Not long ago, we had just exposed the ASUS non-public version of the HD 7970 graphics card for everyone, but that time there was only a very vague picture, and we had no idea about the specific specifications. Today, the more detailed specification of this video card was finally exposed, and the name was also confirmed, that is, the ASUS Radeon HD 7970 DirectCu II.
Although Asustek and Gigabyte have previously released non-public version of the HD 7970 graphics card, only the non-public version of the heatsink has been replaced. The PCB part is still a complete public version of the design. Relative to the above two, although the Asus Radeon HD 7970 DirectCu II was exposed later, it was a complete non-public version of the graphics card. The PCB layout was redesigned to provide a 10+1+1 phase power supply design. Replacing the 8+6pin from the public version to the dual 8pin will inevitably provide more capital for overclockers and demonstrate the power of the 28nm process.
Specific specifications, ASUS Radeon HD 7970 DirectCu II graphics card default frequency of 1000/5600MHz (public version of 925/5500MHz), other specifications and the public version is exactly the same, with 2048 stream processors, with 3GB of GDDR5 memory, memory bandwidth 384bit . The output interface section provides two DVI interfaces and four Display Port interfaces.
The heat sink section is not much different from the previous DirectCu II GTX 580. It is also a 3-slot design with dual fans and six pure copper heat pipes. The difference is that Radeon HD 7970 DirectCu II provides a "VGA HotWire (Variable resistor through software, unique features of the player's country R4E, very easy to operate)" interface, can be with the player country Rampage IV Extreme motherboard "VGA HotWire "Use with features.
Powerbanks are popular for charging smartphones and mobile tablet devices. A powerbank is a portable device that can supply power from its built-in batteries through a USB port. They usually recharge with USB power supply. Technically, a powerbank consists of rechargeable Lithium-ion or Lithium-Polymer batteries installed in a protective casing, guided by a printed circuit board (PCB) which provides various protective and safety measures. Due to its general purpose, powerbanks are also gaining popularity as a branding and promotional tool. Different brands and promotional companies use it as a promotional tool and provide a customized product.
Many powerbanks use the common 18650 size lithium-ion battery which may or may not be user-replaceable.
Capacity in mAh: mAh stands for milli Ampere-hour and measures the amount of power flow that can be supplied by a certain powerbank at a specific voltage. Many manufacturers rate their products at 3.7 V, the voltage of cell(s) inside. Since USB outputs at 5 V, calculations at this voltage will yield a lower mAh number. For example, a battery pack advertised with a 3000 mAh capacity (at 3.7 V) will produce 2220 mAh at 5 V. Power losses due to efficiency of the charging circuitry also occur.
Simultaneous charging and discharging: need to specify if the powerbank can be used while it is charging.
Number of output USB ports: This specifies the number of devices that can be charged simultaneously.
Output current rating: This specifies the current rating that it can charge maximum. The higher the number, the better the powerbank. This can vary from output port to output port.
Input Current Rating: Input current rating is the amount of current the powerbank is able to draw at its maximum level while getting charged.
Safety Protections: Over Voltage Protection, Over Charge Protections, Over Current Protections, Over Heat Protections, Short-Circuit Protections and Over Discharge Protections are the common safety measures observed with standard powerbanks.
LED Indications: The Led glows as per indicating the amount of charging ability left with the powerbank.
