF) chassis. PowerColor did not reveal the pricing of the HD 7750 LP, though we expect it to command a tiny premium over common HD 7750 cards in the market. Single-slot + low-profile could end up being a major selling point.
