The ASUS EAH5770 packs new CUcore technology, integrating a distinct copper rod weighing up to 5.8oz within the fan assembly to better absorb and disperse heat.
For extreme players, the ASUS-designed EAH5870, EAH5850, EAH5830 graphics cards also deploy exclusive Voltage Tweak, which allows users to modify GPU voltage via the SmartDoctor application for up to a 50% performance gain.
However, for those craving both performance and thermal efficiency, at the top of the range lies the ASUS EAH5850 DirectCU TOP/2DIS/1GD5, providing users with the efficient cooling and overclocking.
The ASUS EAH5850 DirectCU TOP/2DIS/1GD5 and EAH5830 DirectCU/2DIS/1GD5 are equipped with the DirectCU technology, featuring two 8mm, flattened copper heat pipes that come into contact with the GPU directly. This allows for up to 20% better heat dissipation during gameplay compared to reference design models. With DirectCU technology, the ASUS EAH5850 DirectCU TOP is capable of 35% quieter performance compared to reference.
The ASUS EAH5770 CUcore/2DIS/1GD5 features yet another cooling design using copper for better heat dissipation. CUcore technology consists of a specially-designed fan integrating a tuning-fork shaped heatsink, increasing the heat dissipation surface area by as much as 22%. A copper rod weighing up to 5.8oz is embedded in the fan assembly to disperse heat as fast as possible. Similar to the ASUS EAH5850 DirectCU TOP, the ASUS EAH5770 CUcore/2DIS/1GD5 is also quieter?by approximately 15dB?compared to generic fans, providing maximum cooling with less noise.
The ASUS EAH5870 TOP and EAH5850 DirectCU TOP graphics cards come at default GPU speeds of 900MHz and 765MHz, and memory clock speeds of 4900MHz and 4600MHz, respectively. EAH5850 DirectCU TOP has been specially singled out from the rest of the series due to the overclock potential of the GPUs to reach speeds of 800MHz. Additionally, Voltage Tweak technology provides users with the option of boosting GPU voltages for up to a further 29% increase in performance. These extreme upgrades propel the ASUS EAH5000 TOP Series to the forefront of graphics cards technology, with a 3DMark Vantage Extreme Preset score of up to 9,252?a decisive 50% improvement compared to reference boards.
The ASUS EAH5000 Series features a suite of design features. The exclusive Dust-proof Fan adds enhanced endurance to the ASUS EAH5000 Series. Dust-proof Fans are double sealed to repel dust and extend the longevity of fan assemblies by up to 10,000 hours, 25% longer than regular fans found on generic graphics cards. The ASUS EAH5000 Series is also equipped with the GPU Guard. Originally used in military-grade products, GPU Guard doubles the structural integrity of the graphics card to prevent PCB cracks from occurring. The card further features fusing and EMI shielding, safeguarding both user and component. Having a fuse eliminates dangers posed by electrical overcurrents, a protection aided by the multiple sets of input fuses on the circuit board, which activate to interrupt the flow of excessive electrical current. Thus, the risk of irreparable damage to the card is reduced. The EMI shield reduces up to 66% of EMI interference given off and received by the card, protecting users from potentially harmful EMI radiation while delivering stable signals for clearer, undisrupted images.
