ASUS has released its top of the line GeForce GTX 780 graphics card in its GeForce GTX 780 DirectCU II OC. This card features NVIDIA’s GK110-300 core, has 2304 CUDA cores, 3 GB of GDDR5 memory and has a engine clock of 941 MHz. The card features an ASUS designed PCB and an all new DirectCU II cooling system.
ASUS engineers developed a new thermal design that revolves around a direct-GPU contact 10mm copper heatpipe, compared to traditional 8mm heatpipes. This new design contributes up to a 40% improvement in heat transfer efficiency. The cooler also utilizes a custom designed heatsink, which ensures a significantly larger heat dissipation surface area. Extensive testing guarantees the redesigned ASUS DirectCU II cooler features up to 30% lower temperatures and up to three times quieter performance under heavy loads compared to a reference GTX 780.
The proprietary CoolTech fan used on GeForce GTX 780 DirectCU II cards enables 360-degree airflow that is much more effective than traditional fans at the same RPM. It consists of a hybrid blade and bearing design, with an inner radial blower and outer flower-type blades. Combined, they provide multi-directional airflow to accelerate heat removal and enable consistently cool and quiet graphics card performance.
ASUS includes exclusive DIGI+ VRM digital voltage regulation on the GeForce GTX 780 DirectCU II OC card. Precise power delivery means up to 30% lower power noise than reference designs along with improved stability and overclocking margins.
Super Alloy Power solid state capacitors, chokes, and MOSFETs use custom alloy formulations to ensure improved efficiency, superior stability, reduced operating temperatures and increased voltage thresholds during intense gaming and overclocking sessions. Compared to reference designs, the GeForce GTX 780 DirectCU II OC features components with up to 2.5 times longer lifespans for increased reliability.
The card will begin shipping in about a week.
