The Radeon HD 7850 Twin Frozr III OC is a special edition of the Radeon HD 7850. Running on the Pitcairn Pro architecture, the core clock Twin Frozr III is factory-overclocked, pushing the standard 860MHz up to 900MHz.
The heart of this card is AMD’s GCN (Graphics Core Next) technology. Based on 28nm manufacturing process, AMD fit an impressive 4.3 billion transistors into the single GPU. Equipped with 16 Compute Units, each with 64 Vector Units for 1024 Stream Processors, the HD7850 Twin Frozr III has the ability to push the limits of DirectX 11.1 gaming effects.
Overclocking
The “Twin Frozr III” refer to the unique heating pipe and fans, designed to keep things cool when the going gets hot. The special blade design is claimed to generate 20% more airflow than traditional designs, is 10℃ cooler and is 13.7dB quieter than standard designs.
When used with the MSI Afterburner overclocking software, the MSI HD7850 Twin Frozr 2GD5/OC supports GPU overvoltage function. But we noticed on a Tom’s Hardware forum discussion that it is possible to get a 1050 core clock and 1450 RAM clock without upping the voltage.
