GALAXY's Brazilian overclocking team overclocked a GALAXY RTX 4090 SG graphics card to 3.45GHz under liquid nitrogen cooling, breaking 5 world records. The RTX 4090 has a very good overclocking performance, and it can easily achieve a frequency of 3075MHz under air cooling.
In order to achieve higher frequencies, the overclocking team removed the graphics card's power-limiting controller, eventually achieving a frequency of 3.45GHz. But for stability, the team managed to break world records in five benchmarks using GPU speeds of 3270-3375 MHz, including 3DMark Ultra 28 553 points, 3DMark Port Royal 29 304 points, 3DMark Time Spy Extreme 21949 points, and more.
The NVIDIA RTX 40 GPU uses a 5nm-based TSMC 4N process with 76 billion transistors, 16,384 CUDA cores, and 24 GB of high-speed Micron GDDR6X video memory, which continues to run at more than 100 FPS in 4K resolution games.
By default, the RTX 4090 is 450W TDP, and the power consumption can reach 496W to 667W when using overclocking software. Additionally, limiting the power consumption of the RTX 4090 to 300W results in a 9% performance penalty and only 6% at 350W.
