Photos of a non-reference Radeon HD 4850 graphics card with 2GB GDDR3 memory were published by Expreview. That's four times as much memory as a regular Radeon HD 4850 and massive overkill.
Actually Powercolor still uses AMD’s reference PCB, (you can see AMD name after the FCC mark), but based on the PCB they make lots of changes. It uses ZeroTherm full cooper GPU cooler with CVVT technology(Continue Variable Velocity Timing, just another Korean innovation), changed DRAM module to high capacity chips (detail still known). The card runs slightly higher than reference one, clocks at 665/2000MHz(core/memory)
