PowerColor launched its second Radeon HD 7750 graphics card, a Go! Green variant. Models of this series tend to be energy-efficient (with slightly lowered voltages, reducing power draw), while maintaining reference clock speeds. Another striking feature of Go! Green variants is their silent passive-heatsink that cools the GPU and VRM. To maintain high temperature tolerance, and energy-efficiency, PowerColor tends to employ high-grade voltage regulation components on their Go! Green cards. In case of this card, it is said to utilize PowerPAK SO-8 MOSFETs, shielded chokes, and conductive-polymer capacitors.
The card sticks to reference clock speeds of 800 MHz (core) and 1125 MHz / 4.50 GHz effective (memory), packs 512 Graphics CoreNext stream processors, and 1 GB of GDDR5 memory over a 128-bit wide memory interface. The cooler is similar to the one featured on previous-generation Go! Green cards from PowerColor, it consists of a dense aluminum fin heatsink, to which heat is conveyed by copper heat pipes that draw head directly off the core. Heat dissipation happens passively. Expect the card to charge a tiny premium over other Radeon HD 7750 cards in the market.
