ASUS Adds ROG EAH4870 MATRIX and EAH4850 MATRIX to its Lineup Graphics Cards


Asus unveiled the ASUS Republi

These "intelligent" cards are equipped with ROG-exclusive technologies:

- Integrated hardware and software for total graphics card control
- Customizable functions that provide a new level of control to gamers
- Twin fan control application to separately adjust Hybrid Cooler+ fans (for EAH4870 MATRIX)
- Accurate adjustments of GPU and memory voltages
- Complete monitoring of GPU/memory/Power IC/ambient temperatures
- Complete monitoring of GPU/memory/board power consumption
- Automatic control of fan speeds according to the GPU loading detection
- Energy efficiency



The new cards boast a stylish design, a futuristic Hybrid Cooler and a black circuit board. Both cards are equipped with the ASUS Super Hybrid Engine, Hybrid Cooler technology and iTracker, enabling 15% and 17% performance boosts in 3D mode while guaranteeing 54% and 28% less power consumption and much quieter cooling in 2D mode? fulfilling the varied needs of gamers.

ASUS' exclusive Super Hybrid Engine (SHE) technology showcases its intelligence via a two-fold process. First gathering detailed information about the GPU loading and temperature, memory and power IC; SHE then calculates an optimized solution for the best performance. All of this happens in real time, without requiring any tinkering from users?making it easy to achieve multi-level GPU and memory voltage adjustments.

Hybrid Cooler draws its inspiration from Hybrid cars. By combining the fan and heatsink on one card in a revolutionary way, the Hybrid Cooler delivers its targeted level of performance in the most energy-efficient manner possible. When required, the fan and heatsink will work together for optimum cooling. Fan speeds are automatically determined via the advanced GPU loading detection, providing users with proactive cooling and greater energy efficiency in the event of lower graphics utilization?much like Hybrid cars. In addition, the ASUS ROG EAH4870 MATRIX comes with the dual-fansink Hybrid Cooler+. The dual fansinks take good care of not only the GPU but also the Power ICs and memory modules to prevent overheating. The speeds of both fans are also automatically adjusted to offer extreme cooling under 3D mode?lowering GPU and Power IC temperatures by a whopping 7°C and 12°C in comparison to reference design boards. On top of this cooling capacity, the noise level of Hybrid Cooler+ is only 36dB versus generic designed fansinks that produce 59.3dB.

The iTracker feature is a component of ASUS' exclusive SHE technology, and offers four default profiles for gamers who desire one-click control over their graphics card's performance: Optimized Mode, Gaming Mode, Power Saving Mode, and Default mode. This application is also able to display real-time graphics card information that includes the GPU/shader/memory clock, GPU/memory voltage, GPU loading, GPU/memory/power IC/ambient temperature, and fan speed. In addition, the fifth profile?User Defined Mode?enables real-time adjustments to the GPU/shader/memory clock, GPU/memory voltage, and fan speeds to suit different individual requirements.

GPU and memory voltages are boosted from 1.265V/1.5V to 1.423V/1.58V; and from 1.245V/1.979V to 1.303V/2.052V respectively when the ROG EAH4870 MATRIX and EAH4850 MATRIX are running in 3D mode. This allows the GPU and memory clock performance of the ROG EAH4870 MATRIX and EAH4850 MATRIX to be boosted from 750MHz/1800MHz to 855MHz/2014MHz; and from 625MHz/1986MHz to 752MHz/2057MHz respectively. According to Asus, such performance upgrades help raise the ROG EAH4870 MATRIX and EAH4850 MATRIX's 3DMark Vantage Extreme Mode score from 3655 to 4195 and from 2910 to 3395?an unbelievable 15% and 17% speed improvement when compared to any other reference designed board.

In 2D mode, when less power consumption is required, the ROG EAH4870 MATRIX and EAH4850 MATRIX are able to reduce GPU and memory voltages from 1.316V/1.52V down to 1.1V/1.353V; and from 1.245V/1.979V to 1.15V/1.9V respectively for great energy savings. Furthermore, Auto Phase Switch technology optimizes the power supplied by the power phase for maximum power efficiency. In combining the voltage reduction with Auto Phase Switch technology, the ROG EAH4870 MATRIX and EAH4850 MATRIX's power consumption are lowered from 72.02W to 33.53W and from 51.36V to 36.99V respectively?a 54% and 28% in power savings when compared to any other reference designed board. Additionally, both Hybrid Cooler+ and Hybrid Cooler will help reduce fan rotation speeds in 2D mode, allowing users to enjoy much quieter cooling for comfortable computing environments.
