The RTX 5090 has a thermal design power (TDP) of 575 watts, a notable increase from the 450 watts of the RTX 4090. This higher power draw necessitates a robust power supply and effective case ventilation to manage the additional heat generated. Users should ensure their systems are equipped to handle this increased demand to maintain optimal performance and hardware longevity.
To address thermal concerns, the RTX 5090 features a new dual flow-through cooling design in its Founders Edition. This system utilizes two fans to push cooler air over the GPU's heatsink fins, enhancing heat dissipation. Despite the increased power consumption, this design helps maintain manageable temperatures during intensive workloads. Proper airflow within the PC case remains essential to complement the GPU's cooling solution and prevent thermal throttling.
The ASUS ROG Strix RTX 4090 employs ASUS's advanced cooling technology, which includes a triple-fan setup and a large heatsink to effectively manage heat. This design ensures that the GPU operates within safe temperature ranges, even under heavy loads. ASUS's cooling solution is known for its efficiency and quiet operation, contributing to a pleasant user experience. However, users should still ensure adequate case ventilation to support optimal thermal performance.
Both GPUs support NVIDIA's Deep Learning Super Sampling (DLSS) technology, which utilizes AI to enhance image quality and performance. The RTX 5090 introduces DLSS 4, offering significant improvements over the previous version. DLSS 4 employs advanced AI algorithms to generate higher-quality frames, resulting in up to an 8x performance boost compared to traditional rendering methods. This advancement is particularly beneficial in achieving high frame rates at 4K resolutions with ray tracing enabled.
The RTX 5090 also incorporates Neural Shaders and improved real-time rendering capabilities, further enhancing visual fidelity and performance. These features contribute to more realistic lighting, shadows, and reflections in supported games and applications. The integration of AI-driven technologies signifies a shift towards more intelligent and efficient graphics processing, setting a new standard for future GPU developments.
The ASUS ROG Strix RTX 4090 supports DLSS 3, which already provides substantial performance gains by generating additional frames using AI. While DLSS 3 enhances gaming experiences, DLSS 4 in the RTX 5090 offers further refinements and performance improvements.
