NVIDIA GeForce GTX 770 2GB Review Feat. ASUS DirectCU II GTX 770

Updated: May 30, 2013

ASUS DirectCU II Specific Features

Features from different manufactures can make a significant difference in the overall experience of using the card and the additions of things like software as well as the cards ability to work with that software add an additional element to the end users total experience of their product. Using a Large high-density thermal heat sink offers extensive fins for improved heat dissipation that results in a greater than reference thermal performance. The DirectCU design features 5 dissipation points with 125% larger dissipation area and optimized pitch made from high conductivity aluminum offering 20% cooler than the reference design and near silent operation with a specially tuned fan curve.

To keep your card dust free and clean ASUS uses an exclusive double sealed internal fan hub assembly which limits dust, debris and dander from building up internally and affecting rotation and improving operating lifespan. To further insure the extended lifespan of their cards ASUS has implemented Super Alloy Power, which includes the use of super high-end Japanese components that make up the Choke, CAPs and MOS that when seen up close look very clean and modern. Having these components allows the card to have much better performance values and the super alloy design has been implemented in key components like chokes, capacitors and MOSFETs, enabling an overall increase in the performance of each component. This translates into a 2.5 times longer lifespan by way of their 5K capacitors, 30 quieter operation by eliminating electrical noise and run 20% cooler performance than the reference based GTX 770.

The cards features a 10-phase Super Alloy Power that translates into there being an 8-phase controller win a digital IC on the GPUs PWM and an addition 2-phase on the memory PWM. The ASUS design offers 15% better power efficiency by way of an advanced DIGI+VRM. Thos works as the DIGI+ VRM intelligently transfers current among phases and results in less power loss. The delicate power control design efficiently brings power consumption from original 34.4W down to 28.7W. This technology also translates into 50% less EMI as DIGI+ VRM dynamically adjusts frequencies, which results in EMI drop to 20dB from the original 40dB. For real-time graphics tweaking and tuning ASUS offers up their very own GPU Tweak that allows users to control the various aspects of the cards voltages, frequencies, fans and more. GPU Tweak offers Widget monitoring of your cards settings, keeps your drivers and card BIOS up to date and also comes embedded with the R.O.G version of GPU-Z to view your cards information. Overclocking is made much easier by way of this software application as it allows on the fly alterations of all aspects of your ASUS video card.
