Verdict

The ASUS ROG Strix GeForce RTX 4090 is a flagship graphics card featuring the NVIDIA Ada Lovelace architecture with 16,384 CUDA cores and 24GB of GDDR6X VRAM on a 384-bit interface. It offers a massive 3.5-slot cooling design with a patented vapor chamber and Axial-tech fans that provide 23% more airflow for chart-topping thermal performance. Key pros include exceptional 4K and 8K gaming performance, advanced DLSS 3 support, and dual BIOS for quiet or performance modes. Main cons are its extremely high price, massive physical size requiring a large case, and high power consumption that recommends at least a 1000W power supply.
