is the first partner that has decided to change the cooler on the HD 5750 card. The card uses Arctic Cooling's cooler with 92mm fan, the same one that we had a chance to see on Powercolor's HD 4770 PCS card.
The PCS HD 5750 works at 700MHz for the core, has 720 stream processors, and comes with 1GB of GDDR5 memory clocked at 1150MHz (4.6Gbps) and paired up with a 128-bit memory interface. The different cooler might bring lower temperatures or less noise, but that's something that we still have to confirm.
In addition to the non-reference HD 5750 card, Powercolor has announced two HD 5770 cards as well. Both cards work at 850MHz for the core, 1200MHz (4.8Gbps) for 1GB of GDDR5 memory paired up with a 128-bit memory interface, and both feature 800 stream processors. The only difference is in the bundle, as the Battle Forge Edition comes with Battle Forge, (Who would have thought? sub.ed.) which is the only title that benefits from DirectX 11, at least for now.
The HD 5770 Battle Forge Edition is limited to EMEA region and its price is around US $10 higher. The current recommended prices for these cards are US $129 for the HD 5750 and US $159 for the HD 5770. You can find them listed here
