The company illustrates advancements in performance, cooling and reliability
Asus has announced the availability of the new ROG Strix and TUF Gaming graphics cards with the Nvidia GeForce RTX 4000 series of GPUs, starting with the top models GeForce RTX 4090 24 GB, RTX 4080 16 GB and RTX 4080 12 GB. Based on the new Nvidia Ada Lovelace architecture, the third generation GeForce RTX 40 Series GPUs offer gamers and creators new features such as neural rendering and other advanced features of the new platform. The new ROG Strix GeForce RTX 4090 has a 3.5-slot design consisting of a die-cast metal frame, cover and backplate. The ultra-rigid construction uses extremely tight tolerance frames to prevent the PCB from flexing or warping, while ensuring optimal airflow through an enlarged air intake at the rear along the entire 357mm long board profile . The heat dissipation surface is 30 percent larger than the previous generation ROG Strix GeForce RTX 3090. Instead of resting on a flat surface, the cooling tubes sink into the vapor chamber, allowing the heat to be transferred more efficient to the heatpipes, four of 8 mm and three of 6 mm, and from here to reach the fins of the heatsink. When subjected to a thermal load of 500 watts, this coupling achieves 5 ° C lower temperatures than a conventional vapor chamber design.
Asus has updated Axial-tech fans, with a thicker design featuring seven blades and full barrier rings that provide 23.8% higher airflow and 19.3% higher pressure than previous fans generation used on the ROG Strix GeForce RTX 3090. From a power point of view, a 12 + 4 phase system has been included, consisting of 70 amp power stages, with two stages for each phase powering the GPU, with a total number of 24 + 4 power stages. The on-board digital controller offers greater accuracy in power detection, as well as improved power conversion and balance to reduce noise and signal interference.
The TUF Gaming GeForce RTX 4090 is instead designed to offer a more minimal design. The TUF proposal is slightly thicker than the ROG model, with a 3.65-slot design, but with a length of about 348mm, for greater compatibility with current cases, while maintaining high performance, cooling and power management. level, according to the company. The GeForce RTX 4090 Gaming TUF uses a die-cast unibody shell that mates with an aluminum backplate to strengthen the overall structure and protect the PCB from sagging, while offering abundant airflow. The new 3D acrylic TUF logo runs along the cover and offers Aura Sync compatible ARGB lighting, while a detachable velcro loop offers practical cable management options. A large air intake on the edge of the backplate allows even more airflow through the larger Axial-tech fan fins, ensuring 20% more airflow than last generation GeForce RTX 3090 Ti TUF Gaming .
As in the ROG Strix variant, Asus has also re-engineered the cooling of the TUF Gaming card by developing a new vapor chamber to greatly improve heat transfer. The eight heatpipes, five 8mm and three 6mm, offer an increase in cooling potential, with a 35% larger contact area than the GeForce RTX 3090 TUF Gaming. As with the ROG Strix models, you can choose between performance and silent modes with the integrated Dual BIOS switch or adjust the card’s performance via the new GPU Tweak III software. To provide the necessary power, TUF Gaming’s GeForce RTX 4090 uses the new PCIe 5.0 standard 16-pin power connector, which provides a power delivery system with 20K capacitors and a series of high-performance power stages. power arranged in 10 + 4 configuration. ROG Strix GeForce RTX 4090 and TUF Gaming GeForce RTX 4090 are already available at a recommended retail price starting from 2,399 euros for the TUF Gaming GeForce RTX 4090 24GB GDDR6X model.
